When I tried the GLOPulse ($165), I was surprised to learn that the machine is very straightforward to use. First, you put on the coordinating sheet mask. Then you place the device over your head like you would put on headphones. Finally, you simply press the power button to start the treatment (you can increase the intensity by pressing that same button once or twice). Twenty minutes later, the device turns off.
The most impressive part: afterward, I didn't even want to wear makeup because my skin was so glowy. In my opinion, this is the perfect facial if you want radiant skin, fast.
