About this sunscreen

MAC Prep + Prime Face Protect is an SPF 50 chemical sunscreen lotion using an older-generation filter blend of Homosalate, Ethylhexyl Salicylate, Avobenzone, Oxybenzone, and Octocrylene. It wears with a balanced finish, low white cast, and a lightweight feel, and is generally friendly under makeup as a primer step. Protection is good. At 63.1/100 it is a reasonable makeup-prep option, though the dated filter set holds the score back.
