With the advent of summer comes a host of skin related problems. The harsh heat and the dryness of these hot months can make your lips dry. Lips don’t contain oil glands like other parts of your skin and this is why they often dry out and become chapped. Because of this dryness you may frequently lick your lips. This strips moisture from the lips and the problem of dryness becomes worse. It is important to keep your lips hydrated during this weather to prevent this condition. According to some studies using chemical-laden lip balms can also cause chapped lips.
