The article includes Dr. Patel's expert commentary on why using spf moisturizers can be useful, especially if work indoors.

Maybe it’s the time-saving thrill of combining two steps into one; maybe it’s feeling good that you actually remembered to apply sunscreen. Whatever the motivator, moisturizers spiked with SPF have been a staple in many of our routines for quite a while. But with summer peeking through, we asked top dermatologists a question that’s been weighing on us: is the SPF in our moisturizer enough?

“When applying moisturizer with sunscreen instead of just sunscreen, most people will apply too thin a layer for it to be effective enough to protect against the sun’s harmful rays,” says Fort Lauderdale, FL dermatologist Dr. Matthew J. Elias. “There are actually studies in Europe supporting the fact that users don't apply nearly enough sunscreen to their skin—to their face, in particular—when they use moisturizer with sunscreen as opposed to sunscreen alone.”
