Diathermy generates heat in the tissues through capacitive and/or resistive transfer, resulting in a biological and chemical-electrical activation that favors tissue healing through the movement of the electric charges present in our body.

What is diathermy for?

Known as Tecar therapy and used with great success in sports medicine, diathermy stimulates the reabsorption of edema and blood effusions in the event of trauma, removes inflammation and relaxes the muscles.

However, its effectiveness has also proven to be equally impressive in advanced aesthetics, both for the face and body, because it improves skin tone, reduces wrinkles and swelling (from bags under the eyes to the ankles), reshapes the silhouette and improves stretch marks.

How diathermy works

During diathermy treatment, energy is conveyed through two different types of transfer with metal electrodes of different sizes.

  • Capacitive transfer: releases energy in the first layers of tissue, regardless of any impedance it encounters, extensibility draining and improving muscle tone. The electrodes are coated with insulating material so the therapist’s movements will be faster. Capacitive diathermy works on edema and improves tissue tone: in particular, it stimulates fibroblasts, those cells in our dermis (responsible for the production of collagen and elastin), which become sluggish after the age of 25.
  • Resistive transfer: releases energy into deep tissues with high impedance, i.e. those poor in water (bones, cartilage, large tendons, aponeurosis), reactivating the metabolism. In this case, the therapist’s maneuvers are slower. Resistive diathermy acts on localized fat deposits and hard cellulite.

Benefits of diathermy

Diathermy is completely natural: the therapist uses just a conductive cream to facilitate the sliding of the handpiece on the skin. For this reason, the treatment is suitable for all patients, at any age, with the exception of some contraindications.

This method promotes the development of endogenous energy in the treated area by recalling the natural electric charges: in fact, the handpiece itself is cold and the heat that the patient feels is, precisely, endogenous. The treatment feels very pleasant and relaxing.

Thanks to the three different reactions that can be induced – microcirculation, vasodilation or temperature increasement – diathermy can accelerate cellular metabolic processes both in the case of pathology, and in terms of prevention and “regener-age”.

Diathermy allows your skin to be more toned and compact, also leading to the reduction of wrinkles, cellulite, edema and swelling, as well as the improvement of silhouette and stretch marks.

In summary

For whom it is appropriate

Resistive diathermy is appropriate in cases of hard cellulite and localized fat; capacitive diathermy in case of soft cellulite, skin and muscle laxity, swelling, edema, stretch marks.

Problems handled

Hard and soft cellulite, skin laxity and withered, wrinkled and sagging skin (also on the face), swelling (including those that generate bags under the eyes), edema, stretch marks.

Non-invasive – 1 handpiece with capacitive or resistive electrode plus 1 conductive plate.


30 minutes if the area to be treated is limited; 50 minutes on large areas like abdomen, arms, etc.

Number sessions and frequency

6-8 sessions every week or less, as needed.


Drink plenty of water to help eliminate fluids.
