Oh, it's useless. I have used it myself before. Those in the WeChat business are really, really brainwashing. I believe them every day. It's useless after buying it. Apply the slimming cream to the calf and massage for half an hour at a time. It will be useful after a long time, and the legs will be 0.5cm thinner. It's really useless to just apply those without massage. Or eat less and exercise more to restrain yourself from losing weight. I hope my answer is useful to you.
