About this sunscreen
Maria Ross Paris SPF 40 is a chemical sunscreen using an older-generation filter trio of octinoxate, Ethylhexyl Salicylate and avobenzone. It wears light with a balanced finish and low white cast, and breakout risk is low, though it can sting somewhat near the eyes. Despite the SPF 40 label, the protection here rates weak. The score of 49.0/100 suggests its real-world coverage is limited, so it is best used with care for extended sun exposure.
