Ingredients

SPF Filter Complex is the hero active in this formula, delivering targeted results with every application.

UV protection works through two mechanisms: mineral filters (zinc oxide, titanium dioxide) sit on the skin surface and physically reflect UV photons, while chemical filters (such as octinoxate, homosalate) absorb UV energy and convert it to harmless heat. Modern formulations blend both for broad-spectrum coverage that blocks UVA (aging) and UVB (burning) without the heavy, white-cast finish of older sunscreens.
