About this sunscreen
ACO Kids Sun Stick SPF 50 is a hybrid sunscreen stick with a robust filter set, including Diethylamino Hydroxybenzoyl Hexyl Benzoate, Bis-Ethylhexyloxyphenol Methoxyphenyl Triazine, Ethylhexyl Triazone and Titanium Dioxide. The stick format has a dewy finish and a heavier, more substantial feel, with a low white cast.
