First of all, you need to prepare plastic wrap, coarse salt, towels and other items, pat the coarse salt evenly on your thighs, rub the salt repeatedly on your thighs, poke a few holes in the plastic wrap with toothpicks and other tools in advance, and wrap the processed plastic wrap around your whole leg, which has a certain stovepipe effect.

After using plastic wrap, you can also use hot towel and ice towel to ice for one minute respectively. The temperature difference between hot and cold can make the effect of crude salt better. Apply it repeatedly for about five times, and after 15 minutes, you can open the plastic wrap and rinse it with water.

Usually, when using plastic wrap stovepipe, in the process of slapping crude salt, the legs should be wet first, otherwise the crude salt can't be slapped on the thighs, and it will take about a month to have obvious effect. If the plastic wrap stovepipe doesn't work for a month, then you need to replace other stovepipe methods.
