My boyfriend used it before. I bought it for myself on Taobao. I want to know how it works, so I need my boyfriend to help me try. This product is called Bello red pepper slimming massage gel. To be honest, it doesn't have much effect, and once it is put on, the skin will turn red, and people with bad skin will be allergic and get a lot of red spots. I think both men and women should lose weight or exercise directly. Don't use those diet products.
