Sobre este ingrediente

The structural protein of silk (~70-75% of cocoon mass), with hydrolysed forms used in cosmetics and biomedical applications. Distinct from sericin (the gum coating), fibroin's beta-sheet crystal structure gives it superior film-forming and tensile properties; medical-grade fibroin scaffolds are emerging in wound dressings and tissue engineering. Japanese sericulture in Gunma, Nagano, and Saitama supplies cocoon stock; specialty processors hydrolyse fibroin for cosmetic ingredient grades. Often paired with sericin in moisture-and-strengthening positioning.
