Reasons why our lips chap.

Tweet

There is no mistaking the signs of chapping: painful slits and cracks that are very slow to heal. Not only the lips but also the whole face, the hands, and sometimes the heels and other body parts may be affected. The basic cause of chapping is the drying out of the uppermost layer of the skin. Precipitating factors includes soaps and detergents, dry indoor air, and exposure to cold, windy weather. Prevention and cure call for the same measures. You should gently pat-not vigorously rub-your skin to dry it after washing, and use emollient creams or lotions liberally and regularly to soften and moisturize the skin. Petroleum jelly is the most economical and effective that I use for these dryness.
