Tightening effects of high‐intensity focused ultrasound on body skin and subdermal tissue: a pilot study

Abstract

For body tightening, we applied HIFU using transducers with a lower frequency and deep focal depth to effectively deliver ultrasound energy to skin tissues. HIFU appears to be a safe and effective treatment modality for dermal and subdermal tightening.

Efficacy and safety of non‐invasive body tightening with high‐intensity focused ultrasound (HIFU)

“…Injection lipolysis and cryolipolysis have significant potential for AEs, which is largely unregulated and may cause significant pain, hematoma, allergic reactions, necrosis, scarring, panniculitis, and rapid release of lipids into the bloodstream. In contrast, previous clinical studies supported thermal HIFU for body sculpting have had no serious AEs including alterations in lipid profiles or other laboratory parameters . Therefore, many clinician are keeping an eye on the HIFU technique as purpose of body sculpting.…”

“…HIFU has been used safely and effectively to treat facial and neck skin in a variety of skin types, but some studies have examined its use for the body, including our pilot study . In this study, we sought to determine the clinical efficacy and safety of HIFU with novel transducers in both face and body regions.…”

Role of mechanical and thermal damage in pericapsular inflammatory response to injectable silicone in a rabbit model

“…The injection sites were then subjected to HIFU treatment to demonstrate that the application of an external force can stimulate capsular inflammation at the injection site. HIFU is currently used clinically for skin and subdermal tightening, and no adverse effects have been observed when it is used on normal skin [12–14]; unlike other invasive procedures (e.g., needling), it has minimal effects on the epidermal layer. Consequently, there are no concerns with regard to bleeding or infection from the resulting damage.…”

“…Consequently, there are no concerns with regard to bleeding or infection from the resulting damage. Furthermore, the depth and intensity of the damage can be controlled, which allows the application of mechanical and thermal damage to a localized region surrounding the foreign body without undesired effects from other factors [12, 13, 15]. In the present study, we performed multiple tests to precisely target the injected silicone using HIFU without affecting the normal tissue, and determined the optimal intensity and depth of HIFU (4 MHz, 4.5 mm).…”

Subcision™ plus poly‐l‐lactic acid for the treatment of cellulite associated to flaccidity in the buttocks and thighs

“…Some published and other ongoing studies have demonstrated the efficacy, low‐complexity and well‐established safety of treating patients who have aesthetic concerns regarding their bodies . The most widespread methods involve technologies such as radiofrequency, macro‐ and micro‐focused ultrasound, and lasers .…”
