Because before laser tattooing, you need professionally trained personnel to adjust the laser parameters according to the color depth, area and skin condition of your tattoo. If the operator is unprofessional, then the grasp of the laser is not in place, and the laser parameters may be adjusted improperly.
If the laser parameters are too high, it may burn the skin; If the parameters are too low, the effect of tattoo washing will not be achieved. At the same time, laser tattoo washing is based on the actual situation of individual tattoos, so it is highly targeted.
The tattoo washing methods such as liquid medicine and skin grafting will definitely leave scars. If you are not clear, you can ask me by name.
