Laser is the on;y nonscarring removal method. Using cream anesthesia or injections, it's not very painful. Black is easiest; colors take more treatments. You should expect to need several monthly treatments, and some pigment may remain. To find a reputable place, call the dermatologists in your area. Price is important, since the treatment is pretty standard. Questions to ask: Do you treat many tattoos? Do you have lasers for all the colors of my tattoo? Cost should be in the range of $150 per treatment.
