Best basic face sunscreen
“It’s not just UV rays but also infrared light and heat that cause cellular damage and pigmentation. SkinMedica Total Defense & Repair SPF 50+ is the only sunscreen to offer this trifecta of protection. My daily regime includes a tinted sunscreen with SPF 30, 40, or 50. It’s important to keep in mind that makeup with SPF 20 sunscreen math favors only the highest SPF, not the sum of them all: SPF 40 + SPF 20 = SPF 40, not SPF 60. —Ellen Marmur, MD, dermatologist at Marmur Medical, Associate Clinical Professor of Dermatology at The Mount Sinai Medical Center
