Synopsis: Nine peptide -1, also known as meliteptide, is a whitening nine peptides containing nine amino acids, mainly used for whitening skin and freckle.

Mechanism of action: Neopeptide-1 is a biomimetic peptide that has a very good match with the MChemicalbookC1 receptor on melanocytes, so it can be used as an antagonist of melanocytotropic hormone, competitively binding to the MC1 receptor, preventing tyrosinase from being further activated to produce melanin.
