Firmness / AgingBrightening
INCI: Decapeptide-4
In short · TL;DR
Category
Peptides
Effect
Brightening, melanin production suppression
Concentration
0.001-0.01%
Effect
Brightening, melanin production suppression
Mechanism
Alpha-MSH (melanocyte-stimulating hormone) antagonist peptide
Typical concentration
0.001-0.01%
Onset
Brightening: 8-12 weeks
Cautions
Decapeptide-12 (Lumixyl, a tyrosinase inhibitor) is the brightening decapeptide with established clinical use. The 'Decapeptide-4 = brightening via α-MSH antagonism' claim here requires verification of both ingredient identity and mechanism from primary sources (possible confusion with the Nonapeptide-1 mechanism).
