What is it?
Sericin is a natural protein derived from silk, specifically from the cocoon of the silkworm (Bombyx mori). It is known for its excellent moisturizing and film-forming properties, which can protect and smooth the skin. In skincare, sericin is valued for its ability to contribute to skin hydration and elasticity, and provide a protective barrier on the skin's surface.
Where does it come from?
Sericin is obtained from silk cocoons produced by silkworms. During the silk manufacturing process, sericin is separated from fibroin, the primary protein in silk fibers, through a process called degumming. This process allows sericin to be extracted and purified for use in various skincare formulations.
