Do your research. Choose a place that is reputable, and ask them about the lasers they use. Right now, the best laser available is the Picosure. It's not necessarily mandatory that an office use this laser, but you want to make sure that they use something modern, as the technology is constantly advancing. The average cost for each tattoo removal session is $40 to $100 per square inch, and most tattoos are removed within four to six sessions. Though this certainly adds up, it's unwise to choose a place below that price point.
It is important to be more committed to your tattoo removal than you were to your tattoo. The process can take a while and costs a lot, so it can be tempting to give up and try to redo your tattoo. Be sure that it's the right decision for you and that it's truly what you want.
