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

Abstract

HIFU safely and effectively improves skin elasticity and clinical contouring of the face and body.

Nerve injury associated with high‐intensity focused ultrasound: A case report

“…It is estimated that the device heats tissue to the critical temperature of 65‐75°c at which collagen denaturation occurs and stimulates the tissue repair cascade. Collagen contraction and remodeling occurred around microcoagulation zones can cause skin tightening on treated area . Wondergem et al reported the effect of local heat treatment on the motor function of the rat sciatic nerve at the temperatures from 42‐45°c resulting in motor function evaluated using the toe‐spreading test.…”

“…In 2009, FDA approved the use of HIFU for eyebrow lifting, followed by a neck and submental lifting. However, off‐label applications for facial rejuvenation, skin whitening, hyperhidrosis, acne, and lipolysis have been employed . The tightening effect of HIFU is the result of transcutaneous coagulative heating to specific area of the dermis and subcutaneous tissue.…”

“…The tightening effect of HIFU is the result of transcutaneous coagulative heating to specific area of the dermis and subcutaneous tissue. Dermal collagen regeneration is induced by this coagulation effect without surface skin damage . Recent studies demonstrated safety and efficacy of HIFU at 73%‐90% improvements of skin laxity on facial and neck areas .…”

Review of non‐invasive body contouring devices for fat reduction, skin tightening and muscle definition

“…The focal depth and energy output on these devices can be adjusted based on the thickness of the patient's facial and body skin, which ultimately determines the treatment outcome . Each procedure lasts for approximately 30–90 min, depending on the treatment location on the body.…”

Reduction of abdominal skin laxity in women postvaginal delivery using the synergistic emission of radiofrequency and targeted pressure energies

“…The demand for noninvasive esthetic procedures for skin tightening increases. Technologies such as Radiofrequency (RF), High‐intensity Focused Ultrasound (HIFU), Laser, Infrared IR), and pressure energy devices are used to improve the esthetic appearance and self‐confidence of patients.…”
