The world of aesthetic cosmetology and beauty is continuously evolving. And there’s always new devices or technology to aesthetically improve our appearance. However, the world of aesthetics tends to involve invasive procedures.
So what exactly is fat cavitation? Ultrasounds7–10: through the generation of compression and depression cycles at appropriate frequency, they cause cavitation phenomena at the fat droplet-watery cytoplasm interface and eventually adipocyte rupture and triglyceride release.7,9 Ultrasonic energy can be delivered by nonfocused or focused waves. With the nonfocused mode, due to depth-related ultrasound attenuation, the superficial skin is exposed to maximum energy intensity. By contrast, focused ultrasound can be concentrated in a defined subcutaneous area to produce clinically relevant fat lysis11,12 while limiting damage to blood vessels, nerves, connective tissue, and the underlying organs. However, the thermal effects of focused ultrasound energy may result in adipocyte necrosis in the treatment area (Bani et al., 2013). In simplified words, it basically means destroying fat cells through ultrasound technology by rupturing them. Doesn’t this sound nice?
