Silky Skin
Chill factor: Low humidity outside and dry heat inside sap moisture from the skin, leaving it flaky, rough, and red.

A Shorter Shower

Hot water is drying. So is soap. When you're covered up all day, water is enough to get your arms and legs clean. Keep your showers lukewarm and lather up only the areas where you sweat.

Double-Duty Protection
Eric Bernstein, MD., Dermatologist
Hometown: Ardmore, Pennsylvania (Average winter temp: 36°F)

A sunscreen with zinc or titanium dioxide protects you from the wind as well as the sun because it creates a physical barrier on top of your skin. Apply it liberally even if you're going to be outside for only a few minutes, because you're exposed to plenty of UVA light through the windows in your home, office, and car.

A Refreshing Cure For Redness

Steep chamomile in hot water, then make ice cubes from the infusion. Before you moisturize, gently run one of the cubes over your face. The chamomile, a natural anti-inflammatory, can help reduce redness; the ice also calms inflammation.
