The slimming principle of slimming cream is that you need a lot of massage, because ordinary slimming cream needs you to massage, but even if you don't apply it in advance, you can slim down after 30 minutes of massage, so there is no need to buy slimming cream. As for the burning sensation during massage, it is also because of hand massage, which has nothing to do with slimming cream. It is recommended that you massage your abdomen twice a day or 1 time for 30 minutes each time, because the time is too short and the effect is not good. Turn up, left, down, right and left hand clockwise, because pressing it with one hand for 30 minutes takes a lot of effort.
