About this sunscreen

Skin Authority Daily Defense Moisturizer SPF 30 is a chemical SPF moisturizer using older-generation filters including Butyl Methoxydibenzoylmethane, Homosalate, Ethylhexyl Methoxycinnamate, Octocrylene and Benzophenone-3. It wears with a balanced, lightweight finish and low white cast, though the filter mix tends to sting if it reaches the eyes. Protection is moderate at SPF 30, and the 55/100 score reflects the dated filter set despite its workable everyday feel.

Will the Skin Authority Daily Defense Moisturizer SPF 30 sting my eyes?
