What it is
This ingredient combines a short two-amino-acid peptide with palmitic acid, a fatty acid that improves the molecule's affinity for the skin surface. It is added to formulas as a conditioning peptide and is often used to support a product's peptide-focused positioning. In sunscreens it appears at low concentrations alongside the primary UV filters.
Safety & warnings
