Do Tattoo Anesthetics work?

I just wanted somw feed back before I purchased some and wanted to know if there is (the Best) a certain kind that would work best. thanks ....I have always done them the old fashioned way but have a full back piece and would like to atleast get through the entire outline the first go round

I've had good experience with super juice and bactine. Both are best if you let them set for about 15-20 minutes. Also one of our artists tried something new this week, filled his rinse cup with half water, half bactine, and the client said it made a world of difference! Both are kind of expensive though, so if anything I'd tell your clients to pick it up for themselves (bactine that is) at a pharmacy near by. Otherwise you'll be dropping lots of dough!
