Alanine/Histidine/Lysine Polypeptide Copper Hcl

Alanine/Histidine/Lysine Polypeptide Copper HCl is a peptide complex that combines three amino acids—alanine, histidine, and lysine—with copper in a chelated form. Peptides are short chains of amino acids that can penetrate the skin's outer layers and communicate with skin cells to influence their behaviour.

In skincare formulations, this ingredient functions as a skin conditioner, meaning it works to improve the texture, feel, and overall condition of the skin surface. The copper component may contribute additional properties, as copper plays a role in collagen synthesis and antioxidant defence within the skin.

The peptide component penetrates the upper layers of the epidermis and can interact with skin cells, potentially signalling them to maintain or improve their structural integrity. Histidine and lysine in particular are amino acids involved in collagen and elastin synthesis, though the extent to which this occurs with topical application remains limited in scope.

The chelated copper is bound to the peptide structure in a form designed to remain stable in formulation whilst allowing the copper to participate in enzymatic reactions that support skin resilience and protection against oxidative stress.

This ingredient is typically found in serums, moisturisers, and targeted treatments. Use as directed on the product label. As with any peptide-containing product, consistency over time is more likely to yield results than sporadic use. It can be layered with other skincare actives, though patch testing is advisable if you have sensitive skin or are using multiple active ingredients.
