The particular laser clinic I’m looking at for tattoo removal uses a Focus Medical NaturaLase QS 2J. They combine this with a Zimmer Cryo 5 for cooling. They are only a tattoo removal shop and have excellent reviews. Is this a good machine? I want to be sure I do not get scarred and have great results which they said should take 8-12 for my half sleeve. I am vampire pale and my tattoo is black and grey American traditional style.
