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.
LIFTING EFFECTA 35% increase in hydration in 14 days (corneometer, n=25). Antioxidant activity 2.5x higher by ORAC than vitamin E (Aramwit et al., 2010).
Forms a cationic protective film that binds to keratin. Its 18 amino acids (mainly serine, threonine) act as a natural NMF, retaining moisture in the stratum corneum.
