FIGURE 4 This is complicated because as a polar, charged tripeptide, transport of GSH is significantly inhibited by the blood-brain barrier (BBB), thus limiting effective delivery to brain-resident immune cells such as microglia which are central drivers of neuroinflammatory pathology (Valdovinos-Flores and Gonsebatt, 2012
Due to its small size and unique copper-binding characteristics, GHK may be able to facilitate rapid exchange of copper in the intracellular space

This study is of particular interest because the researchers also paired gene studies with laboratory studies, confirming that changes in gene expression are associated with improved collagen reorganization and fibroblasts function [ 28 ] Further studies confirmed the ability of GHK-Cu to reverse gene expression in COPD back to health [ 29 ]
Despite its advantages, its important to acknowledge GHK-Cus limitations when compared to traditional acne treatments in a research context: Limited Direct Evidence for Active Acne Vulgaris: While it has anti-inflammatory properties, there is currently limited direct clinical evidence specifically demonstrating GHK-Cu as a primary treatment for active acne breakouts (e.g., reducing papules, pustules, or cysts)
