The flow constantly changes polarity, heat is generated mainly by the friction of bipolar molecules. The water is the substance of the organism that more dipolar molecules have, therefore, the current acts on the tissues that contain greater content in water mainly muscular and vascular.

The electric flow enters into the body more directly. In this case the temperature increases in tissues and with greater electrical resistance on adipose tissue. The resistance of the fat is about ten times higher than that of the dermis tissue. In this case, the thermal effect in adipose tissue and cell membranes predominates.

In this case, the treatment electrode has an output electrode and a return electrode embedded in the same head-tip, so that the flow is in constant movement from one pole to the other.

The therapies in which we apply LED light are known as Photodynamic Therapies. Photoporation is another technique that helps the care of our skin. Red light is what will act as anti-wrinkle and as skin rejuvenation therapy. Infrared use long wavelength, so they can penetrate deep into the skin. So, Fibroblasts are activated, which are responsible for the formation of Collagen and Elastin.

Radiofrequency is an electromagnetic emission which is transformed into a thermal energy.

The Diathermy generates a deep cellular activation with the following three essential effects.
• Athermics: increase cellular metabolism Activate cellular nutrition
• Thermics: increase of micro-circulation, Improvement of blood flow, Activates tissue oxygenation, Promotes drainage
• Hiperthermics: improves blood flow Activation of metabolism, Drainage of catabolic products Tissue restructuring
