Miller TR, Wagner JD, Baack BR, et al. Archives of Facial Plastic Surgery 2006;8:252-259.
What it found
GHK-Cu products did not shorten post-laser redness and did not improve wrinkles or skin quality on objective or blinded assessment compared with the regimen without GHK-Cu. Patient-reported satisfaction with skin quality was higher with GHK-Cu.
Limitations
Only 13 patients completed. Cosmetic products applied to the skin, not injection.
