Many of us find it surprisingly difficult to heal splitting lips, particularly when similar sized cuts or splits on other parts of the body seem to heal much more quickly. These persistent splits are extremely painful as everyday activities such as eating, drinking and speaking all cause movement and reopening of the sores.
There is more to it than that though. Although many associate this condition with the cold or flu virus, it is completely separate. Even though you are more likely to have split lips in winter, as extremes of temperature can cause aggravation, it is caused by a bacteria or fungal infection which takes hold on the damp, warm skin at the corners of the lips. The condition is known as angular cheilitis.
A doctor would normally provide a steroid cream to both soothe and heal the area and although this might work temporarily, it does not address the root cause and recurrent outbreaks, each more ferocious than the last, often occur. To heal splitting lips naturally, it is important to isolate the cause of the moisture which must be reaching the affected area.
Common causes of moisture at the edges of the mouth include ill-fitting dentures and dribbling due to pen biting and finger sucking. Taking steps to have dentures corrected and discouraging pen biting etc are good starting points. Bacteria and fungal infection cannot thrive without moisture and air so once you discover how to prevent this happening, you will learn how to heal splitting lips naturally.
If the condition is mild, using a watertight barrier such as petroleum jelly or unperfumed lip salve can help considerably. Both of these will soothe and protect the area and prevent moisture from further damaging the area.
If you have had the soreness and pain for more than a day or two, it is highly likely that you have angular cheilitis which may worsen without treatment. Once you begin using a proper cure, you could have complete pain relief and healing within 24 hours.
