On each visit will be examined by clinical parameters validated scales of assessment internationally (PASI), which provide the exact data of changes in the framework of each patient in each parameter measured. As parameters of the tolerability will be evaluated frequency and intensity of adverse events and the potential of irritative formulations, will be held photo of patients and questionnaires of cosmeticidade the formulation. Patients will be geared not to expose to the sun during the treatment period.
