System Verdict
This is a solid sunscreen formula, not a miracle moisturizer. The efficacy score is driven primarily by a complete broad-spectrum UV filter system with avobenzone, homosalate, octisalate, and octocrylene, plus a decent supporting base with humectants and film formers that help wear and finish. Niacinamide, panthenol, and sodium hyaluronate add some real secondary hydration and barrier support, but they sit well below the filters and do not meaningfully transform this into a treatment product; the formula's main job is still UV protection, and it does that competently.
