This product does what it says... it removes tattoos and skin spots. I have a ring that I have spent $450 for three laser removal sessions. The last one did very little, so I tried this. The first treatment appears to have removed about 10% more and it didn't hurt nearly as much. I also tried this on a few skin growths and they are now gone. Wear glasses to avoid eye damage and earplugs if loud beeping bothers you. Those last two aren't a reason to give a poor review... Happy with my purchase and I would recommend.
