Glossary of active ingredients

Acetyl Hexapeptide-8

Acetyl Hexapeptide-8 (Argireline)

Acetyl Hexapeptide-8 (known as Argireline) is a synthetic hexapeptide designed as a biotechnological alternative to botulinum toxin — without medical intervention. It works by inhibiting the release of neurotransmitters responsible for the contraction of expression muscles, thereby reducing dynamic wrinkles (crow's feet, frown lines, forehead lines). Unlike Botox, it does not paralyse the muscles but subtly limits their reactivity, which makes the effect natural and free of the risk of a frozen "mask". Clinical studies have proven a reduction in wrinkle depth of up to 30% after 30 days of regular use. Recommended in anti-wrinkle products for mature skin with visible expression lines, particularly around the eyes and forehead.

A biomimetic peptide that builds the dermal matrix. It protects the skin's structure and slows the aging process. Found in key Forever Young products and eye-area products.

AHA Acids (Alpha Hydroxy Acids)

Alpha Hydroxy Acids (AHA)

AHA acids (alpha hydroxy acids) are a group of natural fruit-derived acids — glycolic, lactic, malic, citric and mandelic — found in sugar cane, milk, apples, citrus fruits and bitter almonds. Because they are water-soluble, they act on the surface of the epidermis, where they loosen the bonds between dead corneocytes and initiate the process of chemical exfoliation. They stimulate collagen synthesis, accelerate cell renewal and improve the penetration of other active ingredients. They effectively smooth wrinkles, reduce discolouration, even out skin tone and give the skin a fresh, youthful look. Ideal for caring for dull, mature and photoaged skin — they absolutely require an SPF cream in the morning.

Allantoin

Allantoin

Allantoin is one of the most versatile cosmetic ingredients, occurring naturally in plants (e.g. comfrey) and animals. In cosmetics it works on several fronts — it soothes irritation, calms redness and accelerates the skin's natural regeneration. It has keratolytic properties (gently exfoliating) as well as keratoplastic ones (promoting epidermal rebuilding), which smooths the skin's texture. It also acts as an emollient, softening the skin and improving its elasticity, and as a humectant that retains moisture. Ideal for all skin types, especially sensitive, damaged skin, skin after dermatological treatments or after excessive sun exposure.

Alpha-Lipoic Acid

Alpha-Lipoic Acid

Alpha-lipoic acid (ALA) is a unique universal antioxidant — one of the few active ingredients soluble in both water and fats, which is why it protects skin cells both inside and on their membranes. It has the ability to regenerate other antioxidants (vitamins C and E, glutathione and coenzyme Q10), thereby strengthening the skin's entire defence system against free radicals. It effectively reduces wrinkles, improves skin texture, evens out skin tone and supports microcirculation. It also has a gentle exfoliating and anti-inflammatory action — recommended for skin with photoaging, hyperpigmentation and signs of fatigue. An ideal ingredient in advanced anti-age products for mature, dull skin exposed to pollution and oxidative stress.

Alpine Rose Stem Cells

Alpine Rose Stem Cells

Alpine Rose stem cells are an innovative biotechnological ingredient derived from a plant that grows in the extreme conditions of the Alps — severe frost, intense UV radiation, and drought. They activate the skin's defense mechanisms, strengthen its natural resistance to environmental stress, and support the resilience of the epidermis's own stem cells. Thanks to the presence of flavonoids and gallic acid, they have antioxidant and anti-inflammatory action, protecting the skin from the effects of air pollution, blue light (HEV), and UV exposure. Ideal for skin exposed to urban conditions and photodamage, they support regeneration and delay aging processes. This is a key ingredient in the Christina Muse line, designed for people 25+ seeking early-stage aging prevention.

A marine polysaccharide that stimulates the skin's endogenous production of hyaluronic acid. Soothes and supports regenerative processes. An ingredient of Moisture Fusion.

Anti-Aging Peptides

Anti-Aging Peptides

Anti-aging peptides are short chains of amino acids that act in cosmetics as signals to skin cells, instructing them to carry out specific actions — most often the production of collagen, elastin and hyaluronic acid. There are three main groups of peptides: signal peptides (e.g. matrixyl), carrier peptides (e.g. copper peptides) and neurotransmission-inhibiting peptides (e.g. argireline). They stimulate fibroblasts to regenerate the intercellular matrix, resulting in reduced wrinkles, improved firmness and a better facial contour. They are gentle and non-irritating, so they can be used by every skin type, including sensitive and reactive skin. This is the gold standard of modern, science-based anti-age skincare.

Antiglycation Complex

Antiglycation Complex

The antiglycation complex is an advanced active ingredient that protects the skin's structural proteins — collagen and elastin — against glycation, the uncontrolled binding of sugars to proteins. Glycation leads to the formation of AGEs (advanced glycation end-products), which stiffen collagen fibers, destroy elastin, and cause loss of skin firmness. Thanks to the presence of carnosine, black tea extract, and alpha-lipoic acid, the complex neutralizes free radicals and inhibits the glycation process at its source. Regular use noticeably improves skin tone, reduces wrinkles, and restores a youthful, supple appearance to the complexion. The ingredient is especially recommended in anti-age care for people over 35 and for mature skin showing signs of photoaging.

The classic "natural Botox" peptide, in use since 2003. It blocks neuromuscular transmission (acetylcholine) — the muscle does not receive the signal to contract, and expression wrinkles are reduced.

Arnica

Arnica Montana Extract

Mountain arnica (Arnica Montana) is a medicinal plant growing in the mountains of Europe and North America, known in phytotherapy for centuries. Rich in active compounds: sesquiterpene lactones (helenalin), flavonoids and triterpenes, which have strong anti-inflammatory, soothing and anti-edema action. In cosmetics it is used mainly in preparations for vascular and couperose skin — it strengthens the walls of blood vessels, reduces redness and broken capillaries. It effectively speeds up the absorption of hematomas and bruises, which is why it is often recommended in products after invasive treatments (mesotherapy, fillers). It also works well in the care of tired, swollen legs with circulatory problems. Ideal for sensitive, vascular and reactive skin.

A complex of French and Sicilian rose for the eye area. Increases elastin and collagen synthesis, reduces eyelid drooping and smooths crow's feet.

Caffeine

Caffeine

Caffeine in cosmetics is a highly active ingredient with a broad spectrum of action — mainly stimulating microcirculation and providing a draining effect. Thanks to its lipolytic and vasoconstrictive properties, it reduces puffiness and dark circles under the eyes and helps combat cellulite and excess fatty tissue. It contains strong antioxidants that neutralise free radicals and protect the skin against photoageing and UV-induced DNA damage. It effectively stimulates fibroblasts to produce collagen, thereby improving skin firmness and tone. Ideal in eye products, anti-cellulite formulas and firming preparations for the body and face.

Carnosine

Carnosine

Carnosine is a natural dipeptide composed of two amino acids — β-alanine and histidine — found in human muscle and nerve tissue. In cosmetology it serves as a powerful antioxidant and antiglycation agent, protecting the skin against two key mechanisms of aging: oxidative stress and the glycation of structural proteins. It neutralizes free radicals, protects cellular mitochondria from damage, and supports the skin's native DNA repair processes. After regular use, the skin becomes visibly firmer, smoother, with less visible wrinkles and improved tone. The ingredient is especially recommended in premium skincare for mature, dull skin and skin with signs of photoaging.

Centella Asiatica

Centella Asiatica Extract

Centella asiatica, also known as "tiger herb" or "gotu kola", is a plant used for thousands of years in Ayurvedic and traditional Asian medicine to heal wounds. It contains unique triterpenes — asiaticoside, madecassoside and asiatic acid — which stimulate collagen synthesis and strengthen microcirculation and blood vessel walls. It has a strong anti-inflammatory and soothing action, effectively reducing redness, supporting the regeneration of damaged skin and alleviating the symptoms of rosacea. It strengthens the protective barrier and counters the effects of stress on the skin, which is why it is a key ingredient in the care of sensitive, vascular skin and skin with couperose. Ideal for those with reactive skin seeking a natural yet effective solution.

Ceramides

Ceramides

Ceramides are a complex of lipids that occur naturally in the stratum corneum of the epidermis, where together with cholesterol and fatty acids they form the intercellular cement — the fundamental structure of the skin's protective barrier. They make up about 50% of epidermal lipids, and their level drops drastically with age (by 30% after the age of 30) and under the influence of environmental factors, leading to a weakened barrier and dry, sensitive skin. Ceramide supplementation in cosmetics replenishes deficiencies, rebuilds the intercellular cement, prevents transepidermal water loss (TEWL) and soothes reactivity. It effectively strengthens atopic, allergic and sensitive skin, as well as skin suffering from barrier disorders (e.g. after retinoids, acids or treatments). It is one of the most fundamental ingredients in modern cosmetology — an essential element of every good skincare routine.

Coral Powder

Coral Powder

Coral powder is a unique, 100% natural exfoliant obtained from the calcareous skeletons of Mediterranean corals. It is the key ingredient of Christina's iconic Rose de Mer line — one of the most recognizable peeling protocols in the world. The coral particles have a unique structure — sharp-edged grains that, combined with natural essential oils (cinnamon, clove), create micro-injuries that activate the skin's natural regenerative response. It stimulates the production of new collagen fibers, reduces post-acne scars, evens out skin tone and restores radiance. Recommended in professional in-clinic treatments for mature skin, photoaging, scars and uneven texture — with results comparable to microdermabrasion and chemical peels.

Cotton Flower Extract

Gossypium Herbaceum Extract

Cotton flower extract (Gossypium Herbaceum) is a gentle, versatile ingredient with softening and moisturizing properties. It forms an invisible protective film on the skin's surface that guards against transepidermal water loss (TEWL) and environmental factors. Rich in bio-flavonoids and tocopherols, it provides antioxidant and anti-inflammatory action, counteracting the effects of oxidative stress. It is ideal for the care of dehydrated, irritation-prone skin and for use after procedures such as peeling or microdermabrasion. Regular use smooths texture, restores softness, and gives the skin a healthy, natural appearance.

Cupuaçu Butter

Theobroma Grandiflorum Seed Butter

Cupuaçu butter is a luxurious ingredient obtained from the seeds of a tree native to the Amazon rainforest, often called a "natural alternative to lanolin." It is characterized by an exceptional water-absorption capacity — retaining up to 240% of its own weight, which makes it a powerful humectant and emollient. Rich in omega-9 fatty acids and phytosterols, it deeply nourishes, regenerates the lipid barrier and improves skin elasticity. It works perfectly in the care of dry, dehydrated and mature skin, as well as after exfoliating treatments. Used regularly, it gives the skin softness, silky smoothness and a natural glow.

A peptide that inhibits melanogenesis by blocking tyrosinase. It evens out skin tone and reduces discolouration without the risk of lightening the entire complexion.

Diacetyl Boldine

Diacetyl Boldine

Diacetyl Boldine is a synthetic active ingredient derived from boldo tree (Peumus boldus) extracts, with strong brightening and antioxidant action. It works by selectively inhibiting tyrosinase — the enzyme responsible for melanin synthesis in melanocytes — without the cytotoxic effect seen with hydroquinone. It effectively reduces sun spots, melasma, age spots and post-inflammatory hyperpigmentation (PIH). It also acts as an antioxidant, protecting the skin from free radicals and preventing the formation of new discolouration. An ideal ingredient for skin with hyperpigmentation and photoaging, and for those seeking a safe alternative to aggressive brightening methods — used, among others, in Christina's Illustrious line.

Elasticity Enhancer

Elasticity Enhancer Complex

Elasticity Enhancer is an advanced active complex designed specifically to strengthen the skin's fitness fibres — elastin and collagen. It consists of synergistic biopeptides that stimulate elastin synthesis in fibroblasts and inhibit elastase enzymes, which are responsible for breaking down existing fitness fibres. It works in multiple directions — not only stimulating the production of new elastin, but also preserving the skin's existing structural network. After regular use, a clear improvement in skin tension, tone and resistance to gravity is observed, and wrinkles become less visible. An ideal ingredient in intensive anti-ageing care for mature skin with sagging tissues and lax skin.

A biomimetic peptide that mimics the epidermal thymic factor. It compensates for the natural decline in thymus activity with age. It strengthens the skin's defence mechanisms and activates the synthesis of collagen and fibronectin — the foundation of the Forever Young line since 2003.

Ferulic Acid

Ferulic Acid

Ferulic acid is an organic phenolic acid that occurs naturally in plant cell walls (mainly in grains, rice, oats and apples), where it serves as their natural shield against UV radiation. In cosmetics it is used primarily as a powerful next-generation antioxidant — significantly more effective than vitamin C or E alone. It shows an exceptional synergistic effect: combining ferulic acid with vitamins C and E strengthens their photo-protection up to 8-fold, which is why it is an indispensable ingredient in antioxidant daytime formulas. It effectively protects against photoaging, reduces hyperpigmentation, counteracts oxidative stress and prevents the formation of wrinkles. Ideal in SPF products, antioxidant daytime serums and for skin exposed to UV radiation and urban pollution.

Firming Peptide

Firming Peptide

Firming Peptide is an advanced cosmetic signal peptide that stimulates skin fibroblasts to produce type I and III collagen fibres and elastin. It works by activating the cell receptors responsible for synthesising the extracellular matrix — the scaffolding that keeps skin firm and taut. After 4-6 weeks of regular use it visibly improves facial contour, lifts the cheeks and redefines the jawline, reducing tissue sagging. The skin gains greater density, elasticity and resistance to gravity, while fine lines are smoothed from within. An ideal ingredient in anti-ageing care for mature skin showing signs of lost firmness, particularly after the age of 40.

Flax Extract

Linum Usitatissimum (Flax) Extract

Flax extract (Linum Usitatissimum) is a rich source of unsaturated omega-3 fatty acids (alpha-linolenic acid, ALA), lignans and phytosterols with a strong smoothing and regenerating effect. Lignans act as phytoestrogens that support the firmness and hydration of mature skin, particularly in peri- and postmenopausal women. Omega-3 fatty acids strengthen the hydrolipidic barrier, reduce transepidermal water loss and counter inflammation. The ingredient also acts as an antioxidant, protecting the skin against free radicals and photoageing. Ideal in the care of mature, dry skin and skin showing signs of expression lines and fine furrows.

A peptide that stimulates skin renewal and bio-mechanical activity. It supports the synthesis of collagen, elastin and laminin. The skin becomes more elastic and firmer.

Glycolic Acid

Glycolic Acid (AHA)

Glycolic acid is the smallest and most active of the AHA (alpha-hydroxy acids) group — thanks to its low molecular weight, it penetrates deep into the layers of the epidermis. Derived from sugar cane, it works by loosening the bonds between dead corneocytes, initiating the process of chemical exfoliation. It stimulates the synthesis of new collagen and accelerates cell renewal, thereby smoothing wrinkles, reducing hyperpigmentation, and improving skin texture. It effectively unclogs pores, reducing imperfections and blackheads, which is why it works well in the care of oily, problematic skin and skin with signs of photoaging. It requires the use of an SPF cream — it increases the skin's sensitivity to UV radiation.

Goji Berry Exosomes

Goji Stem Cell Exosomes

Goji berry stem cell exosomes are a breakthrough technology in anti-aging cosmetology — microscopic vesicles that transport regenerative signals between skin cells. They activate the skin's native DNA repair mechanisms and stimulate the production of type I and III collagen at the cellular level. Thanks to the presence of carotenoids, polysaccharides, and micro-RNA, they protect telomeres from shortening, genuinely slowing the aging process. After treatment, the skin becomes visibly firmer, smoother, with improved tone and reduced fine wrinkles. An ideal ingredient in advanced anti-age care for mature skin and in premium-line products.

Gotu Kola

Centella Asiatica (Gotu Kola)

Centella Asiatica, also known as Gotu Kola, is a plant with over 2,000 years of history in Ayurvedic and traditional Chinese medicine, where it is called the "herb of longevity." It contains unique triterpenes: asiaticoside, madecassoside, asiatic acid and madecassic acid, which stimulate the synthesis of type I and III collagen and activate fibroblasts to regenerate the extracellular matrix. It has been clinically proven to accelerate wound healing, reduce post-acne scars and strengthen blood vessels. It has strong anti-inflammatory and antioxidant action, soothing redness and easing the symptoms of rosacea. An ideal ingredient in the care of sensitive skin, skin regenerating after treatments, and in firming products — reliable in the care of reactive and couperose skin.

A next-generation encapsulated retinoid — stable under light and oxygen. Delivers retinol-like results without the irritation typical of classic retinol.

Next-Generation Retinol

Hydroxypinacolone Retinoate (HPR)

Hydroxypinacolone Retinoate (HPR) is a latest-generation retinoid — an ester derivative of retinoic acid that acts directly on the skin's retinoid receptors without the need for metabolic conversion. Unlike classic retinol, which must be converted into retinoic acid (a multi-step process that is taxing for the skin), HPR works immediately, so it does not cause flaking, irritation or sun sensitivity. It stimulates collagen production, accelerates cell renewal, and reduces wrinkles, discolouration and signs of photoaging. It achieves efficacy comparable to retinol with far better tolerance — making it ideal for sensitive, dry skin and for those just starting out with retinoids. It is a breakthrough ingredient in modern anti-age skincare — the effects of younger-looking skin without the cost of "retinisation".

Hyaluronic Acid

Sodium Hyaluronate

Hyaluronic acid is a natural polysaccharide found in the skin's extracellular matrix, in hair, and in the synovial fluid of joints — one of the most important ingredients for maintaining a youthful appearance. A single molecule can bind up to 1000 times more water than its own weight, making it the strongest known humectant. It fills wrinkles from within, restores volume and firmness to the skin, and at the same time strengthens its protective barrier. After the age of 30, the body's natural production of hyaluronic acid drops by 50%, which is why cosmetic supplementation in the form of serums and creams is especially important. It is ideal for all skin types, particularly for dehydrated, mature, and wrinkle-prone skin.

Hydrolyzed Rice Protein

Hydrolyzed Rice Protein

Hydrolyzed rice protein is a natural ingredient obtained from rice grains through controlled enzymatic hydrolysis, which breaks proteins down into small, low-molecular-weight peptides. It is rich in essential amino acids (lysine, leucine, arginine), the building blocks of keratin and collagen — the main structural proteins of the epidermis. It penetrates deep into the skin, where it rebuilds the hydrolipid barrier, strengthens the structure and increases resistance to damage. It also acts as a natural moisturising factor (NMF), retaining moisture in the intermediate layers of the epidermis. Ideal for mature, dry skin with wrinkles and loss of elasticity — especially recommended in firming and strengthening products.

Hydrolyzed Silk

Hydrolyzed Silk

Hydrolyzed silk is a luxurious cosmetic ingredient obtained from natural silk fibres, broken down into low-molecular-weight peptides known as fibroin. Thanks to its small molecular size, it penetrates deep into the skin, where it forms a microscopic film with silky comfort and an invisible lifting effect. Rich in natural amino acids (serine, alanine, glycine), which are building blocks of keratin and other epidermal proteins and support its structure. It effectively hydrates, smooths the texture and gives the skin an incredibly soft, silky appearance. It is a key ingredient of Christina's Silk line — dedicated to reducing wrinkles and giving skin a silky smoothness.

Jania Rubens Red Algae

Jania Rubens Extract

Jania Rubens red algae are mineral-rich marine plants from the Mediterranean coast that provide deep remineralizing action in cosmetology. They contain high concentrations of calcium, magnesium, silicon, and fluorochrome, which strengthen the skin, improve its firmness, and even out tone. They have an anti-wrinkle effect, activate microcirculation, and support collagen synthesis, giving the skin optimal density and tone. They are ideal for the care of tired, mature skin and for reaffirming and lifting products. Regular use restores radiance and energy to the complexion and visibly improves the facial contour.

Jojoba Oil

Simmondsia Chinensis (Jojoba) Seed Oil

Jojoba oil (Simmondsia Chinensis) is a liquid wax ester extracted from the seeds of the jojoba shrub native to North American deserts — structurally the closest match to the skin's own natural sebum. Thanks to this compatibility it is perfectly recognised by the skin, penetrates quickly and acts as an "impostor": it signals the sebaceous glands that there is enough sebum, thereby regulating its overproduction. Rich in vitamins A, E and F as well as phytosterols, it delivers antioxidant, regenerating and anti-inflammatory benefits. It does not clog pores (comedogenicity rating 0–2), which is why it paradoxically works just as well for oily and acne-prone skin as for dry and mature skin. An ideal ingredient for the daily care of all skin types — in cleansing oils, massage oils, serums and balancing creams.

Kojic Acid

Kojic Acid

Kojic acid is a natural active ingredient obtained from Aspergillus oryzae fungi — originally discovered in the Japanese fermentation of sake rice. It works by inhibiting tyrosinase — the key enzyme in melanin synthesis in melanocytes — thereby effectively brightening existing hyperpigmentation and preventing the formation of new spots. It has strong antioxidant action, neutralizing free radicals responsible for photoaging and the fixation of hyperpigmentation. It effectively reduces sun spots, melasma, hormonal and post-inflammatory hyperpigmentation (PIH). Recommended for skin with hyperpigmentation, photoaging and after dermatological treatments — an alternative to aggressive hydroquinone with a better safety profile, a key ingredient of Christina's Illustrious line.

Low Molecular Weight Hyaluronic Acid

Low Molecular Weight HA

Low molecular weight hyaluronic acid (LMW HA) is a special form of hyaluronic acid with a molecular weight below 50 kDa, which thanks to its small molecule size effectively crosses the stratum corneum barrier. While classic high molecular weight hyaluronic acid works mainly on the surface, the low molecular weight form penetrates deep into the skin — all the way to the layers of the dermis. There it binds water, fills wrinkles from within, stimulates fibroblasts to produce native HA and collagen, and delivers anti-aging benefits at a structural level. It has been clinically proven that regular use increases skin hydration, reduces fine lines and improves skin density. Ideal in intensive anti-wrinkle products for mature, dehydrated skin and skin with structural wrinkles.

Magnolia Extract

Magnolia Extract

Magnolia extract is obtained from the bark of the magnolia tree (Magnolia officinalis) — a plant used in traditional Chinese medicine for over 2,000 years. It contains unique lignans: magnolol and honokiol, which have strong anti-inflammatory, antibacterial and antioxidant action. They inhibit the activity of key inflammatory mediators (NF-kB, COX-2), thereby effectively reducing redness, itching and symptoms of skin hypersensitivity. It has been clinically proven that the use of magnolia extract eases the symptoms of rosacea, atopic dermatitis and allergic reactions. An ingredient particularly recommended in soothing preparations for sensitive, reactive skin and in care after dermatological treatments.

A matrikine peptide that signals to fibroblasts that the matrix is being destroyed and "forces" them to synthesise new molecules of collagen, fibronectin and HA.

Melatonin

Melatonin

Melatonin is a hormone naturally produced in the human body by the pineal gland, responsible for regulating the circadian rhythm and the process of falling asleep. In cosmetics, its strong antioxidant action is harnessed — it is one of the most powerful free-radical scavengers, working in both aqueous and lipid environments. It supports the skin's nighttime regeneration, when cell renewal processes are most intense, and synchronises the fibroblasts' work cycle with the natural circadian rhythm. It has been clinically proven that its use increases skin hydration, reduces wrinkles and improves skin density. An ideal ingredient for night creams for mature, tired skin exposed to environmental stress and photoaging.

Niacinamide

Niacinamide (Vitamin B3)

Niacinamide (vitamin B3) is a versatile active ingredient, one of the best-studied in dermatology — with documented efficacy across many categories of skin concerns. It works in multiple directions: it strengthens the hydrolipid barrier by stimulating ceramide production, inhibits the transfer of melanin to keratinocytes (brightens hyperpigmentation), regulates sebum secretion, and reduces the appearance of pores. It has strong anti-inflammatory action, reducing redness, soothing rosacea, and calming skin reactivity. It suits all skin types and combines well with all other active ingredients (including AHA/BHA acids and retinol). The best results are observed at concentrations of 4-10% and with regular use for at least 8 weeks.

A complex of pomegranate, yeast and ribonucleotides. Energizes the skin — adding vitality to tired, dull complexions.

Niosomal delivery technology carrying hydrolyzed hyaluronic acid (50 kDa) and kaempferol deep into the epidermis — an alternative to injectable fillers.

Peptide Q10

Peptide + Coenzyme Q10

Peptide Q10 is an advanced combination of a synthetic signal peptide with coenzyme Q10 (ubiquinone), which occurs naturally in the mitochondria of cells. Q10 is essential for producing ATP — the molecule of cellular energy — and its levels drop dramatically after the age of 40, leading to a loss of skin vitality. Combining it with a peptide increases bioavailability and allows deep penetration, so the ingredient works at the cellular level. It energises fibroblasts, stimulates collagen synthesis, reduces wrinkles and improves microcirculation, helping the skin regain its radiance and even tone. Recommended in anti-ageing care for tired, sallow skin with signs of photoageing.

A plant-derived ingredient that strengthens the skin barrier and cell adhesion. It stimulates the production of desmosomes — providing long-lasting hydration and resistance to external factors.

An intelligent silicone film that fills in wrinkles and reflects light rays. It delivers an instant smoothing effect on the skin's surface — a key ingredient in Total Renewal Serum.

Probiotics

Probiotics (Lactobacillus)

Probiotics in cosmetics are live or freeze-dried probiotic bacteria (mainly Lactobacillus and Bifidobacterium strains) and their metabolites (postbiotics) that support the skin microbiome. The microbiome — the unique ecosystem of microorganisms living on the skin's surface — plays a key role in maintaining skin health and immunity. Probiotics restore the balance of the microbiome disrupted by stress, harsh cosmetics and pollution, with the resulting benefits being a stronger protective barrier and better resilience. They effectively reduce inflammation, redness and irritation, and ease the symptoms of acne, atopic dermatitis and rosacea. This is one of the most modern trends in cosmetics — an ideal ingredient for reactive, sensitive skin and skin with a disrupted hydrolipid barrier.

Regu-age

Regu-age (Soy + Rice peptides)

Regu-age is a clinically tested complex of soy and rice peptides designed specifically for the delicate eye area — one of the most challenging areas to care for. It consists of hydrolysates of soy, rice, and yeast proteins containing active biopeptides with antioxidant and draining action. Its mechanism of action is based on strengthening microcirculation, reducing excessive vascular permeability, and inhibiting glycation — the three main causes of dark circles and puffiness under the eyes. Clinical studies have shown a reduction in bags and dark circles of up to 60% after 8 weeks of consistent use. The ingredient is especially recommended in eye products for people who are tired, stressed, and showing the first signs of aging.

A polyphenol from red grapes — a powerful antioxidant. Activates sirtuins (the "longevity genes"), protecting against oxidative stress and photoaging.

Retinol

Retinol (Vitamin A)

Retinol is the pure form of vitamin A, one of the best-studied and most effective anti-age ingredients in dermatology — the gold standard of modern cosmetology. In the skin it converts to retinoic acid, which binds to nuclear receptors (RAR/RXR), activating genes responsible for the synthesis of collagen and elastin and for accelerating cell turnover. It effectively reduces wrinkles, evens out skin tone, inhibits melanin production in hyperpigmentation and regulates sebaceous gland function in acne-prone skin. First effects are visible after 4 weeks, full effects after 12 weeks of regular use. It requires careful introduction (start with low concentrations, 2-3x per week) and absolutely an SPF cream in the morning — retinol makes the skin more sensitive to UV radiation. Best results in mature skin with wrinkles, photoaging and hyperpigmentation.

Rose Extract

Rosa Gallica Flower Extract

Gallic rose extract (Rosa Gallica) is one of the oldest ingredients in Mediterranean cosmetology, valued for its soothing and regenerating action. Rich in polyphenols, flavonoids and natural essential oils that effectively reduce inflammation, redness and irritation. It strengthens blood vessels, which is why it works excellently in the care of vascular skin, couperose and sensitive complexions prone to reactivity. It additionally hydrates, restores comfort and gives the complexion a fresh, healthy appearance. Ideal for everyday care of sensitive, redness-prone skin.

Salicylic Acid

Salicylic Acid (BHA)

Salicylic acid is an organic BHA (beta-hydroxy acid) derived from white willow bark, one of the best-studied ingredients in anti-acne dermatology. Unlike AHA acids, it is oil-soluble, so it penetrates oily pores and clears them from within, dissolving sebum, blackheads and excess dead skin cells. It also acts keratolytically, anti-inflammatorily and antibacterially, inhibiting the growth of Cutibacterium acnes bacteria responsible for acne lesions. It effectively reduces breakouts, papules, open and closed comedones, evens out skin tone and minimises the appearance of pores. It is the gold standard in skincare for oily, problematic and acne-prone teenage skin — featured in Christina's signature Comodex line.

Sericin

Sericin (Silk Protein)

Sericin is a natural silk protein that surrounds fibroin fibres, obtained during the processing of mulberry silkworm cocoons. In cosmetics it acts as a natural film-forming ingredient that creates an invisible structure on the skin's surface, with an immediate tightening and smoothing effect. Rich in 18 amino acids (including serine, threonine, glycine), it penetrates the epidermis and strengthens the natural protective barrier while increasing hydration levels. It has antioxidant and anti-inflammatory properties, protecting the skin against oxidative stress and photoageing. Ideal in products with an immediate lifting effect — it gives the skin an almost silky smoothness and radiance, which is why it is the signature of Christina's luxurious Silk line.

Shea Butter

Butyrospermum Parkii (Shea Butter)

Shea butter (Butyrospermum Parkii) is a natural fat obtained from the nuts of the karité tree (Vitellaria paradoxa), which grows in the savannahs of West Africa. Exceptionally rich in active cosmetic ingredients: vitamins A, E and F, fatty acids (oleic, stearic), phytosterols and triterpenes with strong regenerative action. It forms a protective film on the skin that prevents water loss and shields against environmental factors. It is anti-inflammatory, regenerating and smoothing — ideal for the care of dry, crack-prone, atopic and irritated skin. It also stimulates collagen synthesis and has anti-age properties, making it well suited to products for mature skin.

Broad-Spectrum SPF 30 Protection

Broad-spectrum UVA/UVB filters

Broad-spectrum SPF 30 protection is a combination of next-generation UV filters — both chemical (organic) and mineral — providing effective defense against UVA and UVB radiation. UVB filters protect against sunburn and erythema, while UVA penetrates deeper and is responsible for photoaging, hyperpigmentation, and loss of firmness. An SPF 30 factor blocks about 97% of UVB radiation and is recommended for daily care in urban conditions. Using SPF products is the foundation of preventing premature skin aging, melanoma, and pigmentation changes. It is an absolute must-have in the skincare routine for every skin type, regardless of the season.

Squalane

Squalane

Squalane is a saturated hydrocarbon obtained through the hydrogenation of squalene (a component naturally present in skin sebum) — its stable, non-oxidising form. Structurally identical to epidermal lipids, it is therefore exceptionally well accepted by the skin, absorbs quickly and leaves no greasy film. It effectively rebuilds the hydrolipid barrier, prevents water loss (TEWL), smooths the skin and gives it a silky softness. It has antioxidant action, protecting against free radicals and photoaging, and shows anti-inflammatory properties. Ideal for all skin types, including acne-prone, dry, mature and sensitive skin — non-comedogenic and hypoallergenic.

An advanced amino acid complex (alanine + proline + serine). Repairs skin damage within 24 h, reduces TEWL (transepidermal water loss) and strengthens the protective barrier.

Sweet Almond Oil

Sweet Almond Oil

Sweet almond oil is a natural oil pressed from the seeds of the almond tree (Prunus Amygdalus Dulcis) — one of the oldest and most versatile cosmetic ingredients. Rich in monounsaturated and polyunsaturated fatty acids (oleic, linoleic), vitamins A, E and B, and minerals that intensively nourish and regenerate the skin. It absorbs perfectly without leaving a greasy film — making it ideal for whole-body care, including dry, flaky and atopic skin. It has soothing and anti-inflammatory properties, strengthens the hydrolipid barrier and improves skin elasticity, reducing stretch marks and fine lines. Ideal for massage, at-home body care and products for sensitive and baby skin — hypoallergenic and safe.

A complex of tri- and tetra-peptides that strengthens collagen I, III, IV, VII and XVII (DEJ collagen — the dermal-epidermal junction).

Telosense Active

Telosense Active

Telosense Active is a prime example of advanced longevity skincare — an ingredient that protects telomeres, the ends of chromosomes that shorten with every cell division, driving cellular ageing (senescence). It activates the enzyme telomerase, which helps maintain proper telomere length in skin fibroblasts, slowing the ageing process at the DNA level. As a result, the skin retains its youthful functionality for longer: the production of collagen, elastin, hyaluronic acid and lipids. Regular use has been clinically proven to improve skin density and firmness and to reduce all signs of chronological ageing. It is one of the key ingredients of Christina's modern Muse Red Line — dedicated to skin longevity.

Tranexamic Acid

Tranexamic Acid

Tranexamic acid is a synthetic analogue of the amino acid lysine, originally used in medicine as a drug to inhibit bleeding, which has found a breakthrough application in aesthetic dermatology. It works by inhibiting the plasminogen pathway in melanocytes, which is responsible for melanin overproduction after UV exposure. It effectively reduces melasma, chloasma (pregnancy-related discolouration), hormonal and post-inflammatory hyperpigmentation (PIH) — often where other brightening ingredients fail. It also acts anti-inflammatorily, so it works well in caring for skin with broken capillaries and a tendency to redness. Recommended for skin with hard-to-treat discolouration — a key active ingredient in Christina's Illustrious line.

Tremella Mushroom Extract

Tremella Fuciformis Extract

Tremella mushroom extract (Tremella Fuciformis), also called "snow ear" or "plant-based hyaluronic acid", is a valuable skincare ingredient from Chinese medicine, used for over 600 years. The natural polysaccharides it contains can hold water up to 500 times their own weight, surpassing even hyaluronic acid. Tremella's molecules, however, are smaller than HA, so they penetrate the skin more easily and retain moisture longer in its deeper layers. It also contains natural antioxidants and beta-glucans, which strengthen the skin's protective barrier and counter oxidative stress. Ideal for dehydrated, mature skin and for anyone seeking a natural, bio-alternative to synthetic hyaluronic acid.

Tri-Luronic Acid

Tri-Luronic Acid

Tri-Luronic Acid is a patented formula combining three forms of hyaluronic acid of different molecular weights — low, medium and high. As a result, its hydrating mechanism works synergistically on three levels at once: the high-molecular-weight form creates a protective film on the skin's surface, the medium-molecular-weight form hydrates the intermediate layers, and the low-molecular-weight form penetrates deeply, filling wrinkles from within. The effect is multidimensional hydration lasting up to 24 hours, along with a significant improvement in skin firmness. It has been clinically proven to increase hydration levels by 250% in just 2 weeks of use. An ideal ingredient for dehydrated, mature skin with wrinkles and signs of a dry, dull appearance.

An advanced UV filter (UVA+UVB) with a high protection factor. It does not negatively affect hydration or antioxidants — allowing formulas to retain their full biological activity.

A biomimetic peptide that stimulates the production of collagen I and III, fibronectin, elastin and laminin.

Vectorized Hyaluronic Acid

Vectorized Hyaluronic Acid

Vectorized hyaluronic acid is a patented technology in which hyaluronic acid molecules are additionally "packaged" in lipid carriers, allowing them to cross the corneal barrier of the epidermis. Unlike classic hyaluronic acid, which works mainly on the surface, the vectorized form penetrates the deeper layers of the skin — all the way to the granular layer. There it releases active molecules that intensively moisturize, fill wrinkles from within, and strengthen the deep structure of the skin. The result is an immediately visible fuller, smoother complexion and long-lasting improvement in firmness. Ideal for the care of mature, dehydrated skin and skin with visible expression lines.

Vitamin C

Ascorbic Acid (Vitamin C)

Vitamin C (ascorbic acid) is a water-soluble antioxidant essential to humans, regarded in cosmetics as the gold standard of brightening and anti-aging protection. It performs multiple functions: it strongly neutralizes free radicals, is an essential cofactor in collagen synthesis, inhibits melanin production in melanocytes and strengthens the action of UV filters. It has been clinically proven that, used regularly, it reduces wrinkles, evens out skin tone, brightens hyperpigmentation and restores a youthful glow to the complexion. The most effective forms are L-ascorbic acid (the strongest but unstable) and stable derivatives: Ascorbyl Glucoside, tetrahexyldecyl ascorbate (THD) and magnesium ascorbyl phosphate. Ideal in the care of all skin types, especially dull, tired skin with photoaging and hyperpigmentation — best applied in the morning before an SPF cream.

Vitamin E

Tocopherol

Vitamin E (tocopherol) is one of the most important vitamins in skincare — a powerful fat-soluble antioxidant that protects the cells' lipid membranes from peroxidation. It neutralises free radicals generated by UV exposure, air pollution and intracellular metabolism, thereby slowing photoaging processes. It strengthens the skin's lipid barrier, improves its elasticity and its ability to retain moisture. It works synergistically with vitamin C and ferulic acid — their combination significantly enhances photoprotective action. Ideal in anti-aging products for all skin types, especially tired, dull skin exposed to external factors.

Zinc

Zinc PCA

Zinc PCA (the zinc ester of pyrrolidone carboxylic acid) is a versatile cosmetic ingredient combining the mineral zinc with the skin's natural moisturising factor (NMF). It works on multiple fronts for oily and problematic skin — it regulates sebaceous gland activity by inhibiting 5-alpha-reductase, the enzyme responsible for sebum overproduction. It has strong antibacterial and anti-inflammatory properties, helping heal acne lesions and prevent new ones from forming. It also supports epidermal regeneration and strengthens the skin's hydrolipid barrier. An ideal ingredient for caring for oily, combination and acne-prone skin, as well as skin with enlarged pores and a tendency to shine.
