1. What is radio frequency?

Radio frequency, abbreviated as RF, is radio frequency current, which is the abbreviation of a high-frequency alternating electromagnetic wave. Alternating current that changes less than 1000 times per second is called low-frequency current, and alternating current that changes more than 10,000 times per second is called high-frequency current, that is, radio frequency current.

In electronic theory, when current flows through a conductor, a magnetic field is formed around the conductor; when alternating current passes through a conductor, an alternating electromagnetic field is formed around the conductor, which is called an electromagnetic wave.

Radio, microwaves and even hotel door cards are electromagnetic radiation energies, which are collectively referred to as radio frequency; the frequency range is very wide, ranging from hundreds of kHz to hundreds of MHz. RF cuts, resects, electrocauterizes, ablates and coagulates tissues through electrothermal action, thereby achieving the purpose of removing lesions and treating diseases.

2. What are the classifications of radio frequency?

Radiofrequency (RF) is a high-frequency alternating electromagnetic wave between amplitude modulation and frequency modulation radio waves. Its energy exists and propagates in space in the form of electricity or magnetism (waves). The frequency range is 100 kHz to 30 GHz, and it is divided into monopolar, bipolar and multipolar radio frequency.

2.1 Monopolar RF.

It consists of an activation electrode and/or a loop electrode. The depth of current conduction depends on the size of the treatment head and can reach 2 to 4 mm deep into the reticular dermis and subcutaneous layer. Thermage, which is currently popular on the market, is a type of monopolar RF.

2.2 Bipolar RF.

It consists of two symmetrical positive and negative electrodes. The penetration depth is about half the distance between the two electrodes, so the penetration depth is shallow (less pain during treatment). Therefore, in order to ensure deeper treatment, it is often combined with other technologies (in simple terms, the efficacy is not as good as monopolar RF).

2.3 Multipolar RF.

It is composed of 3 or more electrodes, all of which alternately exchange positive and negative charges to form a current loop between any two electrodes. Multiple current loops can concentrate the treatment energy, prevent overheating in the epidermis, and maintain high-density current in the treatment area without additional cooling. The conduction depth can reach the subcutaneous layer.

3. Principle of monopolar radiofrequency skin beauty.

The mechanism of action of radio frequency is to use the conversion of electric field polarity to produce a thermal effect on the friction of tissues through which the current passes (i.e., converting electrical energy into thermal energy). Since the dermis has the highest conductivity in the skin tissue, the current is mainly concentrated in the dermis, causing large-scale capacity heating of the dermis tissue, making the dermis heated to 45-60°C. The heat energy acts on the collagen tissue, causing thermal denaturation, causing the collagen fibers to contract, fuse and reshape, making the dermis thicker, the skin firm and elastic, and thus achieving the effect of skin rejuvenation.

Monopolar radio frequency technology transmits high-frequency current to the deep layers of the skin, produces a thermal effect, promotes the contraction and regeneration of collagen, and thus achieves the effect of tightening the skin. This thermal effect can not only tighten collagen fibers instantly, but also stimulate the regeneration of collagen in the deep layers of the skin, which can last for months or even years.

Monopolar radiofrequency can selectively transfer heat energy to the dermis and subcutaneous tissue. Short-term primary collagen contraction occurs immediately after treatment. Then reversible thermal damage activates the skin repair mechanism, upregulates the expression of type I collagen mRNA, causes new collagen fiber synthesis, and leads to collagen remodeling. This process occurs 2 to 6 months after RF treatment and lasts for a long time.

In addition, tissue thermal damage can activate the body’s wound healing response, stimulate fibroblasts, and promote new collagen formation. Collagen proliferation can make skin wrinkles shallower and the surface smoother and more elastic by increasing volume.

Radiofrequency has been used in the field of anti-aging for a long time. In 2002, the US Food and Drug Administration first approved RF equipment for skin wrinkle removal, and used it for clinical facial wrinkle removal in 2004. It is mostly suitable for mild to moderate facial wrinkles and was publicly approved for use in 2006.

4. What are the advantages of monopolar radiofrequency machines?

Compared with traditional surgical facelifts, monopolar radiofrequency technology has the significant advantages of being non-invasive, painless, and having a short recovery period. Its non-invasive characteristics mean that patients do not need to worry about surgical risks and postoperative recovery, and can do it as they please, which is very suitable for patients in modern fast-paced life.

4.1 It has a comprehensive effect, and can improve the eyes, face, and body.

Monopolar radiofrequency machines can not only act on the face, but also have special treatment heads for eye and body anti-aging.

Facial anti-aging: Improve skin firmness, improve facial wrinkles, sagging apple muscles, and double chins caused by loose skin.

Eye anti-aging: It can tighten loose skin around the eyes, and is the only project that has passed dual certification of the US FDA and China NMPA for eyelid wrinkle removal.

Whole body anti-aging: It can be used for waist and abdomen shaping, buttocks shaping, leg shaping, and butterfly sleeve treatment, especially suitable for loose skin and stretch marks after childbirth.

4.2 Non-invasive operation, short recovery period.

Monopolar RF is a non-invasive operation. You can leave immediately after the treatment, and the recovery period is short. Some people may experience edema, which usually disappears in 2 to 3 days.

4.3 Do it once every 1 to 2 years, the light of lazy medical beauty.

The anti-aging effect of monopolar radio frequency machine has two major characteristics: one is the immediate reaction, and there will be a visual tightening effect at the moment of completion. The other, and more important, is the long-term increase in collagen.

After the anti-aging treatment, collagen will gradually regenerate, and the state effect usually reaches the “peak” in 3 to 6 months.

Therefore, monopolar RF has better durability, and it can usually be done once every 1 to 2 years (depending on age and aging).

After stopping the anti-aging project, there is no need to worry too much about rebound. The skin will not age faster, but just return to the normal state and speed of aging.

5. Clinical trial verification: the magical effect of monopolar radiofrequency.

5.1 Clinical trial of the latest generation of monopolar radiofrequency devices.

In the article “Prospective clinical trial of the latest generation of non-invasive monopolar radiofrequency treatment for facial and upper neck skin laxity”, researchers selected 40 subjects between 30 and 60 years old and used the latest generation of monopolar radiofrequency devices for facial and upper neck skin laxity treatment. The results showed that 73% of the subjects had significantly improved skin laxity in the chin and nasolabial folds 6 months after treatment. The satisfaction of the subjects was also very high, and more than 80% of the subjects were satisfied with the treatment effect.

5.2 Clinical verification in Asian populations.

In the article “Effectiveness and safety of monopolar radiofrequency treatment for lower facial laxity in Asians”, researchers performed monopolar radiofrequency treatment on 30 Asian subjects. The results showed that within 6 months after treatment, most subjects had significant improvement in skin laxity and no serious adverse events. The average pain score of the subjects during the treatment was only 3.13 (out of 10 points), which proved the safety and effectiveness of monopolar radiofrequency in Asian populations.

6. Comprehensive evaluation of monopolar radiofrequency technology.

6.1 Comparison of monopolar radiofrequency and bipolar radiofrequency.

In the article “Systematic Review of Minimally Invasive Face and Body Skin Tightening Methods”, researchers conducted a comprehensive evaluation of monopolar radiofrequency and bipolar radiofrequency technology. The results showed that monopolar radiofrequency has significant advantages in improving skin laxity, smoothness, brightness, moisturizing and reducing subcutaneous fat. However, compared with bipolar radiofrequency, the complication rate of monopolar radiofrequency is relatively high, so special attention should be paid to the operation specifications during the treatment.

6.2 Clinical application and prospects of monopolar radiofrequency.

Due to its excellent effect and safety, monopolar radiofrequency technology has become one of the “gold standards” for skin tightening treatment. With the continuous advancement of science and technology, the technology of monopolar radiofrequency equipment is also constantly upgrading. In the future, there will be more innovations and breakthroughs to further improve the treatment effect and safety.

7. Actual experience of monopolar radiofrequency treatment.

7.1 Detailed explanation of the treatment process.

The monopolar radiofrequency treatment process is simple and convenient. First, the doctor will apply coupling gel to the treated area to ensure that the radiofrequency energy is evenly transmitted. Then, the doctor uses the monopolar radiofrequency device to scan the skin surface several times. The whole process takes about 30 to 60 minutes. After the treatment, the treated area may have slight redness and burning sensation, but it usually subsides on its own within a few hours.

7.2 Post-treatment care suggestions.

For the best results, you need to pay attention to the following points after treatment: Avoid direct sunlight and apply sunscreen when going out. Keep your skin clean and avoid using irritating skin care products. Avoid high temperature environments such as saunas, steam baths, etc.

8. Indications and contraindications of monopolar radiofrequency equipment treatment.

Indications: Monopolar radiofrequency is suitable for the following conditions: sagging skin on the face and neck; fine lines and wrinkles; large pores; uneven skin tone.

Contraindications: The following conditions are not suitable for monopolar radiofrequency treatment: skin infection or inflammation; pregnancy or breastfeeding; wearing electronic devices such as pacemakers; allergies to radiofrequency equipment.

9. Factors affecting the efficacy of monopolar radiofrequency and operational details.

9.1 The relationship between monopolar radiofrequency and epidermal temperature.

The epidermal temperature of the monopolar radiofrequency machine target is 40~42℃. The temperature gun can be used to assist in understanding the temperature of the epidermis during treatment. At the same time, at this temperature, the junction of the dermis and the subcutaneous layer can be roughly estimated to have a temperature difference of 20℃, which means that there will be about 65℃ of heating energy in the dermis. If the patient scores 7~8 points, it feels a little hot, but it is tolerable.

If the epidermal temperature is lower than 40℃, the treatment effect will be affected. If it reaches 45~47℃, most patients will naturally bounce back, unable to tolerate the treatment and have the risk of burns. Higher temperatures will cause irreversible side effects such as scar hyperplasia. Therefore, maintaining the skin temperature at 38~42℃ is the ideal temperature for maintaining collagen contraction.

9.2 Treatment of electrical impedance and conductivity.

The electrical impedance of the skin tissues at different levels is not the same. The stratum corneum has low water content and poor conductivity, while the dermis has high water content and strong conductivity, so the reticular layer will be heated first when heating.

At the same time, compared with wet skin, dry skin has higher resistance, so the skin conductivity can be increased by increasing the hydration of the skin, such as mesotherapy, or water replenishment, and then radiofrequency treatment can be performed.

9.3 Personalized operation skills.

The first is the facial lifting technique, which everyone may be very familiar with. The full face follows the super pass method to evenly heat the entire face to stimulate the regeneration of collagen. When we are doing vector line lifting, we must remember these lifting lines:

The first lifting line starts from the side of the nose, from the bottom of the apple muscle to the area in front of the ear, the highest point in front of the ear.

The second vector line is from the bottom of the mouth to the front of the ear.

The third vector line is operated along the mandibular margin.

The fourth is below the mandibular margin.

At the same time, when doing the frame periorbital, in addition to flat laying, there are two vector lines above the eyebrows, so everyone should pay attention to the facial periorbital lifting technique during the operation.

9.4 Overall operation plan optimization design.

Then how to achieve the best single-time efficacy in clinical practice, how to be more comfortable, and how to minimize adverse reactions are all combined with the entire process of operation.

First of all, pay attention to the preoperative evaluation. The monopolar radiofrequency machine is suitable for patients with mild to moderate skin sagging. During the evaluation, key areas are marked at the same time, such as the starting and ending points of the ligaments and the location of fat bulging. At the same time, you can determine what kind of lifting line to do by pulling its anchor point, and focus on strengthening the lifting line including the eye.

At the same time, you can also cooperate to avoid some sunken areas. For example, if the patient has severe cheek concavity, you can draw a cross line within this area to remind yourself to avoid this place and do it below and around it. In the later stage, you can target the cheek concavity and the location of the concavity, and do some water light after surgery to make a connection.

Therefore, it is necessary to mark the lifting line, as well as the position that needs to be strengthened, the position where there is local fat accumulation, and the position of the depression. The patient should be informed that the depression will be avoided during the operation, and only the upper and lower parts will be touched to improve its connection. In this way, the patient’s satisfaction will naturally increase during the entire evaluation process, and the recognition of the doctor will be strengthened from the details.

In addition to the mild to moderate relaxation of facial and neck fat, it is also necessary to focus on the relaxation and sagging of the eyes, tighten the skin around the eyes, reduce fine lines, and make the eyes bigger and more energetic. At the same time, for people who are pregnant or have lost weight, the body treatment head can be used for shaping and tightening, truly realizing multi-part anti-aging and playing an overall rejuvenation role.

Facial treatment first follows the super pass method, x-axis flat, full face application 2~3 times, for vector line y-axis lifting, application 4~5 times, and for the eyes, it is generally recommended not to overlap it. This is a standard allocation. At the same time, when designing the standard allocation, the super pass method follows the principle of first square and then circle, 50% overlapping coverage, from inside to outside, and from top to bottom.

Finally, there are some small details of the operation. First, the doctor should have a very comfortable posture. During the operation, the patient should turn the whole face over so that each heated surface is perpendicular to the direction of the customer’s skin.

Second, the hand has appropriate pressure. Of course, the system will also actively prompt excessive pressure, excessive skin temperature, etc. to ensure the most appropriate strength.

Third, give the skin enough cooling time and pay attention to the application of coupling fluid. About one facial treatment head corresponds to one bottle of coupling fluid.

Finally, the endpoint reaction reflects the firmness and lifting touched. You will see that the skin elasticity increases, and the glossiness is improved at the same time.

10. Best monopolar radiofrequency machine – SUPERMAGIC.

10.1 Monopolar RF 6.78 MHz beauty machine.

SUPERMAGIC is a high-quality anti-aging beauty machine launched by Huafei Liton Laser more than 10 years ago. It is a monopolar non-invasive radiofrequency skin treatment device with a frequency of 6.78 MHz. It uses the best anti-aging frequency of Thermage in the United States. It is a top anti-aging device that can achieve significant lifting, firming and wrinkle removal effects in one treatment.

Supermagic has made a number of technical upgrades to the skin and aging characteristics of oriental women while ensuring the anti-aging effect, making it more suitable for oriental women. It has FDA and CE certificates.

10.2 The working principle of Supermagic.

Human tissues naturally resist the movement of electrons in the radio frequency electric field. The transmission of radio frequency waves is not affected by epidermal pigments, which causes the skin dermis to produce a thermal effect, fully heating the dermis, causing the epidermal temperature to reach about 42°C.

The thermal stimulation of radio frequency can cause elastic fibers and collagen fibers to shrink immediately, resulting in a sense of firmness; thermal stimulation activates the skin repair and healing mechanism, stimulating the regeneration and remodeling of new collagen fibers. As the number of new collagen fibers increases and the arrangement becomes tighter, the loose and aging state of the skin is further repaired.

10.3 Supermagic effect cycle.

10.4 Supermagic core advantages.

10.4.1 Safe and intelligent.

No need for anesthetics, no safety issues such as anesthetic allergy and delayed reaction due to nerve conduction block; over-temperature protection technology: when the epidermal control temperature reaches the preset temperature, the energy input will be automatically blocked, so it is a double insurance for customer safety. At the same time, as long as the epidermal temperature is kept at around 42℃ for about 3-5 minutes, the subcutaneous temperature can reach 55℃~65℃, which is also the temperature that must be reached for collagen regeneration. It is safe and effective, and completely avoids all kinds of risks caused by relying solely on doctor’s experience.

10.4.2 High comfort.

The multi-mode selection of the equipment, combined with the diversity of treatment techniques, can be fixed, slidable, and circled, making customers feel more comfortable, there is no blind spot in facial treatment, the treatment process is more scientific and safer, and can meet the needs of various pain tolerance groups.

10.4.3 More precise treatment.

There is no blind spot in facial treatment, and it can be used around the nose and mouth. It can fully liberate the doctor’s techniques and achieve local precision treatment in combination with the doctor’s face-to-face consultation; especially in eye treatment, it has a unique advantage (no blind spots in the upper eyelid, lower eyelid, orbital and extraorbital), which completely exceeds traditional photoelectric equipment.

10.4.4 One machine is more convenient.

With its own comfortable treatment gene, the treatment process is very comfortable, without the need for additional hydration and other radio frequency assistance.

10.5 Supermagic function.
