I used it, and my skin felt ulcerated, because all the products contained capsaicin, which was unbearable at first. It can be mixed with any other oily massage cream without affecting the effect, because massage is the main way to lose weight, and others only play a lubricating role. If you are using it yourself, you'd better go to a weight-loss hospital for massage, but it depends on what you can stand. After a few times, you get used to it. The light at home feels like a fever, but it doesn't work at all. You will know that this is their website. You can go to www.wgbxj.cn, where there are many slimming products. I hope I can help you.
