What it is
GHK-Cu is a copper peptide — a three-amino-acid chain (glycyl-L-histidyl-L-lysine) bound to a copper ion. We prescribe it as a topical cream applied at home in a 4-week program, with or without estradiol added. Nothing is injected. It is used to support skin quality, fine lines, texture, and post-procedure recovery when your provider clears it — as a supportive adjunct to sun protection and your skincare plan, not a replacement for either.
The science — how it works
Peptides are short chains of amino acids, the same building blocks that make up the proteins in your body. Many act as signaling molecules that tell cells what to do.
GHK occurs naturally in human plasma, and its measured levels decline with age. Bound to copper, it has been studied in laboratory models for signaling that increases collagen and elastin production, supports antioxidant defenses, and influences the genes involved in wound healing and tissue remodeling. Copper itself is a required cofactor for enzymes that cross-link collagen.
Estradiol, when added, is included because estrogen receptors in skin are involved in collagen content, thickness, and hydration — a separate pathway from the peptide.
What the evidence shows
GHK-Cu has more human data than most peptides we offer, but the studies are small.
Most of the mechanism work is laboratory and cell-culture research on collagen, elastin, and gene expression.
Small cosmetic studies of copper-peptide creams have reported improvements in fine lines, firmness, and skin texture over weeks to months. Sample sizes are limited and many were industry-sponsored.
There is a long record of topical cosmetic use and generally good tolerability, with irritation as the usual complaint.
Head-to-head trials against established actives such as retinoids are lacking, and GHK-Cu is not FDA-approved as a drug for any skin indication.
What to expect, and when
Skin turnover and collagen remodeling are slow. Texture and hydration changes tend to come first; fine-line and firmness changes, if they come, build over months of consistent use. Four weeks is a starting course, not a full result. Results vary, and sun exposure and smoking work against the same pathways this cream targets.
How we dose it
Both options run 4 weeks. Apply a thin layer nightly, or 2–3 nights a week to start, to clean dry skin on the face, neck, or chest as directed. Build up frequency only as your skin tolerates it.
GHK-Cu Cream
Physician-directed GHK-Cu topical cream. Best for skin quality, fine lines, and texture support, and for post-procedure skin recovery once you are cleared.
GHK-Cu + Estradiol Cream
Adds topical estradiol for crepey texture and collagen-support goals. Requires hormone-safety screening before starting and is not appropriate for everyone.
Every plan includes prescription-based sourcing from a licensed compounding pharmacy, customized application guidance, storage instructions, post-procedure guidance where relevant, and provider-directed follow-up. We reassess at 4 weeks and adjust the plan as needed. Change frequency or add other actives only with your provider.
Important notes
Possible side effects: mild irritation, dryness, redness, or sensitivity, most often in the first two weeks.
Tell us about retinoids, acids, or prescription topicals you use, and any hormone-sensitive history before adding estradiol.
Call us for significant rash, worsening irritation, allergic reaction, or any other concern.
Avoid open wounds and the eye area, use daily sun protection, and store as instructed.
