I use cortisone cream.

Ingy, I also saw The Docs yesterday and their input about cracking lips...
Felt when I saw this that it probably applied to persons that did not normally have AI disease.

I have found throughout the years that a 'dab' of tea tree oil on a Q-tip does the trick...  it has cured the slit corners of my mouth with a couple treatments... even in wintertime, when it easily could be blamed on the coldness.

Tea tree oil in bottle form can be purchased at Wal-mart for around $5.

Also, in past used the tea tree oil Q-tip 'dab' treatment on ulcers inside the mouth...

My thinking is that the inside and outside of mouth are experiencing same health issue.
Knowing we all are different; I think mine is fungal and tea tree oil states it treats fungal issues.

My note of caution; Careful where else you might be 'tempted' to use it!!!

Linda, that was very interesting about Cheilosis. A vitamin B12 deficiency can also lead to the sore mouth and tongue often associated with Sjogrens. It is periodically accompanied by a bitter or metallic taste. (Cigna, 2010) B12 deficiency impairs DNA synthesis, which affects all proliferating cells. Without B12, developing cells in the bone marrow cannot divide normally to form mature red blood cells. Instead, they become unusually large and misshapen and most never leave the bone marrow. A similar accumulation of large abnormal cells lining the digestive tract can cause a sore mouth and tongue.
