Tone, strengthen, and firm your muscles with CoolTone! This nonsurgical FDA-cleared treatment tones and strengthens your abs, glutes, and thighs. CoolTone uses a Magnetic Muscle Stimulation, or MMS technology that 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 the abdomen, buttocks, and thighs are firmer and have a more defined and toned appearance.
