A study found that the use of ultrasound and high-frequency devices together is effective in improving abdominal obesity.

Professor Jeon Hye-jin (corresponding author) and Professor Son Yeo-ju (first author) of the Department of Family Medicine at Ewha Womans University Seoul Hospital recently published a study titled 「Ultrasound and High Frequency Equipment Efficiency for Abdominant Oobility Reduction in Women」 in the Nature sister journal 『Scientific Reports』.

The research team analyzed changes in waist circumference and abdominal fat volume before and after simultaneous treatment of ultrasound-based body contouring (UltraSpeed™ handpiece) and high-frequency-based skin tightening (UniBody™ handpiece, life prescription: UniForm™) on nine Korean women aged 18 or older who visited the Well-Aging Center at Ewha Medical Center in 2023.

As a result, the average waist circumference decreased by 3.83 cm (4.35%), and the subcutaneous fat area also decreased by an average of 18.90 ㎠ (7.19%). On the other hand, there was no statistically significant change in visceral fat area, suggesting that the procedure was mainly effective for subcutaneous fat.

"One of the reasons why patients easily get tired and frustrated during obesity treatment is that visceral fat decreases relatively quickly in the early stages of weight loss, but subcutaneous fat decreases at a slow rate, causing noticeable changes," the research team said"The results of this study are significant in that ultrasound and high-frequency parallel procedures can effectively reduce subcutaneous fat so that patients can experience visible changes more quickly, thereby increasing motivation and clinical satisfaction for obesity treatment."

He added that "Further studies on protocol optimization and long-term effects are needed to increase the safety and effectiveness of non-invasive procedures in the future."

Meanwhile, this study was led by Professor Jeon Hye-jin (corresponding author) and Professor Son Yeo-joo (first author) of the Department of Family Medicine at Ewha Womans University Seoul Hospital, and is significant as it presents the basis for the latest non-invasive body correction treatment in the domestic medical beauty field.
