Angular chelitis is a description of the lesion and not the cause. It is often mixed fungal and bacterial. It may be related to a nutritional deficiency or allergy but you still need to heal it. If OTC anti-fungal doesn’t work then you need a prescription antibiotic.

Including your own. My derm thought it was that and failed to order a blood test. I suffered through if for a year thanks to his failure to diagnose.

Bottom line - it could be a number of things. I’d see your internist.

Have had this. Take b complex zinc and l-lysine and do the mix suggested above for topical. This is what cured mine. And, after having this a few times in my teens and twenties I do not have it anymore - for at least 20 years.

That’s what heals it for me.

Oddly, I also haven’t had it in years since I quit soda and candy.

I sometimes get it and it only heals with Carmex.

Since there are a range of potentially ominous causes of angular cheilitis, best to see a derm.

I have this condition that flares up from time to time and it's definitely fungal. I use a prescription antifungal cream (Nystatin) on the cracking then layer it with Aquaphor. Must do this several times a day for multiple days.

With all this suggestion I wonder what OP is going to do.

I got this as a resident, and the attending on my ambulatory care rotation said it’s fungal. He said to mix together a bit of an antifungal cream (like for athletes foot) with some cortisone cream or ointment. About 50:50 mix. Put it on before bed and a few times a day. Try not to lick it. Take a multivitamin.

Take vitamin B or get checked for low vitamin B.

My dd had this from eating a lot of apples. Derm said to take B vitamins and it was a miracle!

Yes this worked for me. Definitely a B type vitamin (niacin?) deficiency for me. Healed when I took supplemtal B+ (B12, B3, etc mix)

Stop the antibiotic ointment, try some OTC anti fungal topical.

Eucerin cream original (in the pot not pump type container) is honestly magic- you can use it on your lips for moisture without the stickiness of Vaseline.
