About this sunscreen

Cay Skin Universal Mineral Face Lotion SPF 55 is a pure mineral face lotion using zinc oxide as its only UV filter. It has a balanced, lightweight finish with low white cast and is rated okay as a makeup base. The formula is low for pore-clogging and low for sting, so it is gentle in feel. Despite the high SPF label, protection is rated weak and the overall score is low in our system, so it sits near the bottom of this group.
