About this sunscreen

Dot and Key Sunscreen Stick is a chemical sunscreen in stick form, built on older-generation filters including ethylhexyl methoxycinnamate, avobenzone, and benzophenone-3 with a little titanium dioxide. It wears with a balanced finish, low white cast, and a lightweight feel, is rated low for pore-clogging, and works well under makeup, though it can sting for some users. The labeled SPF is not specified here. With moderate protection and a score of 59.1/100, it is a convenient stick for touch-ups rather than a top pick.
