GHK-Cu is a tripeptide — three amino acids carrying a copper ion — first isolated from human plasma in 1973. Your skin uses it as a repair signal. The problem: you make less of it every year.
GHK-Cu binds skin receptors that trigger collagen and elastin synthesis — the scaffolding that keeps skin firm.
SNAP-8 targets the look of expression lines — visibly smoothing the creases that repeated expressions leave around the forehead and eyes.
Multi-weight hyaluronic acid plumps immediately while panthenol keeps the barrier calm — so the actives stay comfortable.
Independent consumer self-assessment · 124 participants · twice daily for 8 weeks. Firmness and fine-line figures measured at week 8; hydration reported from first use.
“I bought it for the forehead lines. I kept it because my skin just looks… awake. The blue is real, it’s not dye — I checked.”
“45, skeptical, spreadsheet guy. Took weekly photos under the same light. Week 8 vs week 0 is not subtle. Subscribed.”
“Docked a star because I wanted overnight magic and it took five weeks to show. But it layers under sunscreen perfectly, no pilling, no sting around the eyes — and the firmness along my jaw is genuinely different.”
Two pumps, morning and night, on clean skin. One bottle runs about two months — the length of one full protocol.
