System Verdict
High-risk disaster for most skin types—high alcohol content strips barrier and causes irritation despite solid SPF protection. Efficacy score docked to 3.3 for missing listed UV filters (likely proprietary undisclosed), low Tocopherol concentration insufficient for robust antioxidant synergy, and alcohol-heavy base compromising long-term photoprotection; safety slashed to 3.2 due to prominent Alcohol Denat drying/irritating sensitive skin while fragrance-free claim holds[1][3].
