Nonapeptide-1- 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.
- Nonapeptide-1 is a synthetic 9-amino acid peptide that inhibits melanin production by blocking α-MSH (alpha-melanocyte stimulating hormone) receptor binding. Used in cosmetic formulations for skin lightening and evening skin tone, it is particularly effective for UV-induced and hormonal hyperpigmentation.
