Palmitoyl Tripeptide-8 is a synthetic peptide that has the property of reducing UV-induced inflammatory responses, reducing the production of interleukin-1 (IL-1), and promoting the secretion of interleukin-8 (IL-8), thereby helping to relieve and soothe irritated skin. This ingredient can penetrate deep into the surface layer of the skin, regulate the synthesis of skin proteins, repair damaged sensitive skin, and enhance the skin's resistance to irritation. Palmitoyl Tripeptide-8 has passed the safety assessment of the Cosmetic Ingredient Review (CIR) of the United States and has been identified as a safe and effective cosmetic ingredient.
