Although I haven't used it before, I think it's best not to use this product. Generally, it is because the skin is irritated and reddened, and the skin on the stomach is relatively thin, which makes it easier to get hurt. Generally speaking, you should not use this condition again. It will be all right in a few days. If it is not good, it is recommended to see a doctor. The best way to lose weight is to exercise and pay attention to diet!
