I’ve only just started using this product and apparently it takes 12 weeks to notice a real difference so it’s really impossible to say at the moment. I can say that it is perfectly bearable to use, even though are use it on my face and the face gets hot where you are using it, but as I said, it’s completely bearable and not really painful. And it seems to do what it supposed to do according to the instructions. I’ll just have to wait and see
