I have noticed a positive difference in the feel of my skin and it does feel firmer, especially on my forehead which is tighter. I found it best to gradually build up the intensity, but I managed to go quite high. It’s a strange sensation, and your face is scrunched up with muscle contractions, which I imagine looks quite amusing! The treatment is certainly worth trying, especially if you don’t want to go down the botox/filler route as it’s working your own muscles and increasing collagen production.
