I've just completed session 6 of laser tattoo removal. The ankle tattoo was about 1 1/2 inches in diameter. So far, about 70-80% of the black, red, and blueish/green ink has faded. There is one part, however, that has not faded at all. It is black, and the ink must be pretty deep since it is not responding. The area is a smallish dot, but it is so dark that it draws attention to the tattoo. My doctor has used both the Yag and Ruby lasers on it. Any suggestions for other things we could try?
