Firstly, Hypnotherapy and Psychotherapy are both excellent aids to help control emotional stress associated with vitiligo and other skin diseases(1). In one study conducted in Russia, not only were psychological problems eliminated but the researchers also observed marked repigmentation in over 20% of cases and that the period necessary to achieve marked repigmentation (i.e. of more than 50%) was twice as fast with psychotherapy. 

This indicates that psychotherapy and hypnotherapy not only may be effective therapy by themselves but they are almost certainly a beneficial adjunct to other therapies in helping to speed up the recovery process were cut down by half.
