System Verdict
This sunscreen leans on standard chemical filters but the truncated formula and inclusion of oxybenzone make it more of a basic, slightly dated UV filter blend than a modern, high-elegance sunscreen. The efficacy score reflects adequate core UV protection from the combination of UVB and UVA filters, but without a complete INCI we cannot confirm SPF level, photostabilizing helpers, or film-forming polymers that distinguish top-tier sunscreens, while the presence of benzophenone-3 slightly drags both safety perception and modernity of the formula.
