I've toyed with various face exercise regimes but never stuck to any of them.
I found the book on Amazon and thought the exercises are doable and saw an they do an App with videos which talks you through every exercise and every repetition. This has been the clincher for me, having a voice telling me what to do.
I have been doing this for a couple of months now and I'm really seeing the difference.
I was looking tired, and haggard, it kind of crept up on me, lips thinning, down turned mouth, eyes full no matter how much sleep I had but now I look like a much younger, fresher me.
They do take time and commitment, 5 days a week, you can't expect overnight results in the same way any exercise regime takes time.
But then I have 50 years in this face so I have been prepared to put the work in.
