Ultrasonic scalpel and water needle cannot be done at the same time, because doing it at the same time will inevitably cause secondary damage to subcutaneous tissue. If you have to do it alone, the water needle is a few hundred yuan cheaper and about 5,000 yuan as expensive as Filoga, which can be used for several months at a time. The disadvantage is that repeated water injection will cause damage to facial skin. When the water needle on the face is completely metabolized, you can actually make an ultrasonic scalpel. It is best to make genuine ultrasonic scalpel. The price of making a genuine ultrasonic scalpel is generally between 3 and 3~5w. Although the ultrasonic scalpel is non-invasive, it stimulates the subcutaneous dermis. Therefore, it is necessary to use the ultrasonic scalpel in conjunction with the FOHO photoelectric restorer within one year after operation to completely repair the subcutaneous injury. When taking this kind of professional-grade restorative products orally, we must pay attention to whether there is FDA certification. FDA is the certification standard of food and drug administrations all over the world. That is, it has no effect.
