Most beauty equipment is effective, but it must be based on "persistent use". When choosing a beauty instrument, you must give priority to internationally renowned big-name products. Don't buy inexplicable knockoffs, because many technologies are double-edged swords. If you do not master the core data and degree, it is easy to produce side effects. Become an artifact of ruining faces.

Although we can refuse to be destroyed and refuse to enter the pit, the pig-killing knife of the years will not let us go. Therefore, I think it is very necessary to choose one or two cost-effective beauty instruments as tools for daily combating gravity.

Beauty equipment has three characteristics: high price, fast update, and difficult to persist! Are these thousands of home RF beauty devices really useful? Will it hurt the face? Will long-term use cause premature skin aging?

First of all, I must say something. I am using it myself, and I also find it "useful". But this "usefulness" itself is based on subjective and objective perspectives. Objectively, you have to understand the principle of the beauty instrument to analyze whether it has achieved the claimed principle; subjectively, you have to use it correctly, stick to it, and a very important point: have a reasonable expectation of the beauty instrument.

What is RF beauty?

Radio frequency refers to electromagnetic waves within a certain frequency range (frequency 300KHz ~ 300GHz), the English abbreviation RF (redio Frequency), the English full name is translated into radio waves.

If the various electromagnetic waves that we are more familiar with in life are sorted by frequency, from low frequency to high frequency, they are high-voltage lines, radio waves (signals from radios, televisions, mobile phones, etc.), microwaves, infrared rays, visible light, ultraviolet rays, X-rays ( It means taking X-rays, the kind of rays used in subway security inspection fluoroscopes), gamma rays (the rays of the gamma knife used in medical treatment), among which the frequency range of radio waves and microwaves belongs to radio frequency.

How RF works

RF energy can heat tissues quickly (just like what happens when cooking food in a microwave oven). After reaching a certain temperature, the collagen fibers in the heated part will shrink. This is why we see the instant tightening. If the temperature is higher, the collagen in the heated part will coagulate. This is a kind of damage. This damage can stimulate the skin's self-repair mechanism, stimulate the regeneration of collagen, and achieve the purpose of longer-lasting skin tightening.

In theory, you just put a hot water bottle on your face, as long as you can heat the dermis to a certain level, you can have the same firming effect!

However, the heat of the hot water bottle is mainly released on the epidermis. If the temperature is too high, the epidermis can't stand it. If the temperature is too low, the dermis will not heat and it will not be effective, while the hot Maggie heats the inside and outside together.

There are several types of medical radio frequency, such as hot maji, red radio wave, hot lift, and dark blue radio frequency. The difference from household equipment is energy and depth of action.
