the other advice is mentioned here i think it’s Tria so if you plz tell are they effective or not. thank you.

Please run a search on the forum. All these devices have been previous discussed in numerous threads. So far, there have been no individual reports of any home machines actually producing permanent results. If they did, we’d all be using them instead of paying for professional treatments.
