GHK-Cu (Glycyl-L-Histidyl-L-Lysine Copper) is a naturally occurring copper-binding peptide found in the human body, recognised for its powerful regenerative and skin-repair signalling properties. It plays an important role in wound healing, collagen support, tissue remodelling, and maintaining healthy skin function, helping improve firmness, elasticity, and overall skin quality.
GHK-Cu is also known for its antioxidant and anti-inflammatory activity, helping calm visible irritation while protecting the skin from environmental stress. However, due to its molecular structure, GHK-Cu can be difficult to effectively deliver into the skin without disrupting skin integrity. This is why advanced delivery systems, such as spicules, are used to create temporary micro-pathways that support deeper penetration and more efficient delivery of the peptide into the skin.
