Hi,my husband have been treated for vitiligo almost 2 years with the PUVA but was really a bad time. We went to Cuba as missioneries and know he is 1 year and 4 months with Melagenina Plus and you can see the results. He does not have to be exposure to any light or sun and he does not have to take no pills that can make him sick or anything. All is so easy and no damage at all and the progress is impressive. If you want more information let me know. God bless you and we hope that you can find it also.
