The authors reported a 55.8% reduction in facial wrinkle volume and a 32.8% reduction in wrinkle depth compared with control serum, alongside in vitro evidence that GHK-Cu increased both collagen and elastin production in human dermal fibroblasts at concentrations as low as 0.01 nM [4]
According to a study by the Journal of Applied Physiology, BPC-157 has been shown to promote tendon healing
However, as you age, your natural production of GHK-Cu declines
Stye (Hordeolum) A stye is an acute, localized infection of an eyelid gland, often presenting as a painful, red bump near the lid margin
