What is useless! ! ! I've experienced it myself. I brushed my calf. My calf just started to thicken, 36 cm, and now it's 33, half a month. I bought a Capricorn brush and it hurts when I scrape the board. Moreover, the scraping board is mainly used for detoxification, mostly used in beauty salons, and Capricorn brush is specially used for slimming. But if you are all fat, I suggest you don't use scraping. Scraping is only used for local thinness. Let me explain the method. Prepare Capricorn brush and essential oil (any lubricating oil can be used, it must be difficult to absorb, and olive oil can also be used, but it will make your leg hair thick and long). You can also use stovepipe cream after brushing your legs, but I didn't buy it, and the student party didn't have enough funds. So I just used Capricorn Brush and Essential Oil. You can search Baidu video. If you brush, you should brush up and down quickly and forcefully. If you can feel your legs warm after brushing, it will work. Finally, wrap it in plastic wrap for 20 minutes. Then stick to it. Fight unarmed. I hope it helps you.
