About this sunscreen
3LAB WW Day SPF 40 is a chemical day cream using older-generation filters including Homosalate, Ethylhexyl Salicylate, Avobenzone and Octocrylene. It has a matte, lightweight finish with low white cast, does not commonly sting, and rates excellent as a makeup base, so it sits well under foundation. Pore-clogging is rated low. Protection, however, is rated weak and the overall score is 49.0/100, so it is better thought of as a cosmetic day cream than a primary sunscreen.
