System Verdict
Brutally effective UV armor in a cosmetically elegant but alcohol-heavy, fragranced base that oily skins will love and sensitive, dry, or acne-prone skins may hate. I’m scoring efficacy high because this packs an S Tier, photostable filter arsenal (Mexoryl SX/XL, Bemotrizinol, Tinosorb S, Avobenzone, multiple salicylates) in proven concentrations, delivering robust UVA/UVB coverage, but deducting slightly for the very high alcohol content and reliance on cosmetic feel over barrier support, which limit comfort and tolerability rather than pure protective power.
