The milk used in the bathhouse is ordinary milk, and what you said is only temporary. Pushing milk can't whiten, and you should also use some body milk with whitening effect. You don't need to use it to rub milk every day. You can go to the supermarket once a week to buy that milk salt, which can exfoliate and whiten. Then apply lotion, and the skin will be very upset. The main ingredients of chocolate milk are toffee and cocoa powder, which are basically not absorbed by the skin. Normal rubbing milk, just use fresh milk or yogurt or milk salt. The mixed skin you mentioned can't be shown on the body. Only people's faces have mixed characteristics.
So MM, don't worry that rubbing milk will be bad for your health. I heard that rubbing milk often can lose weight.
