Sericin
Sericin is a natural protein produced by silkworms, specifically from the cocoons of the Bombyx mori species. It acts as a protective layer, helping to keep the silk fibers together and providing a barrier against environmental factors. Sericin is water-soluble and can be extracted from silk during the processing of silk fibers.
In addition to its role in silk production, sericin has gained attention in the cosmetic and skincare industries. It is known for its moisturizing and skin-soothing properties, making it a popular ingredient in various beauty products. Its ability to form a protective film on the skin helps retain moisture and improve overall skin texture.
