About this sunscreen
Ultraderm Mineral Daywear SPF 50 Sheer is a pure mineral sunscreen using Zinc Oxide alone. It has a dewy finish and runs a touch heavier on skin, with low white cast and low-sting comfort, and it is unlikely to clog pores. Protection is rated only moderate and it works poorly as a makeup base. With a score of 71.1/100 it is a middling mineral option, best worn on its own rather than under makeup.
