What it is
Oligopeptide-32 is a laboratory-made chain of a small number of amino acids belonging to the broad family of bioactive peptides used in cosmetics. It is included at low concentrations as a skin-conditioning agent intended to support the appearance of smooth, comfortable skin. In sunscreen products it functions as a supporting care ingredient rather than as a UV filter.
Safety & warnings
Short synthetic peptides used at the low levels typical of cosmetics are generally well tolerated and are not associated with comedogenicity. As with any leave-on ingredient, isolated sensitivity is possible.
Origin & sourcing
Synthetic. Like other numbered cosmetic oligopeptides, it is produced by chemical or biotechnological peptide synthesis rather than extracted from a natural source.
