Collagen signallinginjectable + topical
GHK-Cu
Three amino acids bound to copper that signal collagen production for hair, skin and nails.
What to expect: Skin texture changes by week 6–8; hair density by month 3.
Evidence: ModerateWhere to start
Fix this first.
Collagen production falls about 1% a year after 25. GHK-Cu signals it back on from the inside while the topical works at the surface — as long as the sun is not undoing it.
Priorities, in order
- Daily SPF 30+ first
- Signal collagen from inside and out
- Give it 12 weeks
Foundations
- SPF daily
- Pause retinoids on GHK-Cu days
- Sleep 7+ hours
Start today — no labs needed
- GHK-Cu topical (no labs needed)

Safety & eligibility
Honest about what this is — and isn't.
Not a substitute for dermatologic care for skin conditions.
Not a fit if you have
- Retinoids with sun exposure
- Copper sensitivity
Your physician will ask
- Using retinoids or high sun exposure?
- Known copper sensitivity?
A licensed, Vero-contracted physician reviews your intake and decides whether to prescribe. Nothing ships without that review.
