What is Body HIFU and how does it work?

Body HIFU, or High-Intensity Focused Ultrasound, is an advanced medical technology for body contouring and skin firming. This non-surgical treatment uses ultrasound waves to penetrate the deep layers of the skin, reaching the adipose tissue and superficial muscular fascia. The ultrasound energy generates controlled heat, which has a dual effect.

Firstly, it causes the contraction and tightening of existing collagen fibers, resulting in an initial improvement in firmness. Secondly, it stimulates the long-term production of new collagen and elastin (neocollagenesis and neoelastogenesis). Additionally, in the deeper layers, this heat can selectively destroy fat cells, contributing to volume reduction.

Application areas and benefits

Body HIFU is versatile and can be applied to various areas where skin has lost firmness or where localized fat accumulation exists. Common areas include the abdomen, arms, knees, flanks, and thighs. It is an effective alternative for those seeking to improve their silhouette without resorting to invasive procedures.

HIFU for Abdomen

In the abdomen, HIFU helps tighten sagging skin, especially after pregnancy or weight loss. It also helps reduce the localized fat layer, improving the contour of the area. The goal is a firmer, more defined appearance.

HIFU for Arms

The arms are a frequent area of concern due to sagging, known as "bat wings." HIFU firms the skin on the inner arms, improving skin texture and tension. Results vary depending on the initial skin laxity.

HIFU for Knees

The skin above the knees can show sagging and wrinkles over time. HIFU treatment in this area aims to tighten the skin, providing a more youthful and smooth appearance. It is a precise approach to improve the aesthetics of this area.

The procedure: What to expect?

Before starting the treatment, a detailed medical evaluation is carried out to determine the patient's suitability and establish the areas to be treated. During the session, a conductive gel is applied to the skin and the Ultraformer MPT device head is used. This emits ultrasound pulses in a controlled manner.

Some patients may experience a slight sensation of heat or small pricks during the procedure, which is generally well tolerated. The duration of the session varies depending on the extent of the treated area, but usually ranges from 30 to 90 minutes. It requires no downtime, allowing you to resume daily activities immediately.

Results and timeline

The results of body HIFU are not immediate, as the neocollagenesis process is gradual. Many patients observe an initial improvement in skin firmness in the weeks following treatment. However, the most significant effects usually appear between 2 and 3 months after the session, as the body produces new collagen.

The duration of results may vary, but generally lasts for 12 to 18 months. To optimize and prolong the benefits, maintenance sessions may be recommended. The number of necessary sessions is defined in the initial medical consultation, according to individual needs.
