Prescription strengthCompounded — not FDA-approved
GHK-Cu
Topical — nightly cream
A copper peptide cream a provider may add to a skin routine for texture and skin quality — gentler than retinoids, and usable alongside them.
A compounded cosmetic-grade peptide cream. It is not an FDA-approved drug, and we don't describe it as one.
Adding to your plan doesn't order anything and doesn't charge you — it tells the provider what you're hoping to discuss.
About 5 minutes. A licensed provider reviews your health and prescribes ghk-cu only if it's right for you — there is no checkout here, and that's deliberate.
How it works
What it actually does
GHK-Cu is a small copper-binding peptide found naturally in human plasma, where levels decline with age. Applied topically, it delivers copper — a cofactor skin uses in collagen and elastin production — and has been studied for its role in skin remodeling. The honest framing: the mechanism is real biochemistry, the strongest evidence is laboratory and small-study work, and it is not a substitute for the prescription actives with decades of trial data behind them.
See the full mechanism, step by stepA provider may consider it if
- You want a supporting active alongside tretinoin, not instead of it
- Retinoids irritate your skin and your provider wants a gentler adjunct
- You care about texture and skin quality more than acne
It won't be prescribed if
- Anyone expecting retinoid-level results — the evidence base is smaller and we say so
- Broken or infected skin without provider review
- Copper sensitivity, which is rare but real
These are the same checks the visit runs. If one applies, the visit will tell you plainly rather than take your money.
What to expect
Realistically, month by month
Weeks 1–4
No adjustment period to speak of — this is one of the reasons providers reach for it when retinoids are too harsh.
Months 2–3
The earliest point where texture change is typically assessed, alongside whatever else is in the routine.
Safety, stated up front
Side effects, before you decide
Generally well tolerated. Mild redness or itching at the application site can occur; a faint blue tint to the cream is the copper and is normal. Discontinue and message your provider if irritation persists.

Questions
Asked honestly, answered honestly
Is this a drug?
No. It's a cosmetic-grade peptide prepared by a compounding pharmacy. That's exactly why it sits alongside prescription treatment in a routine rather than replacing it.
