System Verdict
Solid, lightweight sunscreen with real UV protection and decent hydration, but the antioxidant/"brightening" extras are mostly garnish. The efficacy score is driven by a credible multi-filter UV system (UVB plus UVA coverage) and a supportive humectant base with glycerin, but the added glutathione/antioxidant story is not what makes this formula effective; niacinamide is present, yet not positioned as a headline treatment, and the hyaluronic-acid stack mainly improves feel and hydration rather than sunscreen performance.
