Treatment Types

Medication: The most common form of treatment for acne conglobata is isotretinoin (Accutane) which is often used along with prednisone. Acne conglobata can be resistant to treatment, over time it can be controlled through aggressive treatment. More severe cases can be treated with dapsone, a form of medication which is used in the treatment of leprosy.

The CO(2) laser is used to open the cysts and remove the top of the sinuses and their tracts. Topical tretinoin therapy is then initiated simultaneously in order to prevent the appearance of new acne lesions. This two pronged approach is a powerful treatment option for acne conglobata.
