Radio Frequency Handle

How Does a Radio Frequency Handle Work?


Monopolar radiofrequency is one of the most common aesthetics technologies that tightens skin and contours the body. The RF energy heats the tissue below the skin, stimulating collagen and elastin production and resulting in wrinkle and laxity reduction. The treatment can also shrink fat cells by disrupting their membranes and triggering the release of fatty acids and glycerol. RF treatments can be used on any skin type and are safe for all skin colors, but they are especially effective in the middle and lower face.

During the procedure, the monopolar handpiece delivers an electromagnetic current through a single electrode on the tip of the applicator and back to a grounding pad that is connected to the device at some distance from the applicator. This method generates volumetric heating that heats the deep dermis, fibrous septae, and fascia and induces immediate collagen contraction. The effect lasts for 4-6 months.

The bipolar RF technology has two electrodes on the same handpiece and emits a radiofrequency current with the polarity opposite that of the monopolar applicator. As a result, the RF current can penetrate more deeply in all skin layers, including the deeper tissue (hypodermis and Radio Frequency Handle subdermis), causing ionic molecular vibration or water molecular rotation, depending on RF frequency and the electrodes’ position. Bipolar RF devices also offer greater control over the application of energy and better distribution, compared to monopolar or unipolar RF devices.


Bipolar RF devices use two electrodes without a grounding plate. The energy is passed precisely between the electrodes, which allows the treatment to be more targeted. This is a good option for patients with sensitive skin, but it also limits the penetration of the energy to half the distance between the electrodes (about 2-8 mm). The biggest advantage of bipolar RF is that it’s less painful than monopolar RF.

Bipolar Radio Frequency can be used for non-invasive fat and cellulite reduction. It stimulates neocollagenesis, and also improves the lymphatic system and blood circulation in the treated area. Moreover, it can tighten the skin by stimulating collagen production. The treatment is comfortable and painless, and results are visible immediately after the first session.

Bipolar RF also promotes the formation of new capillaries in the skin, which further increases the skin’s firmness and elasticity. This treatment can be applied to the abdomen, thighs, arms, and other areas of the body, and is suitable for patients with all types of skin. In addition, it can help to reduce sagging jowls and wrinkles, as well as treat excess fat deposits. The High Tech Combi Slim equipment combines radio frequency and cavitation in one device, which offers a convenient, safe, and effective way to reduce localized fat and cellulite deposits.

Variable frequency

The computer controls the multi-frequency RF signal generator 30 to change its frequency and also adjusts the tunable impedance matching network 34. In one embodiment the RF signals are tuned to Debye resonances of constituents of food for which heating is desired. This is achieved by selecting the appropriate Debye frequency or frequencies and adjusting the RF signal generator’s frequencies or frequency groups to track the changing Debye resonances with temperature. In addition, the RF signal can be tuned to avoid other undesirable resonances.


The purpose of this safety code is to specify maximum levels of human exposure to radiofrequency (RF) fields at frequencies between 3 kHz and 300 GHz, to prevent adverse human health Radio Frequency Handle effects. These exposure limits are imposed in both controlled and uncontrolled environments.

These exposure limits are established on the basis of an ongoing review and evaluation of the scientific literature on thermal and non-thermal human health effects associated with RF radiation. Scientific staff of the Consumer and Clinical Radiation Protection Bureau, Health Canada, perform a rigorous and detailed examination of all peer-reviewed scientific studies that are relevant to the issue of human exposures to low-intensity RF fields. This scientific process utilizes a weight-of-evidence approach that considers the quantity and quality of the research, with emphasis on well-designed and adequately replicated studies with complete dosimetry and appropriate statistics.

Since direct measurements of internal electric fields or SAR are often difficult to perform, reference levels have been specified in this safety code, including external unperturbed electric field strength, magnetic field strength and power density as well as induced and contact currents. These reference levels are based on easily measured or calculated quantities that, when respected, ensure compliance with the underlying basic restrictions. In addition, time periods used for averaging temporally non-uniform exposures are specified in this safety code.
