A sudden change from a beach environment to a snowy day high upon a mountaintop can be a big shock to your skin. Sun, wind, and cold can cause sunburn, windburn, and frostbite. Steamboat dermatologist Sandra Eivins says, "Wind in addition to sun accelerates the damage that the sun does. You really want to try to keep the wind off of your skin."
The best solution is to cover up completely with a helmet, goggles, and neck gaiter or ski mask, so your face doesn't get wind burned, or wind chapped. Dr. Eivins also says a waterproof sunblock helps: "It's going to have more protective qualities than an oil-free product."
You also need to be especially careful on the bitterly cold days, as frostbite can occur. Frostbite can be anywhere on the body, but skiers and riders typically get it on the tip of the nose, ear lobes and rim, fingertips, and toes. The area will become numb, or tingle and feel like it is burning. The skin will then change color, becoming white when exposed to extreme cold. Get out of the cold immediately if this happens. Do not rub the skin.
For extremely dry, cracked skin, consider using a product recommended by many dermatologists called Aquaphor Healing Ointment. Many skiers and snowboarders have found it to be valuable as it effectively helps heal even the roughest skin and lips. It's fragrance-free as well and is widely available.
Remember, mittens are better than gloves as the collective heat of your fingers keeps your hand warm. Keep a close eye on kids when they are outside, too, to make sure they don't remove coats, hats, or gloves.
