Dermamelan Cream with Roaccutane

I have develped hyper-pigmentaiton in my body after wrong fractional laser procedure done on my back. Doctor prescribed Dermamelan cream claimeding that it treats the pigmentations. at the same time I am usuing Roaccutane for one month immiediately after the laser treatment. Is there any problem in using this Dermamelan cream with the tablet? the cream is causing mild peeling effect and some dryness and redness in my skin. Thanks
