Q. A friend and I were both recently diagnosed with perleche or angular cheilitis. Although the prescribed medicine (ciclopirox and fluticasone creams) clears it up, the irritation comes right back.
I have very dry lips, and use lanolin to moisturize them. Could this exacerbate the condition? Are there any effective home remedies or nutritional improvements I could try?
A. In Angular cheilitis (perleche) sore red cracks appear at the corners of the mouth. This painful condition goes hand in hand with dry, chapped lips because the cracks offer a foothold for fungus. That’s why the antifungal medicine ciclopirox helps clear it up, together with the strong steroid fluticasone that fights inflammation.
Licking dry lips contributes to the problem. This is a catch-22 because when lips are dry there is a great temptation to lick them. That tends to make things worse.
Although lanolin can be an effective moisturizer, some people react badly to it. You might try switching to a different chapped lip treatment.
Other lip balm ingredients to watch out for include sunscreens and peppermint. Both can trigger sensitivity reactions. Some people end up in a vicious cycle with their lip products. They get temporary relief, but compounds in the moisturizer actually can be irritating. Some people have dubbed this sort of problem a lip balm “addiction.” That’s because it is so hard to stop using certain products.
Iron or zinc deficiency or an inadequacy of B vitamins might contribute to the cracks in the corners of your mouth. Your doctor could test to see if you are low on any of these nutrients.
