Description

What is radiofrequency?
Technically speaking, radiofrequency is the number of oscillations (or waves) per second of the electric and magnetic fields within the radio waves portion of the electromagnetic spectrum.
It is lowest of the electromagnetic radiation frequencies within the spectrum, which itself spans from radio waves, microwaves, infrared, optical (visible light), ultraviolet, x-rays, to gamma rays.
By feeding an alternating current (AC) or voltage through an antenna or electrode, electromagnetic waves can be generated that radiate through space at the speed of light; called radio waves. Radiofrequencies, or radio waves, have wavelengths ranging from less than a centimetre to as long as **0 kilometres.

UK domestic electricity which itself is an alternating current could in theory be used for “electrosurgery”, however as most people know, contact with this kind of electric current can cause very undesirable effects such as electrocution and uncontrolled neuromuscular (nerve and muscle) stimulation. However, if the frequency of the alternating current is raised above the response time of neuromuscular structures, we find the radiofrequency range which can safely be used for medical/surgical applications.
By applying RF energy to the human body, which can conduct current and therefore act as part of the electrical circuit, any resistance encountered by the energy flow will cause heat to be produced at the site of maximum resistance, which can be used to cut or coagulate tissue.
When comparing non-ablative (procedures that do not involve the destruction of the outer layer of the skin) techniques, RF energy differs from laser (light) energy in that light energy tends to scatter or absorb into the upper layers of the skin, making it difficult to deliver sufficient heat into the deeper layers without damaging the skin's surface. Lasers therefore affect collagen in the upper dermis, improving fine lines, wrinkles and skin texture, while RF energy is able to penetrate deeper into the skin and affect the deeper dermis and subcutaneous layers, causing tightening and improvements to the underlying tissue structure, but with little change in skin texture or fine lines and wrinkling.

Types of radiofrequency delivery

Monopolar (also called Unipolar)
Monopolar or unipolar refers to a device having one pole or electrode.
With monopolar delivery, the current from the generating machine flows through the body from a single electrode (handpiece) and meets maximum resistance in the area around the tip of the handpiece, where tissue heating in the subdermal layers then occurs. A grounding, or “return pad” may also be used, attached to the patient’s lower back or abdomen, to provide a low resistance path for the current to flow back to the generating machine, to complete the electrical circuit.

Biopolar
Biopolar refers to a device having two poles or electrodes.
With bipolar delivery, the current from the generating machine flows only through the tissue which is between the two electrodes on the handpiece; these electrodes start and complete the electrical circuit. Hence, with bipolar delivery, no current flows through the rest of the body, so no grounding or return pad is needed.
In all cases of radiofrequency delivery types, it is the resistance to the current flow in the tissue, not the electrode that generates the heating effect.

Summarize

Aiming at civilization development, medically it is researched and developedRF System, which integrates facial and body slimming, without any side effect. As the modern high-tech equipment, RF Machine is widerly used in beauty and slimming salons etc.

Monopolar RF Machine is the newest wireless skin lifting and body slimming in *1 century. Different with operation, people use it on beauty or slimming salons, most effectively and safest.Monopolar RF Machine has double-frequency system, which is a newly concept integrated with high-tech fruition as multi-functional double-frequency beauty RF system and slimming machine. It eradiates high-effective heat energy, activate collagen tissue, enters deep skin layers, to rapidly attain purpose of beautifying face and body.
