I had a large, brand new, pro black and grey tattoo lasered off a few years ago. It took 9 sessions, a lot of money and a load of pain to achieve its current, barely visible condition. After the first two treatments I started using Emla cream before each session & Bio Oil massaged in several times daily (on advice of laser clinic) afterwards. I also drank plenty of water, took zinc supplements and arnica & used a vibrator on the whole tattoo once the skin damage from the laser had healed. No one advised me to do this but I figured that since the laser works by breaking down the ink so the body can eliminate it, the vibrations might prevent the skin from re-encapsulating the ink and allow the system to expel it more efficiently. Can't say for sure, but I think it helped. A friend with a very old, amateur, black tattoo started getting hers lasered at the same and did everything I did except the vibrating. According to everything I've read, being years older and amateur, her tattoo should have faded faster but it hardly changed while mine had started to visibly fade after the second/third session. I realise there are a lot of variables to consider here re: health etc. but thought worth mentioning.
