What Is GHK-Cu?

GHK-Cu (glycyl-L-histidyl-L-lysine copper) is one of the most extensively studied cosmetic peptides. It belongs to a class of compounds known as carrier peptides, which bind to copper ions and help transport essential trace elements involved in normal cellular functions.

Naturally occurring within the human body, GHK-Cu has attracted significant scientific interest due to its potential role in regeneration and repair. Research has associated GHK-Cu with improvements in skin firmness, elasticity, texture, and the appearance of fine lines and wrinkles. Studies have also explored its antioxidant, anti-inflammatory, and wound-healing properties.

Why Is GHK-Cu Popular in Skincare?

GHK-Cu is commonly included in anti-aging skincare products because of its ability to support processes associated with skin renewal. Research suggests that GHK-Cu may help support collagen and elastin production while also helping protect skin from environmental stressors and UV-related damage. Because of its broad range of studied benefits, GHK-Cu has become one of the most recognized peptide ingredients used in modern cosmetic formulations.
