Palmitoyl Tetrapeptide-72 Amide

Palmitoyl tetrapeptide-72 amide is a synthetic peptide—a short chain of amino acids—that has been chemically modified with a palmitoyl group (a fatty acid component). This modification allows the peptide to penetrate and interact more effectively with skin cells.In skincare formulations, this ingredient functions primarily as a skin conditioner. It works to improve the texture and feel of the skin by supporting its natural moisturising and barrier-maintenance processes.

Peptides like palmitoyl tetrapeptide-72 amide work by signalling to skin cells to optimise their natural maintenance and conditioning processes. The palmitoyl (fatty acid) component helps the peptide penetrate the outer layers of skin, where it can interact with cells involved in maintaining hydration and barrier integrity.The ingredient appears to support the skin's lipid metabolism—the processes that help maintain the barrier's composition and function—though the precise cellular pathways involved require further investigation.

This ingredient is typically found in serums, moisturisers and barrier-repair products. Use as directed on your product; it generally works well in combination with other hydrating or barrier-support ingredients. Consistent use over several weeks is typically needed to assess any improvements in skin texture or comfort.

Palmitoyl tetrapeptide-72 amide is generally well-tolerated in skincare formulations. As with any new ingredient, perform a patch test first if you have sensitive skin or are prone to reactions.
