Quick answer
GHK-Cu is a copper peptide your skin makes on its own and makes less of every decade after your twenties. Applied as a cream it acts as a signal for the collagen and elastin that keep skin firm and smooth. Published studies of GHK-Cu cream ran about 12 weeks and reported firmer skin, softer looking fine lines and higher skin density. At PepHaus it is a prescription strength cream, one thin layer a day, for $149 per month with the provider review and shipping included.
What GHK-Cu is
GHK-Cu is a tripeptide (glycine, histidine and lysine) bound to a copper ion. It was first identified in human plasma in the 1970s and it shows up in skin, saliva and other tissue. Levels are highest when you are young and drop steadily with age.
In skin, GHK-Cu works as a messenger. It tells cells to rebuild the support structure that thins out over time. That is why it became one of the most studied peptides in skin care.
PepHaus GHK-Cu is compounded for you by a licensed U.S. pharmacy at prescription strength after a provider reviews your answers. It ships ready to use. Nothing to mix, nothing to inject.
What it does for skin
- Collagen and elastin. GHK-Cu signals skin cells to produce the collagen and elastin that keep skin firm and springy.
- Repair. It supports the skin's own repair and remodeling process, which is how it earned its place in wound care research.
- Tone. People use it for uneven tone and sun worn patches on the face and neck.
- Barrier comfort. It is gentle, so most people can use it every day without the peeling and stinging that comes with stronger actives.
GHK-Cu vs retinol vs vitamin C
| GHK-Cu cream | Retinol | Vitamin C serum | |
|---|---|---|---|
| Main job | Firmness, fine lines, density | Cell turnover, fine lines, texture | Brightness, antioxidant protection |
| Feel on skin | Gentle, daily use | Dryness and peeling while skin adjusts | Can sting on sensitive skin |
| When to apply | Morning or night | Night | Morning |
| Use together? | Pairs with both at a different time of day | Pairs with GHK-Cu in the morning | Apply apart from GHK-Cu |
You do not have to pick one. Many routines run vitamin C in the morning and retinol at night, with GHK-Cu on the side of the day that is free. Your provider can map it to your skin.
Who GHK-Cu cream is for
Fine lines are settling in
Around the eyes, the mouth and across the forehead, where makeup has started to sit in the lines.
Skin lost its bounce
Cheeks and jawline that could use more support. Skin that is slower to spring back when you press it.
Tone is uneven
Sun worn patches and tone on the face and neck that used to be more even.
Retinol is too harsh
You want a daily active that does not leave your skin red and flaky.
You hate long routines
One thin layer a day that fits under moisturizer, sunscreen and makeup.
Already on glutathione
Glutathione works from the inside. GHK-Cu works on the surface. Your provider confirms the combination.
What to expect, week by week
Individual results vary. This is the pattern most people describe with daily use.
| When | What people commonly report |
|---|---|
| Week 1 to 2 | Skin feels softer and more comfortable. Some notice a little tingling the first few days. |
| Week 3 to 6 | Smoother texture. Makeup sits better. |
| Week 8 to 12 | Skin looks firmer. Fine lines look softer. This is the window the published studies measured. |
| Month 3 and beyond | Results hold with steady daily use. |
How to use it
- Clean, dry skin. Morning or night, after cleansing.
- A pea sized amount. Enough for the face and neck. Press it in instead of rubbing.
- Layer as usual. Moisturizer, sunscreen and makeup go right over it.
- Space out strong acids and vitamin C. Use them at the other end of the day.
- Stay consistent. Daily use for 8 to 12 weeks is where the change shows.
- Sunscreen every morning. It protects the progress you are building.
Side effects and safety
GHK-Cu is gentle and most people use it every day without trouble. What gets reported:
- Common: mild tingling or a little redness in the first few days, which usually settles.
- Less common: dryness or irritation, more likely when layered at the same time as strong acids.
- Tell your provider about: irritation that does not settle, a known copper sensitivity, or any rash.
GHK-Cu cream is not for use during pregnancy or nursing. A licensed provider reviews your answers before anything is prescribed, and nothing is charged unless you are prescribed.
