Palmitoyl Dipeptide-7 is a synthetic lipopeptide combining palmitic acid with a dipeptide (lysine-threonine), used in cosmetic formulations for its purported skin-conditioning and anti-aging properties, often as part of peptide complexes like Matrixyl. It is thought to support extracellular matrix maintenance and signal skin-renewal processes, though robust independent clinical evidence is limited.

Contact sensitization or allergic reaction | Very rare | Isolated reports; patch testing advised for sensitive individuals. |
