Lips can become chapped or dry when they are exposed to the sun, wind and cold or dry air. A lip balm containing petroleum or beeswax will provide a barrier and help seal in moisture.
More moisture is lost through the lips than through any other part of the face or body.
When the lips lose moisture, the skin covering them can become tight and start to split.
It's very tempting to pick and bite off flakes of dried skin. This will only make the lips bleed and heal more slowly. Irritating the skin around the mouth may also trigger a cold sore, if you're prone to getting them.
It's also tempting to keep licking dry or cracked lips. However, this will only dry your lips more as the saliva evaporates.
The best thing to do for dry or sore lips is to regularly apply a lip balm containing petroleum or beeswax. You may need to try a few different products before you find one that works for you. Choose a balm with an additional sun protection factor (SPF) for protecting your lips in the sun.
A lip balm will act as a shield to protect your lips against the sun, wind, cold or dry air. It will trap in moisture and seal cracks against infection.
Avoid lip balms in little pots as repeatedly dipping your finger into the balm can introduce germs.
Sometimes, dry lips can become inflamed and feel sore. The medical term for inflamed lips is cheilitis.
Lips usually become inflamed as a result of infection. This happens when dirt, bacteria or fungi enter cracks in the skin of the lips.
If you have red, sore lips and think they are infected, see your doctor. They may prescribe an antibiotic or antifungal cream to treat the infection. This may also contain 1% hydrocortisone (steroid medication) to reduce the inflammation.
If the corners of the mouth are red and sore, you probably have a type of inflammation called angular cheilitis. This is often caused by bacteria or fungi and is treated with ointments applied to the area. Angular cheilitis can sometimes be a symptom of a type of eczema called [contact dermatitis](https://www.your.mdd41d8cd98f00b204e9800998ecf8427e
