Frostnip, a mild form of frostbite, tends to affect the earlobes, cheeks, nose, fingers, and toes. Signs of frostnip include pale skin, numbness, or tingling in the affected area. Avoid frostnip by dressing warmly, including a hat, earmuffs, and gloves. The best treatment is to re-warm the affected areas. Although frostnip is uncomfortable, it doesn’t cause any damage to skin.
