A local med spa offers Emsculpt treatments (marketed as Emsculpt) for a surprisingly low price (325 a session USD). When I asked , they said it was because they had already paid off the machine. Is there any way to determine whether or not it is real? Can I ask for a certificate of authenticity? The machine looks like Emsculpt machines but it doesn't have the logo, it has the med spa's name on it.
