Sericin · Hydrolyzed SericinHydrator
A silk-derived protein used as a film-forming humectant that smooths and conditions the surface.
What it does
Sericin is a protein from silk. It binds water and forms a light, smooth film on the skin surface, giving a conditioned, softer feel, so it is used as a humectant and conditioning agent. It is a conditioning-and-film ingredient rather than a skin active.
