Palmitoyl Tripeptide-8 is a synthetic lipopeptide used in cosmetic formulations for its soothing, anti-inflammatory, and skin-repairing properties. It is composed of a tripeptide (three amino acids) attached to a palmitic acid (lipid) chain, which improves its skin penetration and stability.
This peptide helps reduce skin inflammation and sensitivity by regulating inflammatory mediators and calming irritated skin. Because of these properties, it is widely used in products for sensitive skin, anti-redness treatments, and anti-aging formulations.
