Patients often come in wanting a tattoo removed for a specific event. They have a wedding in a few months or an important job interview coming up. Unfortunately, the process doesn't work that way. Depending on the size, location, and ink used for the tattoo it can take weeks — even months — before it's fully gone. This is something that you need to come to grips with right away if you're considering laser tattoo removal. Still, you don't want to go into the process without a rough idea of how long it'll take.
