What's Inside

The actives, and why.

Copper Tripeptide-1 (GHK-Cu), 99% purity
—
A naturally occurring copper-bound peptide studied for over five decades for its role in supporting collagen and elastin production, firming aging skin, and supporting the skin's natural renewal processes.

Add 1g of GHK-Cu powder to 30ml of your chosen base (HYDRA BASE or BARRIER BASE) for a 3% concentration. For a milder formula, use 0.5g per 30ml for 1.5%. Mix thoroughly using a clean mixing instrument or rod. Mix until the powder is fully dissolved and the formula turns a uniform deep blue. Store in a cool, dark place. Refrigeration strongly recommended — copper peptides are sensitive to heat and light. For cosmetic formulation use only. Not for use on broken or irritated skin. Always patch test before first use. If irritation occurs, discontinue use.
