This Co2 Fractional rf laser utilized 10600nm diode laser, and 3 treatment heads, multi shapes spot size. Can do a good job for acne removal, scar removal and other skin resurfacing treatment. Also can do the vaginal tightening, Vaginal inflammation. CO2 laser machine principle: 1.Fractional resurfacing is a new laser treatment modality that creates numerous microscopic thermal injury zones of controlled width, depth,and density that are surrounded by a reservoir of spared epidermal and dermal tissue,allowing for rapid repair of laser-induced thermal injury. This unique modality, if implemented with proper laser- delivery systems, enables high-energy treatments while minimizing risks. 2.This machine use the RF Tube manufacturerd by Coherent America,the frequency can reach more than 5000HZ,the high speed can work more efficiecnt and effectively,it is very good for the ultra pulse incision for the precise surgey,no blood,the treatment area is very clear,andless down time. 0 Precautions during operation Protection: Protect yourself and the eyes of customers, and wear goggles for customers when operating the face. Prevent operation from hitting eyes. Standard operation: Do not step on the pedal by mistake when not operating in the working state. The handle cannot emit light to positions other than the operating part, such as the body, eyes, instruments, reflective objects, etc. When operating, avoid areas with wounds, blue moles, long-haired moles, and raised moles Adjust the energy, coverage, repetitions, interval time, treatment shape and area to start operation. During the operation, be sure to step on the light after stepping on the skin close to the skin, and do not move the handle during the light emission process. (Movement will affect the depth and density of treatment at the operation site). It is necessary to reduce the energy to operate the weak skin such as cheekbones, forehead, and temples. The operation of the chest, back and inner arms is prone to scar hyperplasia, and the energy density operation needs to be reduced.
