System Verdict
Solid sunscreen, but the “moisturizing” claim is doing more marketing than heavy lifting. The UV filter system is strong and well-rounded for UVA/UVB protection, so the efficacy score is high on the sun-protection axis, but the hydration/barrier story is only moderate because the humectants and soothing agents sit mostly mid-to-late INCI, where they are likely below the level needed to materially transform the formula. The presence of fragrant oils also pulls the safety score down from excellent, so this lands in the strong-but-not-flawless A Tier for sunscreen performance rather than a truly top-possible formula.
