High-intensity focused ultrasound (HIFU) application is a new method which has recently become popular within the aesthetic applications. It enables skin tightening. This method is also known as non-surgical face lifting. It can be also used for tightening purposes on the face, neck round, and other areas, such as arm and interior parts of the legs.
The HIFU is pain-free and can be applied in the office setting. As the main advantage, it uses ultrasound, which has been used as a diagnostic tool for many years and is known as completely safe without leading to any side effects. The application often takes one hour. Ultrasound energy accumulates in the subcutaneous tissue and is converted to thermal energy, by producing tension zones in the muscle fascia. As a result of this effect, sagged tissues can be reconstructed and a number of wrinkles can be reduced. It is pain-free, and it does not cause redness or skin discoloration. Its effect starts immediately following the application, although the full effect can be observed within three months.
