The alternating current that changes less than 1,000 times per second is called low-frequency current, and the one that is greater than 10,000 times is called high-frequency current, and radio frequency refers to this high-frequency current. Medical frequency in 0.5 ~ 8MHz AC high-frequency current is called radiofrequency waves. Since 1868 Da rsonval first radiofrequency technology applied to living tissue, radiofrequency technology has been gradually applied to neurology, cardiology, liver tumors and other clinical areas, until 1996, the United States of America THERMAGE company ManjT, Abraham invented ThermaCool technology, and in 2002 was approved by the FDA, radiofrequency technology began to be used in the field of skin aesthetics, a large number of literature reports that radiofrequency is this high-frequency current. Used in the field of skin cosmetology, a large number of literature reports that radiofrequency has the effect of removing wrinkles, improving skin laxity, and improving the quality of the skin, which provides a new step for the development of skin rejuvenation technology.
The application of radiofrequency technology in skin beauty should be often heard of electroporation, electroporation is 02 years ago has been certified by the U.S. FDA and passed the U.S. national 48 patents certified in 2009 by the Chinese SFDA certified radiofrequency treatment equipment. Radiofrequency waves penetrate the epidermal basal melanocyte ` barrier, so that the dermal layer of collagen fibers heated to 55 ° C - 65 ° C, collagen fiber contraction, so that the loose skin wrinkles are tightened, so as to achieve the purpose of cosmetic wrinkles. The representative work is the United States of America's hot cool skin tightening electroporation machine, is a medical version of radio frequency technology electroporation equipment, must have strictly trained doctors to operate, and the machine cost and the use of higher costs, only for medical beauty institutions, a course of treatment effect to maintain 2-3 years or so, the charges range from a few thousand dollars to tens of thousands of dollars, we will be the first generation of this device is defined as a radio frequency cosmetic machine.
The second generation of radiofrequency beauty machine is more common, is the most commonly used in beauty salons radiofrequency beauty machine. The technical point of view is the maintenance version of radio frequency beauty machine, the principle is the same as the medical version, some will join the light energy technology. When the light technology is applied in the radiofrequency beauty machine, the light energy plays the role of a kind of guide, guides the radiofrequency and strengthens the absorption of radiofrequency. Of course, the light energy is absorbed by the epidermal pigments in large quantities, which makes it more risky to treat darker skin. This type of machine is mainly in the beauty salon, the cost of more than 100,000 yuan, the efficacy of the treatment to maintain a few months or a year, a course of treatment fee of about 5000 yuan.
The third generation of radio frequency beauty machine, also known as home radio frequency beauty instrument, is a radio frequency technology as the core of the unipolar radio frequency beauty instrument. It has the advantages of being portable, easy to operate and safer to use. For example, the DR.BAUER divine radio frequency child beauty machine listed in Hong Kong on Christmas Day in 2010. With the characteristics of household and economic set off the home radio frequency beauty instrument snapping up the wind. There are currently three types of radio frequency technology on the market: unipolar radio frequency, bipolar radio frequency and tertiary radio frequency, and unipolar radio frequency is the most clinical evidence to support the most effective.
Through the above content, we should have a more comprehensive understanding of radio frequency cosmetic technology. Radiofrequency technology in wrinkles, blemishes, large pores and other skin problems with excellent results, recognized by the majority of people who love beauty. But the technology is not suitable for everyone to do, such as heart disease, pregnant mothers, injections of liquid silicone are not suitable for the beauty technology.
