Copper peptide (GHK-Cu) is a bioactive compound with both medical and cosmetic value. It was first discovered in 1973 by American biologist and chemist Dr. Loren Pickart. Essentially, it is a tripeptide composed of three amino acids—glycine, histidine, and lysine—combined with a divalent copper ion. Since copper ions in aqueous solution appear blue, this structure was named “blue copper peptide.”
As we age, the concentration of copper peptides in our blood and saliva gradually decreases. Copper itself is a vital mineral that plays an essential role in iron absorption, tissue repair, and the activation of numerous enzymes. By carrying copper ions, GHK-Cu demonstrates remarkable reparative and protective abilities. Studies have shown that it can penetrate into the dermis, stimulating the production of collagen and elastin. This not only improves skin elasticity and smooths fine lines but also provides significant restorative effects for sensitive or damaged skin. For this reason, it has become a widely used ingredient in premium anti-aging skincare products and is regarded as a key molecule in delaying skin aging.
Beyond skincare, GHK-Cu also shows outstanding benefits for hair health. It activates hair follicle growth factors, promotes scalp metabolism, strengthens the roots, and extends the hair growth cycle. Therefore, it is frequently found in hair growth formulations and scalp care products. From a medical perspective, it has demonstrated anti-inflammatory effects, wound-healing potential, and has even attracted research interest in cancer-related studies.
In summary, GHK-Cu copper peptide represents a remarkable transformation of scientific discovery into practical applications. Combining skin repair, anti-aging, and hair-strengthening benefits, it has reshaped the formulations of both skincare and haircare products while increasingly becoming a star ingredient in medical research.
