Skin Protectant, Lipopeptide

Palmitoyl Isoleucine

Palmitoyl Isoleucine is a lipopeptide (lipoamino acid) formed by combining palmitic acid with the essential amino acid isoleucine. This structure allows it to integrate into the skin's lipid matrix, reinforcing the barrier between skin cells. It is used in anti-ageing, firming, and barrier-repair formulations for its skin-protecting and conditioning properties.
