# Effect of Tecar Therapy in the Treatment of Skin Flaccidity and Localized Abdominal Fat—Clinical and Controlled Study

## TL;DR

This study shows that tecar therapy safely reduces abdominal fat and improves skin flaccidity through thermal energy.

## Contribution

The study provides clinical evidence for tecar therapy's efficacy in aesthetic treatments for skin and fat.

## Key findings

- Tecar therapy reduced localized abdominal fat and improved skin flaccidity in treated subjects.
- Histological analysis revealed adipose tissue degeneration and new blood vessel formation in treated tissue.
- Results were confirmed through anthropometric, adipometric, and ultrasound evaluations.

## Abstract

It is known that when an electrical stimulus is greater than 10 kHz, our body converts this electrical energy into thermal energy, and due to this fact, one of the therapies that has been showing good results is therapeutic, capacitive, and resistive energy transfer (tecar therapy), but there is still little evidence about its action on area of aesthetics. Therefore, the objective of this study was to evaluate the safety and efficacy of tecar therapy for the reduction of localized fat and improvement of skin flaccidity in the abdomen region. A controlled clinical trial was carried out with 48 women equally divided into 2 distinct groups, with (G‐1) received treatment with tecar therapy and (G‐2) considered the control. Ten treatment sessions were performed once a week. The volunteers were evaluated at three different times using anthropometric data, adipometry, and ultrasound (US), in addition to histological analysis of the adipose tissue performed on one of the volunteers. In the results of the adipometry and US, a decrease was observed both in the comparison between the groups and between the baseline and the end of the treatment for the supra and infra umbilical region. In the histological analysis, it was observed that the G1 showed positive markers for moderate chronic inflammation, indicating degeneration of the adipose tissue with a large number of fibroblasts and newly formed blood vessels in the integumentary tissue. With this, it was possible to conclude that tecar therapy proved to be a safe and effective resource in the treatment of sagging skin and reduction of superficial adipose tissue.
