In all cases, the therapeutic goal is to maximize treatment efficacy and the patient's quality of life, while minimizing side effects. Achieving and maintaining control of psoriatic lesions is the central goal in treatment. Physicians and patients need to understand that there is no definitive cure for psoriasis ( Figure 4 ) . Control of the disease may mean that lesions are not as thick or as red as they were before treatment, but some degree of erythema may remain. Most often, treatment does not result in complete clearing of the lesions.
