What is RF(Radio Frequency) ?
Radio Frequency surgery has a lengthy history of use in oral, ophthalmic, plastic, and gynecological surgery of over 70 years. Its use in the practice of cosmetology and dermatology to treat wrinkles and skin laxity is from 1990's.
Radio Frequency (RF) is a method of physical therapy that involves generating local heat in body tissues by high-frequency electrical current. The thermal effect of the RF energy depends on the electrical properties of the tissue. As the current streams through the tissue and ions rapidly change polarity back and forth, heat is generated by the tissue's natural resistance to the flow of current within an electric field.
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.
Unipoplar delivery: the current release from the generation machine, without any grounding or return pad.
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 developed RF 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 21 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.
Theory of Monopolar RF Machine
Monopolar RF takes that epidermis balances normal temperature, RF electric wave produces heat into deep skin as nuclear technique, based on assurement of skin comfortable, harmless, it uses RF electric wave to produce heat exchange, precisely attains skin deep, stimulates inner ion of body, colloid granule with electricity will be forced rapid movement, vibration or attrition, then produce heat energy. At same time, under effect of polarized molecule resonance, it heats collagen tissue of dermis layer. When deep collagen tissue is heated up to 45℃-60℃, it will naturally produce instant shrinking, stimulate to excrete much new collagen to make up interspace of the shrinking or lost collagen protein, and make them rearray, rebuilt skin soft bracket, finally get tight skin, remove wrinkle, recover skin elasticity and luster.
Features of Monopolar RF Machine
1. Rolling Electrode Type and oriented Pad Type available, aim at diffierent treating requirements.
2. Electronic digital control system: Adjust frequency and time, very simple and convenient.
3. Special design on RF heads: It equipps with different sizes of RF heads, suitable for face skin or body different parts.
4. Safety switch: it controls emergency pause to prevent overeating and inducint accidents.
5. Start form ‘Zero’: To prevent any possible accidents.
6. Inner Time Control: Treated time between 5 to 60 minutes, safe and free.

Radiofrequency
What is Radiofrequency (RF)?
Radio Frequency (RF) treatment uses electrical pulses to effectively tighten skin and reduce wrinkles. It works by selectively delivering heat energy to the middle and lower levels of skin stimulating new collagen growth.
What can radiofrequency (RF) energy do?
- Facial Tightening. Eliminates fine lines and wrinkles and sagging eyelids/chins.
- Body Tightening. Eliminates stretch marks and sagging skin.
- Collagen Reformation and facial rejuvenation.
- Body contouring and circumferential reduction.
- Slimming.
- Reduction of cellulite.
Who should not undergo this procedure?
As long as you are generally healthy and don’t have any skin diseases or infections in the area treated, there are few medical reasons why patients should not undergo this treatment.
People with sensory disturbance to the skin may not be considered good candidates as this could make the reporting of discomfort during the procedure unreliable, leading to overheating and potential harm.
Although there is no evidence that this treatment is harmful for pregnant women, you would generally be advised to wait until after you have given birth before embarking upon a course of treatment.
More importantly, people with electrical devices e.g., pacemakers, or metal implants e.g., artificial metal hip joints, heart valves or dental plates, cannot be treated because RF energy flowing through the body may interfere with these devices or heat up metal implants, which could be dangerous.
Are there any precautions you should take before the procedure?
You should try to avoid doing anything that will irritate your skin immediately before treatments. (suntanning, scrubbing) All metallic accessories such as chains, earrings and watch should be removed from the body before starting RF.
How is the procedure done?
- The treatment area is thoroughly cleansed to remove excess oils and impurities.
- If required, a numbing cream can be applied prior to the procedure and allowed to set in for 30 mins.
- A treatment grid ink transfer may be applied over the treatment area to assist our doctor or therapists in navigating the area whilst delivering the RF energy. This helps to assure an even application of the RF energy and to prevent inadvertent overlapping of treatment.
- A coupling gel may then also be applied over the treatment area which acts as an additional barrier between the surface layers of your skin and the handpiece of the device.
- Our doctor or therapist will then commence the RF treatment working across the treatment area.
- Once completed a soothing gel or lotion will be applied to your skin.
Is the procedure painful? How does the procedure feel like?
Treatments are painless. As the treatment is carried out you will experience brief, deep heating sensations every time the RF energy is delivered to your skin and underlying tissue. At Clariancy Aesthetic Clinic, our RF device have a cooling system to protect your skin from overheating, and thus making treatments very comfortable.
What are the precautions you should take after treatments?
No special care is required after treatments. Application of soothing/moisturising ,cool water rinses or ice packs can be applied to the treatment areas to ease skin irritation if required.
What is the downtime after RF treatments?
There is no downtime. You can return to work immediately after treatments.
When will I see results?
Your skin will feel tighter immediately after the first session. You may require multiple sessions to achieve the overall desired effects. More skin tightening improvements will appear gradually over the next few months even after treatments. Our doctor will be able to determine a course of treatments specific to you and your needs. Results are said to last up to a couple of years but we advise regular maintenance treatments to enhance the overall effects.
What are the potential complications from RF treatments?
In the majority of cases, they are no complications from RF treatments. On occasions, swelling, redness, bumps and blisters may appear on or around the treated area. They typically disappear in a few days to a week. Very rarely, RF treatments may give rise to depressions in the skin. This is attributed to the overheating of underlying tissue causing fat atrophy or excessive tightening, giving you a sunken appearance in the affected area. At Clariancy Aesthetic Clinic, our doctor and therapists are professionally trained and such complications are virtually non-existent.
