About this sunscreen
Thalgo Age Defense Sun Lotion Body SPF 15 is a chemical sunscreen built on a hybrid filter blend of avobenzone, Tinosorb S, octinoxate and octocrylene for broad-spectrum cover at a modest SPF 15. It has a matte finish with low white cast and a lightweight feel, and it sits well under makeup. Pore-clogging risk is generally low, though it may sting a little if it gets into the eyes. With a score of 69.7/100 and good protection, it is a reasonable everyday body option, best where SPF 15 is enough rather than for long sun exposure.
