I have been using monobenzone for a year now I have vitiligo it has made my skin even again I am very pleased with the results but recently I have been developing large darker patches over my back I have never used the cream on my back so I'm not sure why this is has anyone else experienced this? If I use the cream where the darker patches have formed will it work?

Monbenzone produces disfigured skin, dark and light patches both. The longer you use or abuse it, the more you your skin will mimick vitligo but with more and more dark patches, instead of less.
