Acne

Diagnosis

Your doctor usually can diagnosis acne based on a simple physical examination. He or she will look for acne comedones, pustules, nodules and cysts on your face, chest, back, upper arms and shoulders. He or she also will ask questions about your medical history to try to identify contributing factors. You will be asked about your menstrual history, patterns of hair growth, cosmetics, facial cleansers and medications.

Expected Duration

Acne flare-ups may occur at any time after puberty, but are more common during the teen years.
