System Verdict
This is a solid sunscreen with a genuinely thoughtful base, but the formula’s real strength is UV protection and barrier support—not the flashy antioxidant marketing. The efficacy score is driven by a complete broad-spectrum filter set (avobenzone, homosalate, octisalate, octocrylene) plus a well-built support matrix of glycerin, sodium hyaluronate, ceramide NP, cholesterol, phospholipids, and soothing agents; astaxanthin is present but does not meaningfully drive performance. The score is capped because the UV filters are older organic filters rather than the most advanced modern system, and the “extra” antioxidants are supportive rather than decisive for skin results.
