The hair removal diode laser machine emits a 808nm laser. Through the process of photothermal decomposition, the laser energy can be selectively absorbed by colored hair follicles and the temperature will be increased, so as to remove hair completely.
Since the hair growth cycles can be divided into three periods: growing period, regression period and static period, the laser works only on follicles in the growing period. Hair in the growing period makes up about 1/5 to 1/3 of the total hair on your body. Therefore, it is necessary to treat about 5 times continuously to remove hair completely.
