System Verdict

This is a very solid modern chemical sunscreen with strong UV filters and pleasant hydration, but the minty botanicals and t‑butyl alcohol stop it from being a truly skin‑calming daily staple. Efficacy is driven by a robust, photostable filter combo (UVA: Diethylamino Hydroxybenzoyl Hexyl Benzoate plus Methylene Bis‑benzotriazolyl Tetramethylbutylphenol; UVB/broad: Ethylhexyl Salicylate, Homosalate, Polysilicone‑15, Bis‑ethylhexyloxyphenol Methoxyphenyl Triazine) in high positions, giving reliable SPF50+/PA++++ coverage when applied at full 2 mg/cm². Hydration and barrier support from glycerin, propanediol, hyaluronic acid and mid‑list niacinamide are appropriate for a sunscreen base but not at treatment‑serum levels. Green tea (matcha) extract and ice plant extract provide some antioxidant/soothing support, though these are secondary to the filter system. Safety is generally good for non‑sensitive skin, but the inclusion of three Mentha extracts and t‑butyl alcohol creates avoidable irritation risk for reactive or rosacea‑prone users.
