###Human: I have dry scaly red patches around mouth. Can this be perioral dermatitis? ###Assistant: Hi. I have gone through your case. Right now you have applied too much moisturizer (attachment removed to protect patient identity). Please apply Hydrocortisone cream two times a day for 10 days. If blisters or erosions are present then you may need oral steroid as well. Sometimes, a sulfa group of drugs shows photosensitivity and cross-reactivity to another agent as well. Apply sunblock regularly. Maintain good oral hygiene.
