I have not heard of any benefit from such of vibration machine after CoolScupting device. It is common for staff at the physician's office to massaged cool sculpting area right after the treatment is finished.
I am not certain to which vibration machine you are referring. Some physicians use a device called a Z wave machine to help with the massage after the CoolSculpting treatment. The Z wave does mechanical massage using sound waves. There are some physicians who prefer the Z wave machine while others perform manual massage instead.
