About this sunscreen
Thinkbaby SPF 30 Clear Zinc Sunscreen is a pure mineral formula relying solely on Zinc Oxide, a common choice for sensitive and baby-skin routines. It is non-stinging with a low pore-clogging profile, but carries a medium white cast and feels somewhat heavy, and it is a poor base under makeup. The finish is balanced rather than matte or dewy. With moderate protection and a score of 69.4/100, it is a gentle mineral pick where a single zinc filter and easy tolerance matter more than a featherweight feel.
