The principle of diode laser hair removal treatment is based on selective photothermal decomposition. The melanosomes in the hair follicle can selectively absorb the energy of the laser.The laser energy emitted by the machine is easily absorbed by the colored hair follicle without damaging the epidermal tissue. The energy emitted by the laser is absorbed by the hair and the pigment in the hair folicle.It is converted into heat, thus increasing the temperature of the hair follicle. When the temperature rises to a certain level, the hair follicle will be irreversibly damaged, and the hair will lose its original environment and be completely removed. Portable Hair Removal Machine THERMOSTATIC INTELLIGENT REFRIGERATION SYSTEM The instrument is internally loaded with a TEC refrigeration system and an intelligent temperature monitoringsensor to ensure that the water temperature of the machine is constant at 25 °C, make sure that the machine 24 hours of non stop continuous operatio The operator only needs to select the part and skin color to be treat-ed, and the system will automatically generate the recommendedtreatment parameters. Even aninexperienced operator can easilygrasp the operation of the instrument.
