Performance Scores

SPF Level
An SPF rating of 50+ falls into the 'Very high' protection tier, suitable for extreme exposure and supported by the primary mineral filter.
Broad Spectrum
Zinc Oxide provides continuous broad-spectrum coverage spanning both UVA II and UVA I ranges, though a single-filter system does not reach the overlapping robustness of a multi-filter tier 5.
Sweat Resistance
The product lacks a formal water resistance claim but contains a heavy silicone infrastructure that provides unverified, baseline water repellency.
Visible Light
The formulation completely lacks iron oxides or dedicated tinting agents necessary to meaningfully attenuate visible light and high-energy visible (blue) light.
Irritation Risk
Formulated entirely with non-irritating mineral UV filters, inert silicones, and emollients without any known harsh surfactants or chemical irritants.
Pore Clogging
The formulation contains isostearic acid at a high estimated concentration, which is widely recognized as a highly comedogenic ingredient.
White Cast
Relies entirely on zinc oxide as the sole UV filter to achieve SPF 50+, which typically requires a high concentration (>20%) leading to visible cast.
