Efficacy evaluation
Efficacy evaluations at week 6, 12, 33 and 52 were performed using the
IGA scale (Table II and III). IGA assessment throughout the trial was
performed as open-end analysis by the treating physician. Furthermore,
patients rated their satisfaction according to improvement in overall
appearance and texture on a 5-point Likert scale (very dissatisfied,
dissatisfied, no opinion, satisfied and very satisfied) at the end of
the study.
