Acne – Diagnosis and treatment – Mayo Clinic

The treatment regimen your doctor recommends depends on your age, the type and severity of your acne, and what you are willing to commit to. For example, you may need to wash and apply medications to the affected skin twice a day for several weeks. Topical medications and drugs you take by mouth (oral medication) are often used in combination.
