The high affinity of GHK for copper(II) ions (binding constant K = 10^16.44 M) ensures that copper is transported in a bound, controlled form rather than as a free ion causing oxidative stress
The formula relies on a balanced AHA blend of glycolic, lactic, pyruvic, and tartaric acids to loosen dead skin cells around rough patches, KP-prone areas, and uneven texture
While animal and in vitro studies have examined its activity, large-scale human clinical trials are limited, and its full safety and efficacy profile has not been established
On the 15th day, the tissue in the wound area of the GHK and RGD-GHK groups exhibited a deeper blue color compared to other two groups, indicating higher collagen levels (Figure 7H)
