Help please? what is the most effective treatment for perioral dermatitis?

Perioral dermatitis: Cant provide you with treatment without knowing why you have this condition. You have given us no information about yourself. It often happens after the use of topical steroid on the face.potential causes including chewing gum, certain medications, hormone changes, and autoimmune diseases. Lip licking, lip chewing, sucking, and allergies to ingredients in certain dental products. See dermatologist

Perioral Dermatitis: The most important advise I have for my patients is DO NOT LICK YOUR LIPS AND ADJACENT SKIN with your tongue. See a Dermatologist if that was not the cause.
