System Verdict
Solid UV protection in a very mediocre, irritation-prone base — fine for short beach days, not something I’d rely on as a daily face sunscreen. Chemically it does the core job (good UVA/UVB filter combo plus film formers and photostabilizer) so efficacy is decent, but there are zero skin-beneficial actives beyond trace vitamin E and the formula leans heavily on fragrance and sensitizing preservatives, which drags down both sophistication and long-term usability for sensitive or daily wear.
