Sericin is a protein derived from silk, commonly used in cosmetics for its unique skincare benefits. Extracted from silkworm cocoons during the silk production process, sericin possesses excellent moisture retention properties. In skincare formulations, it acts as a natural humectant, promoting hydration and imparting a smooth, silky texture to the skin. Sericin is renowned for its ability to enhance skin elasticity, reduce the appearance of fine lines, and provide a protective barrier. Its gentle, non-irritating nature makes it suitable for sensitive skin products, contributing to a luxurious and nourishing experience in various cosmetic applications.

Origin
Sericin is extracted during the degumming process of silk production. Cocoons are boiled to remove the outer silk fibroin, leaving sericin behind. Subsequent purification steps may be employed to isolate and refine sericin. In its raw form, it appears as a yellowish-brown liquid.
