System Verdict
This is an excellent high‑protection sunscreen with elite filters but a drying, alcohol‑heavy base that makes it great for oily skin and a bad idea for compromised barriers. Efficacy is high because it uses multiple modern, photostable filters (Mexoryl SX/XL, avobenzone, ethylhexyl triazone, titanium dioxide) in a film‑forming network, plus vitamin E for antioxidant support, so UV coverage and real‑world durability are S Tier; however, the formula is built around high denatured alcohol and mattifying powders with minimal barrier support, so I cap the efficacy score slightly below “clinically optimal” and dock safety for irritation risk on dry, sensitive, or rosacea‑prone skin.
