Instead, she says, you should be using sun protection products with moisturizers in them. In other words, the shelf space that's traditionally been reserved for an a.m. moisturizer that's got SPF in it should be swapped, instead, for a sunscreen with moisturizing ingredients. Still with me? Since products that are marketed as sunscreen are subject to FDA regulations (which, as Dr. Gohara pointed out, moisturizers are not), you'll be sure you're getting the purported amount of SPF protection. If physical sunscreensdon't tell you anything, go ahead and read about the basics here.
