WKPep®SWMPeptides

WKPep® SWMPeptides is a multifunctional peptide complex targeting multiple pathways to deliver outstanding brightening and spot-reducing effects. It not only competes with α-MSH at its receptor site to inhibit melanin production in melanocytes but also reduces the upstream expression of POMC, α-MSH, interleukins, and other related factors. Compared to conventional brightening agents such as niacinamide and kojic acid, it offers a gentler, safer alternative — with more noticeable and effective results.

INCI Name: Nonapeptide-1, Tetrapeptide-30

Function: Brightening, Spot-removing

Recommended use level: 1~5%
