About this sunscreen
COSRX Shield Fit All Green Comfort Sun is an SPF50+ PA++++ mineral formula using zinc oxide and titanium dioxide for a matte result. It feels lightweight and stays matte, but it carries a high chance of visible white cast, which is typical of fully mineral formulas. It does not tend to sting, has low breakout risk, and works okay under makeup. With a score of 79.1 and good protection, it is a strong matte mineral option if you can manage the cast.
