About this sunscreen
Earth Rhythm Phyto Shield SPF 50 is a pure mineral sunscreen using zinc oxide and titanium dioxide. It has a balanced finish and stays lightweight, though it carries a medium, somewhat visible white cast common to mineral formulas. It does not sting and has low pore-clogging potential, so it is generally friendly for sensitive or breakout-prone skin, and it works well under makeup. With good protection and a score of 79/100, it is a solid mineral daily option.
