System Verdict
This is a high-performance, high-irritation-risk sport sunscreen: excellent UV coverage and water resistance, but loaded with denatured alcohol, oxybenzone, and added fragrance. The efficacy score is driven by a robust mix of chemical UV filters (avobenzone, octocrylene, homosalate, octisalate, oxybenzone) plus film-formers that create water-resistant protection, not by the minor antioxidants or aloe which are present mainly for marketing and stability rather than meaningful skin benefits; safety is dragged down by the heavy use of drying alcohol, a sensitizing filter (oxybenzone), and fragrance in a spray meant for frequent, full-body application.
