This instrument is mainly based on aviation technology. When sterile physiological saline and oxygen are introduced into the air compression equipment at the same time, tiny water droplets will be sprayed by a specially designed nozzle at a speed of 200 m/s in the form of spray. Using this instrument to treat the affected area has no pain and good peeling effect. From epidermis to dermis, treatment can be carried out according to the specific requirements of patients. This instrument has a wide range of uses, which can be used to supplement nutrition alone, and can also be used for skin regeneration care after intense pulsed light (IPL) surgery, and it is also an indispensable equipment for hair removal care.
