If you have chapped cracked lips that do not heal, then it is likely that you have the common but very painful condition known as Angular Cheilitis. Although not life threatening, this is a very persistent and aggressive skin condition which many people find very difficult to shake off.
Caused by a bacterial infection, if left untreated, it can easily develop into a full blown yeast infection and many then find that each attack becomes more severe and lasts for longer until it is an almost permanent feature. Of course, not only do sufferers have the pain to deal with, but Angular Cheilitis is in a very prominent position on the face which can cause embarrassment.
However, the condition can be brought under control. The edges of the mouth are the perfect breeding ground for bacteria as they can be both damp and warm. This is very much an issue if there is a tendency to drool or dribble. This can happen due to badly fitting dentures or mouth braces, pen biting or thumb sucking. If any of these apply, then take steps to have dentures/braces corrected and try to discourage pen biting/thumb sucking, possibly by painting a bitter anti-nail biting liquid on the offending object!
Chapped cracked lips that do not heal can be managed by drying up the affected area. This will starve the bacteria or fungus of oxygen, without which it simply cannot survive. For most people this means surprisingly fast relief-often within a few hours.
If you have had cracked lip corners or scabs for more than a couple of days, it is likely that the condition has taken hold.
