As you may have noticed it, acne has "good weeks" when it gets better on its own, and "Bad weeks" when it gets worse on its own, irrespective of treatment.
The same can happen during Isolaz treatment.
At Lakeviewderm (3 Offices in Chicagoland) we are treating numerous patients with Isolaz and they all get better after 2 to 3 treatments in moderate cases and 4 to 5 treatments in severe cases. We also encourage our patients to use topical treatments in between. We spend time explaining how to use small amounts of topicals to the entire face, avoiding irritation and using only oil-free moisturizers, makeups, etc.
Make sure that you are being treated by an experienced Board Certified Dermatologist.
