Sobre este ingrediente

Water-soluble silk protein extracted from the cocoon of Bombyx mori silkworms. Historically a by-product of fibroin (fiber-grade silk) extraction, sericin's high serine content (~30%) gives it strong film-forming and humectant properties for skincare formulations. Japan's silk industry — concentrated in Gunma, Nagano, and Saitama — has rebuilt around high-grade sericin production since the 2000s, using cocoons from JA Silk and small remaining sericulture cooperatives. Used in moisturisers, hair-care, and increasingly in injectable/wound-care medical applications.
