About this sunscreen
Tarte Guard 30 Mineral Powder Sunscreen Broad Spectrum SPF 30 is a pure mineral powder built on Zinc Oxide. It finishes matte, stays lightweight, and shows little white cast, with low pore-clogging risk and an okay fit over makeup, which suits powder reapplication through the day. Powder formats are generally hard to apply at full strength, and the protection axis here is weak. With a score of 49.0/100, it is best as a top-up rather than a primary sunscreen.
