That copper-bound structure is one reason GHK-Cu has become so interesting in skin and hair research
According to a 2018 review, GHK-Cu as a cosmetic ingredient has demonstrated the ability to:3 Tighten loose skin Reverse age-related skin thinning Repair the skins protective barrier proteins Improve skin firmness and elasticity Reduce the appearance of fine lines and wrinkles Smooth rough skin Stimulate wound healing Lessen the appearance of photodamage (sun damage), hyperpigmentation, skin spots, lesions, and more Reduce inflammation and damage from free radicals Increase hair growth and thickness Additionally, in research from 2015, the authors noted that GHK-Cu may be able to stimulate collagen, regulate the skin remodeling process, attract immune cells to the site of an injury, and restore replicative vitality to fibroblasts (a cell that helps form connective tissue) in patients whove undergone radiation therapy for cancer.2 6 GHK-Cu isnt limited to topical/cosmetic forms, however

Fortunately, oral supplementation plays a crucial role in overcoming this deficiency and can usually get things back on track
Peer-reviewed studies demonstrate that GHK-Cu can: Stimulate fibroblast proliferation and collagen synthesis Increase glycosaminoglycan production Support wound contraction and remodeling Reduce oxidative stress and inflammation A major review published in the International Journal of Molecular Sciences describes GHK-Cu as a compound that resets gene expression to a healthier state, influencing over 4,000 human genes involved in tissue repair and anti-inflammatory processes
The immune system gets activated and starts treating healthy cells as bacteria or viruses, trying to fight them off and kill them
