Decapeptide-12- Summary
- Collagen peptides are short-chain amino acid sequences produced by enzymatic hydrolysis of whole collagen (typically bovine or marine). They serve as bioactive signals that stimulate fibroblasts and chondrocytes to produce new collagen, elastin, and cartilage matrix, supporting skin, joint, bone, and gut health.
- Decapeptide-12 is a synthetic 10-amino acid peptide developed for skin brightening and depigmentation. It selectively inhibits tyrosinase activity and downstream melanogenesis pathways, reducing hyperpigmentation, dark spots, and uneven skin tone without the irritation associated with hydroquinone.
