How does HiFu help fight loose skin and localized fat?

As we age, after significant weight loss, or as a result of other physiological changes, the body's skin can lose its firmness and elasticity. Localized fat deposits can also be a challenge, as they are resistant to diet and exercise. High-frequency focused ultrasound (HiFu) is emerging as one of the preferred non-invasive technologies for skin tightening and fat reduction.

How does HiFu work on skin and fat cells?

HiFu uses high-intensity focused ultrasound waves that penetrate different layers of the skin and subcutaneous fat without damaging the surface layer. Depending on the area being treated, the device reaches different depths – from 1.5 mm to 4.5 mm for skin tightening and up to 13 mm for fat reduction.

The procedure creates multiple thermal coagulation points where the temperature temporarily rises to 60-70°C. This results in:

• Skin tightening – the thermal effect causes immediate contraction of collagen fibers, and in the long term stimulates the production of new collagen and elastin, which improves the structure and elasticity of the skin.
• Degradation of fat cells – in the deep layers, ultrasound energy causes lipolysis (breakdown of fat cells), with the broken down fats gradually eliminated from the body through the lymphatic system.

What results can be expected?

HiFu can be effective for tightening skin in areas such as the abdomen, arms, thighs, knees and buttocks, as well as for contouring by reducing localized fat deposits. However, it should be borne in mind that results develop gradually over 2-3 months as the body synthesizes new collagen and eliminates the broken down fat.

It is important to emphasize that HiFu is not a substitute for surgical interventions and cannot provide drastic results such as liposuction or surgical facelift. The best results are observed in people with moderately loose skin and localized fat deposits who maintain a healthy lifestyle.
