Copper peptides are compounds that consist of a short chain of amino acids (peptides) bound to a copper ion. They are often used in skincare products due to their potential benefits for skin health and anti-aging properties. The most common copper peptide used in skincare is GHK-Cu (glycyl-L-histidyl-L-lysine copper).
Chemical Structure of Copper Peptides:
The chemical structure of GHK-Cu (glycyl-L-histidyl-L-lysine copper) can be represented as follows:
H

H3N—CH—CO—NH—CH—CO—NH—CH2—Cu

H H H
In this structure, H3N represents the amino group (-NH2) of the amino acid glycine, CH represents the methylene group (-CH2-) in various amino acids, CO represents the carbonyl group (-CO-) of the peptide bond, and Cu represents the copper ion (Cu2+).
Physical Properties of Copper Peptides:
Copper peptides are known to have several potential benefits for the skin, including:
- Wound Healing: Copper peptides have been studied for their ability to promote wound healing by stimulating collagen production and angiogenesis (formation of new blood vessels). This can aid in tissue repair and regeneration.
- Antioxidant Properties: Copper peptides have antioxidant properties, which means they can help protect the skin from oxidative stress and damage caused by free radicals.
- Collagen Stimulation: Copper peptides can stimulate the synthesis of collagen, a protein that provides structural support to the skin. This can lead to improved skin firmness and elasticity.
- Anti-Inflammatory Effects: Copper peptides may have anti-inflammatory effects, helping to calm and soothe irritated skin.
- Copper Delivery: Copper is an essential trace element that plays a role in various enzymatic reactions in the body. Copper peptides can help deliver copper to the skin, where it may contribute to these processes.
It’s important to note that while copper peptides have shown promise in various studies, individual results may vary, and not all products containing copper peptides will have the same effects. As with any skincare ingredient, it’s advisable to do a patch test before using a new product and to consult with a dermatologist if you have any concerns or specific skin conditions.
Additionally, the stability and effectiveness of copper peptides in skincare products can be influenced by factors such as pH, concentration, and formulation. Therefore, it’s essential to choose products from reputable brands with proven efficacy and safety.
