Diagnosis of Perioral dermatitis
Diagnosis will be made to confirm your condition. With just a visual examination of your skin and details on your medical history, your doctor will determine whether it is a Perioral dermatitis. Your doctor or dermatologist will perform a skin culture test to rule out a possible infection. They’ll swab a small patch of skin in the affected area for this test. The sample extracted will then be sent to the laboratory to know if any skin cells have bacteria or fungi infection. If the rash doesn’t respond to standard treatment, your doctor or dermatologist may need to conduct a skin biopsy.
