Teach you to identify true and false "household radio frequency beauty equipment"-Beijing Zhenhuimei Beauty Equipment Co., Ltd.

In recent years, beauty equipment has covered the beauty industry with a prairie fire. Even large beauty fairs, small and medium beauty salons, and home beauty are full of "machine beauty". Among them, radio frequency" equipment has the widest coverage. Therefore, many unscrupulous merchants manufacture so-called "radio frequency beauty instruments" under the signboard of "radio frequency", causing harm to consumers, especially "home radio frequency beauty instruments". Since individual consumers cannot distinguish true and false radio frequency with the support of professional knowledge, home beauty instrument" has become a "radio frequency" paradise for unscrupulous merchants.

In fact, it is not difficult to distinguish "home radio frequency beauty equipment". As long as you master the following points, you can easily see through the "radio frequency" scam. After reading it patiently, you will be able to see clearly and save a lot of wasted money.

What is Radio Frequency/RF?

Radio frequency/RF is the abbreviation of Radio Frequency, which means the electromagnetic induction frequency that can radiate into the indoor space, and the frequency range is from 400KHz to 40GHz. Radio Frequency is also commonly known as RF, that is, radio frequency, which is the abbreviation of high-frequency alternating electromagnetic waves. The alternating current that changes less than 1,000 times per second is called low-frequency current, and the alternating current that changes more than 10,000 times per second is called high-frequency current, and radio frequency is such a high-frequency current.

Definition, principle and effect of "radiofrequency cosmetology"

The definition of radio frequency cosmetology: through the frequency conversion of high-frequency current, its effect is applied to the surgical department.

Principle of radio frequency cosmetology: radio frequency cosmetology can accurately locate and locate tissue heating to promote the contraction and tension of subcutaneous collagen, and at the same time take cooling measures on the surface of the skin, and heat the dermis to keep the epidermis at a normal temperature.

The effect of radio frequency cosmetology: There are usually two reactions to radio frequency cosmetology. One is the thickening of the dermis of the skin, and the wrinkles become lighter or even disappear. Second, subcutaneous collagen is remodeled to produce new collagen, and the skin becomes firmer after treatment.

First of all, we must determine the above points, thoroughly understand the concept and effect of radio frequency and radio frequency beauty, in order to better distinguish between true and false "radio frequency beauty instrument" from the following points.

Differences and effects of monopolar radiofrequency, bipolar radiofrequency and tripolar radiofrequency in the field of cosmetology

Unipolar RF

In 1996, ThermaCool radio frequency treatment system was first invented by THERMAGE Corporation of the United States, which is a typical monopolar radio frequency. Its initial frequency is6MHz. After years of clinical practice, the radiofrequency treatment system has been approved by the US FDA to improve the periorbital (approved in 2001), other parts of the face (approved in 2004) and the whole body (approved in 2008) in three different areas. Treatment of inner skin wrinkles and sagging.

After 2002, many institutions in Europe and the United States tried to develop monopolar radio frequency beauty equipment to fight against aging signs such as wrinkles and skin sagging. After years of clinical practice and repeated demonstrations, the frequency of 6MHz (megahertz) has become the best frequency for radio frequency treatment systems.

In 2005, household radio frequency beauty equipment began to test the water market, and in 2010 it entered a prosperous period. Due to the limited ability and facilities of users, it is impossible to deal with some highly professional emergencies. Major manufacturers have set the frequency of household RF beauty equipment at 300-500KHz (kHz) to ensure the personal safety of users. first of all. Although 500KHz is relatively lower in frequency and power than 6MHz, the effect is not much different. Using 500GHz radio frequency nursing can achieve the nursing effect of using 6MHz after one month. Combined with the safety of use, it is more suitable for consumers to use at home.

Bipolar RF

The basic principle of the kinetic energy effect of bipolar radiofrequency and monopolar radiofrequency is the same, and the difference depends on the method of kinetic energy introduction. Bipolar radio frequency basically designs the positive and negative electrodes as a parallel arrangement or a circular arrangement in the same boat, and the current can only act between the two electrodes, the distance is extremely short, and the penetration depth 1 does not exceed one of the distances between the two electrodes. For the most part, deep tissue will not be affected. Therefore, bipolar radiofrequency cannot be unique in skin care, and bipolar radiofrequency cosmetic treatment needs to be used in combination with monopolar radiofrequency or other light source systems to achieve the desired effect. Therefore, few organizations have developed beauty instruments with bipolar radio frequency as the core technology.

Of course, bipolar RF has its own unique characteristics. Although bipolar radiofrequency cannot compete with monopolar radiofrequency in the field of beauty care, bipolar radiofrequency has made many achievements in other fields, so I won't repeat them here.

Three-pole RF

Tripolar RF is a relatively new RF technology that includes one positive and two negative electrodes. In theory, tripolar radiofrequency combines all the effects of monopolar radiofrequency and tripolar radiofrequency, and can add deep and shallow tissues to the effects of monopolar radiofrequency and bipolar radiofrequency, with remarkable results. Experts predict that in the next few years, tripolar radiofrequency may be applied to the treatment of lipolysis and body shaping.

The application of three-pole radio frequency technology in skin tightening, wrinkle removal, fat dissolving and body shaping is worth looking forward to, but the current technology has no clear conclusions on the actual operation degree and postoperative effect. Evidence medical analysis. It was found that the three-pole radio frequency has not been followedMost of the research reports of randomized, controlled and blinded designs are clinical experience, descriptive research and expert meeting reports, which are the third-level evidence with the lowest reliability.

How to distinguish the authenticity and efficacy of the "household frequency beauty instrument" that can be used for both beauty and body care?

Regarding the difference between "home radio frequency beauty equipment" that can care for both the face and the body, we can easily distinguish it by combining the above concepts. As follows:

First of all, there are currently three types of radiofrequency technologies used in cosmetic surgery, namely monopolar, bipolar and tripolar radiofrequency. Tripolar radiofrequency is still in the research and development stage, and the effect of bipolar radiofrequency independent care is not ideal. Monopolar RF or other light sources must be used in conjunction with therapy and care. It can be seen that monopolar radio frequency is currently the most perfect technology in the field of beauty care. The current so-called "four-pole radio frequency" and "one-fifth radio frequency" are nonsense.

Secondly, as an individual consumer, his personal ability and professional knowledge cannot be compared with large medical institutions and beauty clubs. In order to protect the personal safety of consumers, major manufacturers have agreed to set the frequency of "home radio frequency beauty instrument" to 300 ~500 khz (kilohertz), not the 6MHz (megahertz) frequency of professional monopolar RF therapy systems. Stick with the same effect. Therefore, to distinguish "home radio frequency beauty instrument", you can check the frequency of product settings. If it exceeds 500 kHz, it is likely to be a "fake product" made by a small beauty equipment manufacturer. They make gimmicks and are extremely irresponsible to consumers.

Furthermore, about the discrimination of "can take care of both the face and the body". The frequency of 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 radio frequency is lower than 300KHz (kilohertz), the dermis cannot be heated by energy conversion, let alone stimulate the regeneration of subcutaneous collagen; if the radio frequency exceeds 6MHz (the standard frequency of professional radio frequency treatment systems), the wavelength will be too short. It can't act on the dermis; and the frequency of the home radio frequency beauty instrument exceeds 500KHz, it is easy to cause accidents.

Because the thickness of the skin of the face and the human body is different, the treatment of the face requires radio frequency treatment with a higher frequency and shorter wavelength of light, while the treatment of the human body requires radiofrequency treatment with a lower frequency and a longer wavelength of light (the adjustable frequency range is between 400KHz and 600KHz) . At the same time, if the same radio frequency beauty device can care for the face and body at the same time, it must meet the conditions for the radio frequency beauty device to care for the face and body through other frequency-tunable media. Such media are often manufactured in a form that is as easy to use as a belt.
