Is it normal that a month after the end of the treatment with Izotek, a pimple popped up?

You have been using Izotek for quite a long time - on average, the treatment lasts from 16 to 24 weeks. According to the documentation of the drug - in most patients it is necessary to use only one course of treatment, but the symptoms of acne may disappear for up to 8 weeks after the end of the course. In my opinion, the skin should be observed for some time (e.g. until 8 weeks have elapsed since the end of treatment). If her condition deteriorates significantly, you may belong to the group of patients who require repeated therapy. On this subject, the most comprehensive answer will be given by the dermatologist who deals with your case.
