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.
SMOOTHINGA 24% increase in skin smoothness over 4 weeks (profilometry, n=28). Hypoallergenicity confirmed in patch tests (Cosmetics Europe).
Low-molecular-weight fibroin peptides (5-30 kDa) penetrate microcracks in the epidermis. The amino acids serine and alanine act as a natural NMF.
