I can't offer any personal experiances...but my daughter is due to have her first session to have a tattoo removed. Hers is on her upper arm,aproximately 4cm deepand very dense and dark. One session is going to cost her �130....I don't know how many she will need. the price I mention is in London. I suppose it may be cheaper elsewhere.
not really an answer to your question , but i was saw an article in the back of a magazine yesterday about a cream that fades tatoos almost completely in 6 months. not a quick fix, but would not be as painful as laser removal
