What it is
Palmitoyl tripeptide-1 is a three-amino-acid peptide (based on the GHK sequence) joined to palmitic acid to improve its affinity for the skin surface. It is used as a skin-conditioning agent and is frequently paired with other peptides in anti-aging-positioned formulas, including some sunscreens. It is used at very low concentrations.
Safety & warnings
Palmitoyl tripeptide-1 is generally well tolerated at the low levels used in cosmetics and has a good safety record. It is not a recognized fragrance allergen and is not associated with comedogenicity.
Origin & sourcing
Synthetic, made by peptide synthesis and conjugated to a palmitic-acid chain to enhance skin compatibility.
