System Verdict
A competent, hydrating sunscreen with solid UV coverage, but the fragrance components and modest treatment payload keep it from being exceptional. The efficacy score is driven mainly by a conventional broad-spectrum filter system (avobenzone, homosalate, octisalate) plus a supportive emollient/humectant base that should make wear more comfortable; niacinamide, glycerin, sodium hyaluronate, hyaluronic acid, and allantoin add genuine but secondary skin-benefit support. It does not score higher because the formula is still primarily a sunscreen, not a treatment, and the botanical/fragrant oils add sensitivity risk without improving UV performance or delivering meaningful added efficacy.
