AHK-Cu Peptide Powder — Copper Tripeptide-2 · 1g
A concentrated cosmetic copper peptide powder for DIY skincare formulators — the less-common cousin of GHK-Cu, prized by people who blend their own serums and want something beyond the usual.
INCI / active: Copper Tripeptide-2 (AHK-Cu). Size: 1 gram.
What it does: A favourite for the look of firmer, denser, more resilient skin — and, like all copper peptides, it turns your formula a beautiful deep blue.
How to formulate: Water-soluble. Typical cosmetic use rate is 0.5–2% of your finished formula. Dissolve into the water phase or stir into a finished water-based serum until fully clear. Don't combine it in the same layer as direct vitamin C or strong acids. Start low and patch test every new blend.
3rd-party tested, sealed, and shipped from LA. For topical, cosmetic use only — not for injection.
