System Verdict
Excellent sunscreen, but not a meaningful treatment product. The efficacy score is high because the formula uses a strong modern chemical filter system with broad UVA/UVB coverage, plus a lightweight base that should wear comfortably; niacinamide, sodium hyaluronate, and allantoin add supportive benefits, but they sit in a sunscreen context and do not drive the score the way the UV filters do.
