Components

GHK-CuModerate evidence Matrixyl (Pal-KTTKS)Limited evidence ArgirelineLimited evidence

Rationale

The topical triad of cosmetic dermatology: GHK-Cu (remodeling, copper), Matrixyl (collagen I/III signal), Argireline ("botox-like" relaxation of muscle contraction). Different mechanisms — matrix support, signaling and dynamic wrinkles.

Evidence level

All three have cosmetic clinical trials (small, sponsor-funded, but real): measurable improvements in texture and wrinkle depth over 8–12 weeks.

Caution

Concentrations in retail serums are often below studied levels; copper peptides can irritate sensitive skin at high doses.
