Covalent Copper Peptide Firming Serum
GHK-Cu 2% remodeling serum
GHK-Cu tripeptide at a true 2%, the blue serum clinics use to extend the collagen-remodeling window that microneedling and RF treatments open. Copper peptides signal repair pathways that keep fibroblasts building long after the appointment.
Use on non-retinal nights during any remodeling program, or daily as a standalone firming course.
- 2% GHK-Cu copper tripeptide
- Distinctive natural blue - no dye
- Do not layer with direct acids or vitamin C

Good, though give it time
No dramatic overnight change, so temper expectations. By week six the difference in my before photos was obvious enough that two colleagues asked what I had changed.

Does what it claims
Absorbs in seconds and layers cleanly under everything else. The only thing I would change is a larger size option.

We stock it for aftercare now
Bought a single unit to try on myself before recommending it. Patients report the same thing I did: comfortable, no stinging, and the bottle lasts about ten weeks at nightly use.

Four weeks in and it shows
Started twice a week like the protocol says and worked up to four. Texture on my cheeks is visibly smoother and I have had none of the flaking I got from the retinol I used before. The pump doses consistently, which matters at this price.

Layers well with everything
No pilling under sunscreen or makeup, which was my problem with the last two I tried. Sinks in before I have finished the other side of my face.

Finally something my skin tolerates
I have rosacea-prone skin and most actives leave me red for days. This one buffers well, especially layered under a ceramide cream. Slow and steady, but it works.
