In another trial, 41 women with mild to advanced photodamage applied GHK-Cu eye cream for three months and saw reduced lines and wrinkles, improved skin density, and increased skin thickness better than both placebo and vitamin K cream.3 Similarly, in a pilot study investigating copper tripeptide topicals for aged skin, experts found that they increased skin thickness and elasticity, improved hydration, and boosted collagen synthesis.3 Hair growth In a review from 2023, experts explained that GHK-Cu may promote hair growth in a few different ways
Together, they provide a complementary approach for studies focused on healing and regenerative pathways
