The biggest advantage of the tattoo machine's working mode is that it can generate high speed and large torque without being driven by motor or motor, and the power consumption of motor or motor is not considered. When working, the tattoo needle punctures the epidermis at a high speed and evenly. The tattoo pigment is implanted into the basal layer of the epidermis, so that the pigment can be permanently fixed on the epidermis, forming beautiful patterns and characters of various pigment combinations, so as to achieve the effect of modifying the skin and covering the epidermal scars.
