CoolTone is made by Allergan, the same manufacturer that developed the CoolSculpting device. The two are a perfect complement. CoolSculpting has been one of the leading devices for non-invasive fat reduction for the past several years. Now comes CoolTone, which is used to tone muscles deep beneath the skin. The two work differently. To reduce fat, CoolSculpting emits freezing temperatures into adipose tissue. This causes fat cells to crystallize. The damage results in their elimination through the lymphatic system. To tone muscles, CoolTone emits controlled electromagnetic energy that passes through the layer of fat to constrict the muscle fibers beneath them.
