System Verdict
Elegant UV protection with annoying alcohol + fragrance baggage. Multiple modern filters (UVB filters plus Bis-Ethylhexyloxyphenol Methoxyphenyl Triazine and some titanium dioxide) provide solid broad-spectrum protection and a cosmetically pleasing texture, but the reliance on denatured alcohol high in the list and a fully loaded fragrance allergen blend drags down both tolerability and the overall efficacy score for sensitive or barrier-compromised skin.
