Using your smartphone outside

Checking email, posting photos and responding to texts on the go may not be doing your skin any favors. An observational study found that UV light reflects off small screens—including smartphones, iPads, Kindles and laptops—and could go right onto your face. "If you're on your device when sitting outside, this can amplify the sun's effect," says dermatologist Joshua Zeichner, MD, who adds that this repeat exposure can contribute to everything from sun spots to wrinkles. To keep your skin (and mind) happy, consider taking a break until you're indoors.
