Yes, apply a little (too much will be unbearable spicy, and the skin will be very hot, but it will not hurt the skin). Where you need to lose weight, brush back and forth with "Five Elements meridian brush" to break up your fat. Strong muscles can soften your muscles. When you brush them to the frosty place, your skin will start to turn hot and red. Brush them for about 10~ 15 minutes. Then if you can't stand the heat, wipe them off with alcohol cotton and then wash them with water. If you want to lose weight quickly, this is feasible. If you have a treadmill at home, run for half an hour. If you are a girl, don't run (if you don't want to be a muscle girl). Adjust the speed to about 5.3 and start walking at a brisk pace until the heat is unbearable and there will be oil and sweat on it when it is torn off, and then wash it off. After exercise, relax your muscles, put your legs on the bed, put your feet on the wall, and straighten your toes to let blood flow back.
