Cystic acne is frustrating because the breakouts are painful, unsightly, long lasting and often leave marks or scarring. Luckily, we have many treatments available for cystic acne. These treatments include oral medications (Antibiotics, Hormonal Therapy and Isotretinoin, also knows as Accutane), Photodynamic Therapy, and steroid injections. Topical agents and oral medications are used daily to prevent and treat breakouts.
