I've bought an IPL device a couple of years ago. It was a complete waste of money, the only thing that it did, was to slow down the growth of the hair, but the hair was still growing. The sessions were veeeeery veeeery long (took about an hour to make just one leg!), and there are some parts of your body that you simply CANT do by yourself because you can't reach them or are very difficult to reach. The laser treatments was a complete different story, I'm seeing permanent results and I'm very happy with it. The sessions are very faster (about 30/40 minutes my whole body except arms and face), and there is someone else doing the treatment so I dont have to make Yoga positions to reach the "hart to reach" parts of my body
Dont waste time and money with home IPL devices.
Hope this helps, sorry for my english
