System Verdict
Solid sunscreen base, but the added skincare claims are mostly window dressing. The efficacy score is driven by a complete broad-spectrum chemical filter system with avobenzone for UVA protection plus homosalate, octocrylene, and octisalate for UVB coverage, while glycerin, panthenol, and niacinamide provide real but secondary skin-support benefits. The botanical extracts, adenosine, and hydrolyzed soy flour sit too low to materially move performance, so this is strong as a sunscreen and only modest as a skincare treatment.
