I've undergone several Fraxel Dual treatments to treat minocycline hyperpigmentation but have seen little improvement. It's very depressing. I've read a few articles describing resolution of minocycline pigmentation using q-switched ruby or alexandrite lasers, but in all cases the patients have blue-grey pigmentation- I would describe mine to be mottled, spotty and brown, not blue-grey. Will wither laser be as effective in my case? I'd like opinions before spending more time and $. Many thanks.
