Decapeptide-18 (CG-Wint) is a WNT10-derived peptide. It possesses WNT10-like activity and exhibits higher stability and skin penetration than natural WNT10. It stimulates the formation of the hair follicle substrate. Decapeptide-18 (CG-Wint) generates new hair by activating β-catenin signaling (β-catenin signaling is a key factor in the differentiation of hair follicle epithelial stem cells into hair keratinocytes).
