Research Overview
Hexapeptide-9
Hexapeptide-9 appears in scientific and cosmetic literature related to wound repair, cell migration, and extracellular matrix support. The evidence base is smaller than for more established peptides, but it is a real research-backed cosmetic ingredient.
Gamma-MSH
Gamma-MSH has been investigated as part of the broader melanocortin network that regulates pigmentation. Evidence suggests it can contribute to melanocyte signaling, though its cosmetic use remains experimental.
