I wanted to try radio therapy to tackle the lines from my nose to my mouth, as well as creases on the forehead. As an experiment, I've only treated one side of my face, including the jawline. I picked the side with the deepest nose-mouth line and I'm confident that I can see a difference. The line is not as deep or as long now. The untreated side appears to sag slightly more.
It has taken a few weeks. I have used the device without fail 3 times a week, as instructions suggest. The gel has a smell that I'm not keen on, but getting used to. I understand it will be expensive to replace but you use an extremely thin layer. Treatment is quick - it doesn't take a huge slice out of your daily routine. The device makes your skin fairly hot. This might not be to everyone's taste. I have not needed to go to the hottest setting, only medium.
On the forehead, it is tricky to use. There is a sensor in the middle of the four 'probes'. The sensor sticks out further than the metal probes and given that the forehead has no fat to it, the sensor digs in. I've persevered. It doesn't prevent use on the forehead but is certainly is not as easy to get the four metal points all touching the skin as it is with the cheeks.
I'm pleased with the purchase, will continue and expect that the results with continue. Of course, I will have to treat the other side to even things up!!
