GHK-Cu foam 5mg/ml

GHK-Cu Foam 5mg/mL is a topical formulation of the naturally occurring copper peptide GHK-Cu (glycyl-L-histidyl-L-lysine complexed with copper), commonly used in dermatologic and hair restoration research. This tripeptide is found in human plasma, saliva, and tissues, where it functions as a signaling molecule involved in tissue repair and regeneration. When delivered as a foam, GHK-Cu allows for enhanced scalp or skin absorption and even distribution, making it particularly useful for hair growth protocols and cosmetic skin applications. Mechanistically, GHK-Cu binds copper ions and activates pathways involved in collagen and elastin synthesis, angiogenesis (formation of new blood vessels), and anti-inflammatory signaling. It has been shown to upregulate growth factors and modulate thousands of genes associated with tissue remodeling and repair. In hair applications, topical GHK-Cu has demonstrated the ability to stimulate hair follicles, increase follicle size, and prolong the anagen (growth) phase, contributing to improved hair density in some studies. Additionally, its antioxidant properties support scalp health by reducing oxidative stress and inflammation, both of which are implicated in hair thinning and aging
