I had a tattoo removed a couple of years ago - it took almost 2 years of treatments! It was on my shoulder, a purple flower with lots of green stems, outlined in black. Apparently, green and purple are the worst colors to remove. After about the first year or so, the dermatologist who was doing it wouldn't even take any more money from me! it became his little project. He thought upfront that it would be gone in 5-6 treaments. In all fairness, about the last 4-6 times I went we were only working on one little stem that curled up almost in a tail that was being really stubborn. Now you'd never know I had one unless I pointed it out....then if you really look you can see a faint green color on certain areas.
