At present, there are many fake ultrasonic methods on the Internet. The method of removing bags under eyes by ultrasonic wave is described as the same process as laser method and radio frequency method. This means that the deer is a horse, and the reputation of removing bags under the eyes by ultrasonic wave is used to promote the radio frequency method or laser method. Please pay attention to consumers: the ultrasonic method is a national patented technology. The ultrasonic method without the authorization of Dr. Liang is fake, which may be a little cheaper than the real ultrasonic method, but the price of the real ultrasonic method is 4300 yuan. The following is excerpted from official website's ultrasonic pouch removal. Ultrasonic pouch removal is the only non-invasive and non-trace pouch removal operation at present. Principle: Using ultrasonic vibration emulsification principle to emulsify the fat in eye bags and absorb it through special eye mask. Different tissues and cells of the human body have their own fixed ultrasonic vibration frequency, so do the fat under the eyes. When the ultrasonic frequency emitted by the ultrasonic instrument is equal to the fat under the eyes, the fat under the eyes will vibrate. When the energy density of vibration reaches a certain level, the cell membrane of the fat under the eyes will be destroyed and emulsified. In this way, the fat cells in the eye bags are eliminated in a targeted way, so as to ensure that other cells around them remain intact and are not harmed by the frequency of current ultrasonic waves, and the purpose of destroying only emulsified fat cells in the eye bags is achieved. When the fat in the eye bags is destroyed and emulsified, it is absorbed into the body through a special eye mask to achieve the purpose of removing the eye bags. This method has no trauma and sequelae. It is the most advanced and popular method to remove bags under eyes, and it is also the safest, painless and traceless method to remove bags under eyes.
