Copper Tripeptide-1 Palmitamide

Copper Tripeptide-1 Palmitamide is a synthetic peptide compound that combines three amino acids with a copper ion and a fatty acid chain (palmitate). Peptides are short chains of amino acids that can penetrate the outer layers of skin, and the addition of copper and the palmitate moiety is intended to enhance stability and skin affinity.In skincare formulations, this ingredient functions as an antioxidant, helping to neutralise free radicals that can damage skin cells. It also has skin-conditioning properties, meaning it can improve the feel and appearance of skin texture.

The copper ion in this complex is believed to function as a cofactor for enzymes involved in skin renewal and collagen cross-linking, whilst the peptide portion may enhance penetration and the antioxidant effect. The palmitate fatty acid chain helps anchor the ingredient into the skin barrier, potentially improving retention.As an antioxidant, the copper component can donate electrons to neutralise unpaired electrons in free radicals, preventing them from causing oxidative damage to skin cells and lipids.

This ingredient is typically found in serums, moisturisers, and treatment products. Use as directed by the product instructions, generally once or twice daily. It works well alongside other antioxidants such as vitamin C or niacinamide, and is compatible with most skincare routines. Allow products to dry fully before layering other treatments.

Generally well-tolerated by most skin types. As with all peptides, those with copper sensitivity should avoid. Patch test if you have very sensitive or reactive skin.
