HIFU (High-Intensity Focused Ultrasound) is a technology that uses focused ultrasound waves to reach the deeper layers of the skin without damaging its surface. In aesthetic medicine, it is used to support processes such as tightening and improving skin structure. The method is part of the growing interest in non-invasive therapies that do not require surgery or a long recovery period.
High-intensity focused ultrasound (HIFU) works by directing ultrasound waves to specific layers of the skin and underlying tissues. Unlike traditional ultrasound used for diagnostic purposes, HIFU concentrates the energy in a small area, creating high temperatures deep below the skin's surface. This thermal stimulation causes controlled tissue damage, which stimulates the body's natural healing process.
By reaching the SMAS (superficial muscular aponeurotic system) layer – a structure typically treated in a surgical facelift – the cosmetic procedure results in tightening and slight lifting of the skin.
The immediate contraction and tightening of collagen fibers in the HIFU procedure is due to the thermal effect of ultrasound energy. When the ultrasound pulses penetrate the skin and reach the deep layers of the dermis or even the superficial muscular aponeurotic layer (SMAS), they increase the local temperature to about 60-70°C. This thermal energy causes denaturation of collagen molecules - a process in which the triple helical structure of collagen is temporarily disrupted.
As a result of the ultrasonic thermal effect, collagen fibers contract and compact, which leads to instant lifting and skin tightening. This is the visible short-term effect of the HIFU procedure. In addition, the thermal effect stimulates fibroblasts - cells in the dermis responsible for the synthesis of new collagen and elastin. It is this process that leads to long-term improvement in skin texture and elasticity within the next 3 to 6 months.
The cosmetic procedure is performed using a specialized device that produces ultrasound pulses of different frequencies and intensities. Depending on the area being treated, the ultrasound penetrates to a depth of 1.5 to 4.5 millimeters. When treating areas of the body with a thicker subcutaneous layer, such as the thighs, abdomen and hips, specific tips are used that can penetrate to a depth of 8 to 13 millimeters.
One of the key aspects The effectiveness of HIFU is due to the ability to precisely adjust the parameters to the individual characteristics of the patient. It is important that the procedure is performed by qualified specialists who can assess the condition of the skin and determine the most appropriate treatment plan.
Tightens the skin in the area of eyebrows, cheekbones, jawline and neck, creating a “V-shaped” shape. Reduces sagging skin on the neckline, breasts and other parts of the body.
Ultrasound penetrates through the deep layers of the skin to the SMAS layer – the superficial musculo-fascial layer, activating the synthesis of new collagen.
There is no recovery period required. There may be slight redness and swelling for a few hours.
Suitable method for all skin phototypes, including dark skin, unlike some laser procedures.
The effect lasts 1–2 years, depending on age and post-procedure care.
Reduces cellulite and slight sagging skin on the abdomen, buttocks, thighs and arms, for example after weight loss.
