Silk Extract
What is Silk Extract?
Silk extract comes from the natural proteins found in silkworm cocoons, primarily fibroin and sericin from Bombyx mori. These proteins are hydrolyzed into smaller peptides for better solubility in cosmetic formulations. Commonly used in moisturizers, serums, and creams, it functions as a humectant by drawing moisture to the skin, an emollient to soften the surface, and a film-former to create a protective barrier that locks in hydration. This helps maintain the skin's natural barrier while enhancing its texture. In products, it appears as a fine powder or liquid extract, compatible with water-based and emulsion systems. Its amino acid composition, rich in serine and glycine, supports skin's protein structure, contributing to suppleness without heaviness.
