Would a laser used for removing tattoos also work for pigmentation caused by medication?

I have had what look like bruises running the length of both my shins. I was told it is "hydroxychloroquine induced pigmentation", from RA medication. I stopped it over a year ago but I was told they are permanent. I found one article a while ago discussing a trial using the Q switched laser to attempt to remove this pigmentation, but no other info since that. Any information on using either the Q switched laser or maybe the newer Picosure/Picoway lasers for this? Thank you!
