Science & Benefits

A fatty acid derived from castor oil that has been shown to down-regulate the production of sebum and inhibit the UV-induced signals that lead to pore enlargement. While technically a fatty acid (Comedogenic 1), its clinical benefits for skin texture and pore refining make it a 'Good' rating. It is best used in oil-free formulations where its texture-modifying properties can be maximized without added occlusivity.
