A member asked:

I find a red rash under my mouth, i m not sure is it dt.applying a cream or not but how to differentiate if it's allergic rash or perioral dermatitis?

A doctor has provided 1 answer

See details: Perioral dermatitis is a rash around the mouth and not a specific diagnosis. Allergy would be unlikely. See a dermatologist if it persists.
