I am suffering from Vitiligo for the past 5 years. In the past two years the patches have become active and are spreading on my face and hands. Started off with Allopathy medication but that did not bring any result. Soon switched to Ayurvedic treatment which includes medicines and sun exposure and for 3 months I also took steroids and I am recovering slowly. But my problem is that the patches which recovered are again becoming white. So why is this happening? What should I do?
