Myth #9: Dry skin is just a harmless winter annoyance.

Itchy, flaky skin can be an irritating and unsightly consequence of cold, dry air. But should you just write it off as a winter annoyance? No, says Dr. Jaliman. Dry skin, if not kept at bay, can be a portal for infection. “It’s very important to keep dry skin hydrated,” she says. When skin becomes dry, it can lead to small cracks that can leave your body prone to infections. To prevent this, moisturize twice daily—after you shower and before bed—as well as throughout the day for body parts that are prone to dryness, like your hands. “I like Aquaphor,” says Dr. Jaliman. “It’s inexpensive and effective.”
