Sericin
What Sericin is & what it does
Sericin is a water-soluble protein recovered from silk, where it acts as the natural glue that holds silk fibers together. In cosmetic and sunscreen formulas it functions as a film-forming and skin-conditioning agent, helping to leave a smooth surface feel and support hydration. Because it forms a thin protein film, it can improve the sensory finish of a product on the skin.
What does Sericin do in skincare?
Sericin is a silk protein used as a film-forming and skin-conditioning agent. It helps leave a smooth surface feel and can support the skin's hydration by forming a thin protein film. This makes it useful for improving the sensory finish of lotions and sunscreens.
Is Sericin vegan?
Sericin is obtained from silk produced by silkworms, so it is an animal-derived ingredient and is not considered vegan. Products that contain it would not qualify as vegan for that reason.
Is Sericin safe?
Sericin is a widely used cosmetic protein and is generally regarded as well tolerated when used as intended in topical products. As with any protein-based ingredient, individual sensitivities are possible, so anyone with known allergies should review the full ingredient list.
