How to Prevent: Prolonged exposure to harsh winds can leave skin raw and chapped. Before heading out, layer on a rich salve, such as L’Occitane Mini Pure Shea Butter ($6, www.loccitane.com), to create a thin barrier between your skin and the wind. Then coat skin with an SPF 30 sunblock. For added insurance, wear a hat or a scarf that covers your neck and nose.

How to Treat: Smooth and hydrate wind-ravaged skin with a nourishing cleanser, such as Albolene Moisturizing Cleanser ($11, www.walgreens.com). Wash with warm — not hot — water and follow with a moisturizer. Sooth sore, irritated patches with a 1 percent hydrocortisone cream. RS pick: Aveeno Maximum Strength 1% Hydrocortisone Anti-Itch Cream ($5, www.drugstore.com).

When to See a Professional: If itching and soreness persist for more than three or four days, ask a dermatologist for a stronger, prescription cream, which should accelerate the healing process.
