Im having these two white spots from last 1-2 year I think and recently I went to doctor to show this because I was scared because I thought that this is that disease in which many parts of body turn into white coloue. So the doctor told me to apply melanocyl solution on the place where I'm having this white spot, on Sunday's and expose it to sunlight for 1/2 min (30 sec) . But can u tell me if that can I wash my hand after applying or is this the right solution which will cure it. Thanks.
