A genuinely high-performance sunscreen undermined by a heavy alcohol load and added fragrance.

READ MORE
The efficacy score is 4.6/5 because the formula uses a sophisticated, photostable multi-filter system covering UVB, UVA, and ultra-long UVA, with film-forming polymers supporting uniform wear and water resistance; glycerin is present for modest hydration, but the formula does not earn a near-perfect score because the high second-position denatured alcohol and fragrance can compromise tolerability, while the antioxidant and moisturizing support are secondary rather than treatment-level benefits. The safety score is reduced primarily for alcohol denat. near the top and parfum; the score is not reduced for sunscreen filters themselves.
