System Verdict
Solid sunscreen formula, but the minimalist INCI and truncated ingredient list make it hard to call this exceptional. The efficacy score is driven mainly by a strong modern UV filter system: Diethylamino Hydroxybenzoyl Hexyl Benzoate covers UVA, Ethylhexyl Triazone covers UVB, and Methylene Bis-Benzotriazolyl Tetramethylbutylphenol adds broad-spectrum support. Niacinamide may add a small secondary benefit, but at this low apparent position it is not the reason to buy this; the formula’s real job is sun protection, not treatment-level skincare. Because the provided INCI is unusually short and ends abruptly at Coco-Caprylate/, I cannot verify formula completeness, so the score is held below the level I would give a fully transparent, well-substantiated sunscreen.
