What is GHK-Cu?
GHK is a tripeptide made from glycine, histidine and lysine; Cu is copper bound to that peptide. On a cosmetic ingredient list, look for Copper Tripeptide-1. It is an ingredient identity, not a promise that every formula performs alike.
What it does for skin’s look and feel
A GHK-Cu routine focuses on firmer-looking, smoother-looking skin and a comfortable, hydrated feel. Assess the whole formula and your own experience rather than assuming the ingredient name guarantees a particular outcome.
Why wear it as hydrogel?
A serum spreads as a thin leave-on layer; hydrogel holds a formula against skin during a dedicated masking session. Smooth the gel closely to the contours so it stays on comfortably. Wear it until it turns transparent, so you know your skin has absorbed the essence. Then remove and gently massage the remaining essence into the skin. The colour change is not a measurement of ingredient absorption.
Inside our best seller
Night ☾ GHK-Cu Copper Peptide Hydrogel Mask combines Copper Tripeptide-1, 6 supporting peptides, glycerin and allantoin. The formula is designed for skin that feels supple and looks smoother. Each box contains 5 masks, 34 g each.
How to use the GHK-Cu mask
Cleanse and apply toner, remove the backing and smooth the mask onto your face. Wear it until it turns transparent, so you know your skin has absorbed the essence. Then remove and gently massage the remaining essence into skin. Follow with moisturiser as needed, then sleep on the massaged-in essence. Use SPF in your daytime routine.
- Start with clean skin rather than makeup or sunscreen.
- Smooth both portions into contact without stretching the gel.
- Wear it until it turns transparent.
Fit it around serums, retinol and vitamin C
Keep the mask session simple. A peptide serum can fit on non-mask mornings; more layers are not automatically better. If you use retinol at night or vitamin C in the morning, separate new additions at first so you can judge comfort. Follow each product’s directions and finish daytime routines with SPF.
Who it suits
Consider it if you want a firmer-looking finish, a smoother makeup base or a hydration-focused pause. Patch test before first use, especially if your skin is reactive. Do not apply to broken or irritated skin; remove if discomfort develops.
What to expect over 30 days
After a session, notice how skin feels and how smoothly moisturiser sits. Over a month, keep lighting and camera distance consistent if you compare photos. Results vary; a smoother-looking finish is not a guarantee that visible lines disappear. One box can cover 5 evenings over two weeks without making daily use a requirement.
