How to identify home RF beauty equipment

In recent years, beauty equipment has been covering the beauty industry with a scent of embarrassment. Whether it is a large beauty club, a small and medium-sized beauty salon, or a home beauty, it is filled with "appearances of beauty equipment" everywhere. Among them, the "RF" instrument covers the most extensive. As a result, many unscrupulous merchants, using the "RF" signboards, produced so-called "RF beauty equipments" to harm consumers, especially "home RF beauty equipment". Since individual consumers can't discriminate between radio frequency and authenticity with the support of professional knowledge, “home beauty equipment” has become a “radio frequency” paradise for unscrupulous merchants.

In fact, it is not difficult to distinguish between "home RF beauty equipment", as long as the following few points, you can easily see through the "RF" scam. After patience, you will be able to see your eyes and save a lot of money.

What is RF/RF?

Radio frequency/RF is an abbreviation of Radio Frequency, which means electromagnetic frequency that can radiate into space. The frequency range is from 300KHz to 30GHz. Radio Frequency RF is also referred to as RF radio frequency (RF), which is an abbreviation of high-frequency alternating-current changing electromagnetic waves. Alternating currents that change less than 1000 times per second are called low-frequency currents. Alternating currents that change more than 10,000 times per second are called high-frequency currents, and radio frequency is such a high-frequency current.

Definition, Principle and Effect of “RF Beauty” Definition of RF Beauty: Through high-frequency current frequency conversion, it is applied to the surgery department.

The principle of radio frequency beauty: RF beauty positioning tissue can be heated to promote subcutaneous collagen tension, while the skin surface to take cooling measures, the dermis is heated and the epidermis maintains normal temperature.

The effect of RF beauty: RF beauty often produces two kinds of reactions. One is that the dermal layer of the skin becomes thicker, the wrinkles become lighter or even disappear; the second is the remodeling of the subcutaneous collagen, producing new collagen, and the skin will be treated. After becoming more tight.

First of all, to determine the above points, a thorough understanding of the concept of radio frequency and RF beauty, efficacy, in order to better identify the true and false "RF beauty equipment" from the following points.

Differences and Effects of Unipolar RF, Bipolar RF, and Tripolar RF in the Beauty Field I. Unipolar RF In 1996, THERMAGE Inc. pioneered the invention of the ThermaCool RF treatment system, which is a typical unipolar radio frequency, with a frequency of 6MHz at the beginning of the world. After years of clinical practice, the radiofrequency treatment system has been approved by the US FDA to improve the skin in three different ranges, including Qian Zhou (approved in 2002), other parts of the face (approved in 2004), and the whole body (approved in 2005). Wrinkles and relaxation treatment.

After 2002, many institutions in Europe and the United States tried to develop unipolar radio frequency beauty equipment to counter traces of wrinkles and sagging skin. After many years of clinical practice and repeated argumentation, the frequency of 6 MHz (megahertz) has become the optimal frequency for radiofrequency treatment systems.

In 2005, the domestic RF beauty equipment began to test the water market and entered a prosperous period in 2010. Due to limited user capabilities and facilities, it is unable to cope with some highly specialized emergencies. Major manufacturers have set the frequency of home RF beauty equipment to 300-500 KHz (kHz) to protect the user's personal safety. First and foremost. Although 500KHz is lower than 6MHz, the frequency and power are relatively low, but the effect is not much difference. Using 500GHz radio frequency care, the use of 6MHz care can be achieved in one month. Combined with the use of security, it is more suitable for consumers to use at home.

Second, bipolar radio frequency bipolar radio frequency and unipolar radio frequency energy the same principle, the difference lies in the way energy is transmitted. The bipolar radio frequency conventionally designs the positive and negative electrodes to be arranged in parallel or in a concentric ring arrangement, and the current can only be applied between the two electrodes. The distance is extremely short and the penetration depth does not exceed half of the distance between the two electrodes and cannot be applied to the deep layer. organization. Therefore, bipolar radio frequency can not be unique in skin care, and bipolar RF beauty treatment must be combined with monopolar radio frequency or other light source system operation to achieve the desired effect. Therefore, there are few agencies that use bipolar radio frequency as the core technology to develop beauty instruments.

Of course, bipolar radio frequency has its unique properties. Although it cannot compete with unipolar radio frequency in the field of beauty care, bipolar radio frequency in many other fields has made a lot of achievements. We will not go into details here.

Third, three-pole radio frequency Triode radio frequency is a relatively new radio frequency technology, which includes a cathode and a cathode. Theoretically, triode RF combines all the effects of unipolar RF and tripolar RF, and it can also deepen shallow organizations at the same time with the effects of unipolar RF and bipolar RF. Experts predict that in the next few years, tripolar radio frequency is likely to be applied to the treatment of lipolysis.

The application of three-pole radio frequency technology for skin firming and wrinkle removal and fat-soaking and body-sculpting is worth looking forward to. However, the degree of actual operation and the effect of post-surgery treatment based on current technology have not been conclusive. The previous Chinese and foreign literatures have carried out evidence-based medicine. The analysis found that there were no randomized, controlled, and blindly designed research reports on tripolar radiofrequency. Most of them were reported by clinical experience, descriptive research, and expert meetings, and were the third-level evidence with the lowest degree of confidence.

It can be seen that the tri-polar radio frequency needs a lot of R&D and continuous practice to achieve perfect control and service life. We can expect.

Is the "four-pole radio frequency" or even "five-pole radio frequency" technology claimed on the market really fake?

If you patiently read the summary of "unipolar, bipolar, and tripolar radio frequency" above, you can see that this is a gimmick for unscrupulous merchants to attract consumers.

Today, tri-polar radio frequency is still in the R&D practice stage. If a domestic or foreign organization or company successfully develops a “four-pole radio frequency” or “five-pole radio frequency” and successfully puts it into the market, it will be a huge investment, relying solely on “patents”. Can make extraordinary profits, earn pours, all major media will have to report, and may even win the Nobel Prize in physics.

How to identify the true and false effects of "Shooting Home Frequency Beauty Instrument" that can both face care and body care?

With regard to distinguishing “home radio frequency beauty instruments” that can both care for the face and can care for the body, we can easily distinguish between the above concepts. as follows:

First of all, radio frequency technology for beauty care is currently divided into three kinds of monopolar, bipolar, and tripolar radio frequencies. Tripolar radio frequency is still in the research and development phase, bipolar radio frequency independent care effect is not ideal, must be combined with unipolar radio frequency or other Light source for therapeutic care. It can be seen that unipolar radio frequency is currently the most perfect technology in the beauty care field. The so-called "four-pole radio frequency" and "five-pole radio frequency" are, in the present situation, nonsense;

Secondly, as consumers, individual capabilities and professional knowledge cannot be compared with large-scale medical institutions or beauty clubs. For the purpose of protecting consumers' personal safety, major production families set the frequency of “family RF beauty equipment” as a standard. Set at 300 to 500 KHz (kHz), rather than the 6 MHz (megahertz) frequency of a professional monopolar radiofrequency treatment system. Keep using the same effect. Therefore, to identify "home RF beauty equipment", you can see the frequency of the product set, if more than 500KHz, it is likely that small producers make gimmicks, consumers are not responsible for the production of "fake and inferior products" <Note: 1MHz (megahertz) = 1000KHz (kHz)>;

In addition, there is a distinction between "being able to care for the face while being able to care for the body". The frequency of a radio frequency determines its frequency range (also called wavelength). The lower the radio frequency, the longer the wavelength. Conversely, the higher the frequency, the shorter the wavelength. However, when the RF frequency is lower than 300KHz (kilohertz), the dermis cannot be heated by energy conversion, and the regeneration of subcutaneous collagen can not be stimulated; if the RF frequency exceeds 6MHz (the standard frequency of the professional RF treatment system), the wavelength will be too short. Can not be applied to the dermis layer; and home RF beauty instrument frequency exceeds 500KHz, it is prone to accidents.

Because the thickness of the skin on the face and body is not the same, the care of the face requires a radiofrequency care with a relatively high frequency and a short wavelength, and the care of the body requires a radiofrequency care with a relatively low frequency and a relatively long wavelength (the frequency can be adjusted from 300KHz to 500KHz). Therefore, if the same RF beauty instrument can both care for the face and the body, then it must use other media that can adjust the frequency to meet the conditions of a radio frequency beauty instrument for facial and body care. This type of media is usually produced in a convenient shape such as a waistband.
