Used only once. It gets hot enough to make you sweat, and I think it has a tightening effect. If you have sensitive skin, you may experience itching, so it is recommended to gradually adjust the amount you use. The scent is soft, but it doesn't last long, so you can use it without clashing with the scent of your shampoo, etc. The exterior has been cleaned and wiped, and will be shipped in simple packaging!
