About this sunscreen

Alex MD PHD SPF 50+ Daily Defense is a fully mineral tinted sunscreen using only Titanium Dioxide and Zinc Oxide, which makes it a common pick for sensitive skin. It wears matte with low white cast thanks to the tint, though the mineral base feels a touch heavier than a lightweight fluid. Breakout risk is generally low and it does not commonly sting. Scoring 80.8 with good protection, it is a dependable daily mineral option for those who prefer zinc and titanium filters.
