GHK-Cu has attracted considerable attention in the fields of skincare, cosmetic science, and research into skin regeneration. The name refers to a copper-binding peptide made from three amino acids: glycine, histidine, and lysine. When this peptide binds with copper ions, it forms the copper complex commonly known as GHK-Cu. Researchers have investigated Ghk cu for its potential role in supporting skin repair, collagen production, and healthy-looking skin.
As interest in peptide-based skincare continues to grow, GHK-Cu has become a popular ingredient in serums, creams, and other cosmetic formulations. Understanding what GHK-Cu is and what research suggests about it can help consumers make more informed decisions about products containing this ingredient.
What Is GHK-Cu?
GHK-Cu is a naturally occurring copper peptide. GHK stands for glycyl-L-histidyl-L-lysine, which describes the three-amino-acid structure of the peptide Ghk cu. The “Cu” represents copper, because the peptide has an ability to bind copper ions.
The compound is naturally present in the human body and has been detected in biological fluids and tissues. However, levels of G
