Brushing the body is to dredge the meridians and expel toxins. Pain shows that your meridians are not smooth, and it is normal to have bruises on the brushed areas. What's more, the brush is right, and the strength is definitely greater than the carelessness. There are lumps in serious places because there is fat accumulation inside. Brushing a few times can not only dredge the meridians, but also lose weight. Although it hurts a little, it does have an effect and is good for your health. Give advice to yourself and the beauty salon girl next time. After menstruation, it is also a kind of detoxification for you, because the whole body meridians are unobstructed and the blood gas is unobstructed. When you come to menstruation, it will just help you excrete excess toxins in the uterus. Don't worry!
