If the corners of your mouth are cracked, it is probably a result of lack of moisture. If you live in the desert in the winter, where the humidity is very low, dry skin can be a real problem. There are several things you can do to correct this problem. For immediate relief, try rubbing petroleum jelly on the corners of your mouth. This will soften the dry areas, making your mouth more
. comfortable. Use the petroleum jelly three or four times a day until the cracking is gone. You will also need to increase the moisture in your body. You can achieve this by drinking more water. In a dry climate, you will need a minimum of eight (8 oz) glasses of water each day. You might also need to increase the amount of moisture in your home. You can do this with a humidifier. You can purchase a humidifier at a reasonable cost at most super stores, such as WalMart or Target. If you don't want to buy a humidifier, you can simply keep a pot of gently boiling water on the stove. This will produce steam and that puts moisture into your home.
