Chapped lips are the result of our lips being too dry. Chronic chapped lips can result from nutritional deficiencies and dehydration, or over exposure to sun or cold and windy conditions. The explanation for severe and chronic dry lips is that our skin has lost its moisture retention capacity. As a consequence, our lips become easily chapped. The chapping further reduces the moisture retention capacity and this vicious circle results in the problem becoming chronic and increasingly severe Avoid licking your lips.

Saliva evaporates rapidly and digests the slim membrane protecting lips, leaving lips drier than before you licked them. Because sunlight vulnerability can dry and blow the rind, take a lip ointment or salve containing sunscreen to defend the lips from detrimental rays. Medical care should be sought if symptoms continue without advance. Your doctor may select to dictate antibiotics or may regard prescription handling for dermatitis.

Primary Causes of Chapped Lips
Exposure to the seasonal elements - Dry air, wind, sun and/or cold temperatures can wreck havoc on sensitive, unprotected lip tissue.
Contact dermatitis should be considered and may be stemming from allergies and/or topical irritation.
Medications could be a factor. Suspect any newly started medications as the potential source of irritation.

Treatment of Chapped Lip
Some common treatment of Chapped Lip :
Apply lip balm or petroleum jelly. You can also try coating your lips with skin moisturizer, vitamin E oil or aloe vera gel. These greasy products help keep your lips properly moisturized.
Drink plenty of water to prevent dehydration.
Keep in mind that cracks at the corners of your mouth can indicate riboflavin deficiencies; you can treat this with vitamin B-2 supplements.
Use a humidifier to moisturize the air in your home, helping to prevent both dry lips and skin.

Use an oil-based lubricating cream, such as Aquaphor Healing Ointment, or lip balm containing petrolatum or beeswax.

Choose a lip cream or balm that contains sunscreen. Sun exposure contributes to chapped lips.

Treat chaffed, chapped and scaling lips overnight with a homemade ointment mixed from 1 tsp glycerine, 1 tsp lemon juice and 1 tsp castor oil. Spread on lips overnight, refrigerating the leftovers for future use.

Add humidifier(s) to your home. Lips, hair, nails and skin all thrive in humidified air.
Add a coat, when you wear a coat - Keep lips shielded against the elements with a coat of petroleum jelly, balm (non flavored, without phenol or camphor) or Aquaphor ointment (a celebrity favorite).

Seal in the moisture. Right after the compress, apply a thick coat of an emollient ointment like Vaseline or a lip balm containing waxes or lanolin to hold the moisture in.
Step up to cortisone. If a week of compresses and emollients don't do the trick, you can add over-the-counter 1 percent hydrocortisone ointment to your regimen. Use the hydrocortisone under your emollient ointment, he suggests. Try this for two weeks.
