Can Anything Reverse Hypopigmentation?

I had a laser treatment on two small scars to help blend the white hypopigmentation around the incsision site. I think it was fraxel....Once the treatment was done there were two overlapping little squares made up of tiny brown dots. It has been 2 months and I can still see the square and dots outline except it is not brown anymore, its is white. SO instead of blending the hypo it created more hypo skin . Is this normal? Will it fade? did he over laser or under laser? can a dermatalogist help?
