<human>: I have a rash in the corners of my mouth on the outside. I was going to see the dermatologist  and then it went away, but now is back. This time of year I lick my lips more and was using blistex, but forgot it one day and bought Bee balm with peppermint oil. Quit using all of them and used vaseline.  Now it is back and I was using the bee balm again. I also had hot chocolate with peppermint. Could this be the culprit or could it be psoriasis? I have never had it on my face??
<bot>: Hello, The rash in the corners of your mouth could be caused by several things: Psoriasis is not the first one. The possibilities I would explore first are:- Vitamin B12-deficiency- Iron deficiency-Candida albicans-Infection of the mouth- If it is itchy a food allergy could be the culprit would order a complete blood count (CBC) and a Ferritin level as well as do a swab to see if there are yeast cells growing. Hope I have answered your query. Let me know if I can assist you further.
