Radio frequency is a technology that allows the selective application of electromagnetic energy to the deep dermis. It achieves it from the surface of the skin and thus be able to fight against flaccidity, body cellulite and favor the elimination of fat.
Within this electric field, the polarities change from positive to negative alternately, which causes great heating of the tissues. This heating generates an increase in circulation, a stimulus to the fibroblasts for the formation of neo-collagen and an increase in cellular metabolism, ideal for toning the tissues, eliminating superficial wrinkles and attenuating deep ones, and notably improving the appearance of stretch marks and scars.
It is an incredible ally to obtain good results in aesthetic treatments, and thanks to its technique, it manages to promote the natural production of collagen in our body, and therefore, recover the tension in the skin, fill wrinkles, and recover that aspect hydrated and fresh in a totally natural and beneficial way for us. With which we get firmer skin, eliminating flaccidity.
Types of Radio Frequency
Capacitive RF: It is distinguished by having its electrode covered by an insulating material that prevents direct contact of the metal with the skin, which produces effects on more superficial tissues. The electrode directs its energy to the return plate.
Monopolar Resistive RF: It consists of a metal electrode that provides direct contact with the skin as it lacks any insulator. The resistive radiofrequency produces effects in the deeper tissues since, thanks to its direct contact with the skin, it can go deeper. The electrode directs its energy to the return plate.
Bipolar Resistive RF: It consists of an electrode that contains two polarities (positive and negative) that can be expressed by two or more circles or metallic tips. Like the previous electrode, it provides direct contact with the skin, but its action is more superficial since it lacks a return plate. This means that the energy does not travel through the whole body but only moves superficially, through its different polarities.
Radio Frequency and its Application in Aesthetics
This method is based on a High-Frequency current (greater than 1 MHz) with low voltage, but high intensity. The main effect of this radio frequency is to create an increase in temperature in the dermis. This is intended to reach temperatures between 40ºC and 45ºC and in no case exceed 50ºC since the skin would become necrotic.
With these temperature traits, the dermis generates the so-called Heat Shock Proteins. These are proteins that instantly compact the collagen and elastin fibers, thus causing an immediate lifting effect on the skin. Heat shock proteins reactivate and stimulate fibroblasts, which are found in connective or connective tissue. In this way, the production of collagen and elastin in the skin is considerably increased. This restructures the dermis and offers greater elasticity and firmness.
Monopolar Radio Frequency
In the case of monopolar radiofrequency, the head of current emission and reception are not in the same handpiece. The receiver is usually a backplate or a handheld receiver. It is a more intense type of radiofrequency and the warm-up time is noticeably faster. Although penetration into the tissue is greater with this technique, it can be somewhat painful. In older people, the radiation emitted spreads somewhat uncontrollably throughout the body.
Bipolar Radio Frequency
When it comes to other types of radiofrequency such as bipolar, the current emission head and the reception head (s) are in the same handpiece. This type of treatment is more superficial and the heating is more controlled than in monopolar radiofrequency. This means that you can work to solve a problem in a more localized way and with greater control.
To obtain results with radiofrequency technology, 4 to 6 sessions are generally necessary, the duration of which is usually about 10 minutes for the facial area, while for body treatments, 6 to 10 sessions are required with a duration of approximately 30 minutes. In any case, it is a simple procedure for the patient, minimally invasive and without the need for anesthesia. The number of sessions is somewhat indicative since it varies depending on the previous state of health of the skin of each person, as well as the area in which the radiofrequency is to be applied.
