Silk Peptides (Hydrolyzed Silk Fibroin Peptides)
Bioactive peptides from silk fibroin (Bombyx mori). Rich in glycine, alanine, and serine, they form moisture-retaining films while providing amino acid building blocks.
How it works
Form hydrogen-bonded films on skin for moisture retention. Absorbed peptides provide substrates for keratin/collagen synthesis. Exhibit antioxidant and tyrosinase-inhibiting activity.
