For years, aesthetic surgeons have sought effective solutions for reshaping the lateral abdomen, or “flanks,” an area where stubborn fat and muscle deconditioning pose significant challenges. Traditional options such as liposuction and cryolipolysis address fat but fail to enhance underlying muscle tone. However, a recent study in the Aesthetic Surgery Journal introduces a groundbreaking, noninvasive approach: the simultaneous application of high-intensity focused electromagnetic (HIFEM) therapy and synchronized radiofrequency (RF). This novel dual-modality treatment offers promising results for both fat reduction and muscle toning. Let’s take a closer look at the findings.

The Challenge of Flank Contouring

The lateral abdomen significantly impacts core stability, posture, and overall aesthetics. Excess fat in this region, often referred to as “love handles,” can distort the abdominal profile and make it difficult to find well-fitting clothing. Genetics, diet, and hormonal factors all contribute to the stubborn nature of flank fat, while muscle atrophy exacerbates poor posture and diminished core strength.

Traditional interventions, such as tumescent liposuction, while effective for fat removal, require downtime and carry risks of swelling and complications. Cryolipolysis, a noninvasive fat-freezing method, targets adipose tissue but lacks the capacity to improve muscle strength. Enter the dual-modality HIFEM + RF therapy, which not only reduces fat but also strengthens the oblique and transverse abdominal muscles.

The Study: Evidence-Based Results

This multicenter MRI-based study evaluated the safety and efficacy of HIFEM + RF for flank sculpting. Seventy-three patients underwent four 30-minute sessions over four weeks, with follow-ups at one and three months post-treatment. Using MRI, researchers measured changes in muscle cross-sectional area (CSA) and fat thickness.

Key Findings in the Study:

  • Muscle Development: A 29.0% increase in muscle CSA and a 27.2% increase in thickness were observed, signifying substantial improvements in muscle tone and core stability.
  • Fat Reduction: The treatment achieved a 30.5% reduction in fat CSA and a 28.8% decrease in thickness, highlighting its efficacy in reducing stubborn flank fat.
  • Patient Satisfaction: Over 81% of participants reported feeling more toned, and 84.9% found the treatment comfortable, with minimal pain reported.

Mechanisms of Action: HIFEM and RF

HIFEM technology induces supramaximal muscle contractions, far surpassing the intensity of voluntary exercise. These contractions stimulate muscle growth and strengthen muscle fibers, enhancing overall core stability. RF complements this process by generating heat that targets adipose tissue, leading to apoptosis (cell death) without inflammation. Together, these modalities create a synergistic effect, sculpting the flanks while improving muscle tone.

This dual-modality treatment offers several distinct benefits over traditional methods:

  1. Comprehensive Results: Unlike liposuction or cryolipolysis, HIFEM + RF addresses both fat reduction and muscle strengthening, providing a holistic contouring solution.
  2. Noninvasive Approach: With no incisions or downtime, the treatment appeals to patients seeking effective yet minimally disruptive solutions.
  3. Improved Confidence: Participants reported feeling more comfortable in their clothing, an essential psychological boost that underscores the aesthetic and functional benefits of the treatment.

By addressing both fat reduction and muscle strengthening, this dual-action treatment of HIFEM + RF for flank contouring meets the growing demand for noninvasive yet effective solutions. Aesthetic surgeons now have a powerful tool to enhance their patients’ outcomes and expand their practice offerings. The next frontier lies in refining treatment protocols and further exploring the synergistic potential of these technologies. For now, HIFEM + RF offers a compelling option for patients and practitioners seeking transformative yet safe and efficient contouring results.
