I always use edible salt. If conditions are good, you can buy special bath salts. Choose smaller particles.

I always use salt+milk+honey+olive oil+essential oil. These samples can be combined freely, as long as you master the quantity yourself. Rub it on your body when you take a shower. Then go for it. The body will be slippery.

If you want to lose weight, you can massage more places where lymph nodes gather.
