Pentasodium Tetracarboxymethyl Hexanoyl Dipeptide-12

Pentasodium tetracarboxymethyl hexanoyl dipeptide-12 is a modified peptide—a small chain of amino acids—that has been chemically engineered to enhance its stability and skin-conditioning properties. The ingredient combines a peptide structure with additional carboxylic acid groups, which help it function as a humectant and skin conditioner in formulations.In skincare products, this ingredient is primarily used to support the skin's hydration and overall condition. It works at a molecular level to help maintain moisture and support the skin's natural barrier function.

This peptide derivative functions primarily as a humectant, which means it has an affinity for water molecules and helps draw moisture into the outer layers of the skin. Its structure allows it to bind water effectively and hold it within the skin, supporting hydration levels throughout the day.Additionally, peptides in skincare are thought to interact with the skin in ways that support natural conditioning processes. The carboxylated structure of this particular ingredient may enhance its ability to support the skin's natural moisturising factors and overall barrier health.

This ingredient is typically used as part of a broader skincare formulation rather than as a standalone treatment. It works well in serums, moisturisers, and hydrating products. For best results, apply to clean skin before heavier creams or oils, allowing it to absorb fully. There is no need to use it more frequently than your regular skincare routine—daily use as part of a moisturiser or serum is standard.

This ingredient is generally well-tolerated and is considered safe for use in cosmetics at approved concentrations. No significant safety concerns have been widely reported, though as with any skincare ingredient, patch testing is advisable if you have very reactive skin.
