About
A palmitic-acid-conjugated tripeptide for skin conditioning. Lipidation improves skin penetration; independent safety data is limited.
Palmitoyl Tripeptide-99 is a tripeptide N-terminally conjugated to a palmitic acid (C16) chain, formulated for cosmetic skin-conditioning use. The palmitoyl moiety improves stratum corneum penetration relative to unmodified peptides — a strategy popularized by Matrixyl-type peptides. Used at parts-per-million levels in serums and creams. No independent CIR or SCCS review of this specific INCI is available; efficacy claims rely on supplier studies. The class as a whole has a long market history with low irritation reports. Listed in EU CosIng. Conservative tier: yellow with low evidence.
