Emsculpt Body Contouring — HIFEM

Emsculpt at Aura Skin Spa San Francisco is the only FDA-cleared non-invasive treatment that simultaneously builds muscle and reduces fat, using HIFEM (High Intensity Focused Electromagnetic) energy to induce supramaximal muscle contractions — contractions that are physiologically impossible to achieve through voluntary exercise.

During a 30-minute session, the Emsculpt applicator delivers electromagnetic pulses that cause the targeted muscle to contract at 100% of its maximal capacity, approximately 20,000 times. This rapid, intense contraction pattern stresses muscle fibers in a way that exceeds what conventional resistance training can achieve, triggering deep metabolic changes in the muscle tissue: existing fibers undergo hypertrophy (enlargement), and new muscle protein…

Clinical data supporting the Emsculpt device shows an average 16% increase in muscle mass and 19% reduction in fat thickness in the treated area after the standard four-session protocol. These results continue to develop for two to four weeks after the final session as the muscle and tissue remodelling process matures. Patients with an active exercise routine and stable body weight tend to achieve and maintain the best outcomes.
