What is CoolTone?
CoolTone is an FDA-cleared, non-invasive body contouring and muscle-strengthening device developed by Allergan Aesthetics. It uses proprietary Magnetic Muscle Stimulation (MMS) technology to deliver a powerful, focused magnetic field to the targeted treatment area. This field penetrates through the skin and fat layers to directly engage the underlying muscle tissue, inducing rapid, intense muscle contractions known as supramaximal contractions. These contractions are significantly more powerful and more frequent than what the nervous system can voluntarily produce during exercise.
During a single 30-minute CoolTone session, the targeted muscles undergo thousands of these contractions, triggering the same adaptive response that strength training produces, but at an accelerated rate and intensity. Over a series of treatments, the muscle fibers remodel and reinforce, resulting in increased muscle density, improved tone and firmness, and measurably greater functional strength.
CoolTone is the only device of its kind with FDA-cleared indications that extend beyond aesthetics. In addition to aesthetic toning of the abdomen, buttocks and thighs, CoolTone’s updated 2026 FDA indications specifically recognize its ability to improve muscle performance and facilitate muscle training, prevent and reduce disuse muscle atrophy, support lower extremity rehabilitation, relax muscle spasms, increase local blood circulation, assist with muscle reeducation and learning and help maintain or increase range of motion. This makes CoolTone uniquely positioned as a treatment that benefits patients across a broad spectrum of goals, from competitive athletes to active aging adults.
