Analysis updated June 2026 · How Scout scores
At a glance
Summary
This sunscreen contains mineral-based active ingredients, titanium dioxide and zinc oxide, which are generally considered safe and effective for sun protection. However, the presence of synthetic compounds like cyclopentasiloxane and dimethicone, which are used for texture and spreadability, indicates a moderate level of processing. While these ingredients are not highly concerning, they do not contribute to a completely natural formulation, which affects the overall score.
