is the picosure laser safe on darker skin im skin type 5. i have an ALL BLACK INK tattoo that is two months old i had this tattoo placed over a scar to try and somewhat hide the scar but didnt come out like i planned. I want to know would my tattoo be able to get removed since its over old scar tissue? and would the picosure laser give me faster results thank the q-switched lasers. Which one would be better for my skin tone and better result wise?
