CoolTone CoolTone is Available Now! THE NEXT DIMENSION IN BODY CONTOURING HELLO COOLTONE™ Allergan®, the leading company in medical aesthetics,¹ introduces the CoolTone device, the latest innovation to its body contouring portfolio. CoolTone’s Magnetic Muscle Stimulation, or MMS technology, penetrates through the skin and fat layers to target only the muscle layer, inducing involuntary muscle contractions. The body’s response to these contractions is to strengthen its muscle fibers, resulting in improved muscle conditioning. After treatments, abdomen, buttocks, and thighs are firmer and have a more defined and toned appearance.
