What it is
A copper peptide serum: GHK-Cu, the copper complex of the tripeptide glycyl-L-histidyl-L-lysine, in a light water-based serum. The same peptide we supply in the vial, at a fixed concentration, in a base that absorbs in seconds.
How it works
GHK-Cu is taken up by the skin, where it supports collagen and elastin production, hyaluronic acid synthesis and the skin's own antioxidant defences, and helps calm irritation. The serum is thin and absorbs fast, so it layers under a moisturiser or the cream.
What it is for
- Fine lines and loss of firmness
- Uneven tone and texture
- Skin recovery after sun, cold or procedures
- Scalp and hair-density routines
- Daily use, morning or evening, on clean skin
Use and storage
GHK-Cu is a naturally occurring copper peptide with a long record of use in skin care and good skin tolerance in published studies. The product is blue from the copper complex, not from a dye. Avoid the eye area; keep closed, cool and away from light. Not for use on broken skin.
Why this concentration
5 % is the stronger option, for skin that already tolerates copper peptides and wants more per application.
