Most people think that laser tattoo is fast and good, but those who have used it will know that there are many things that laser can't do, such as the green color of tattoo, non-chemical pigments and other complex dyeing pigments, which can't be washed off by laser. The color that can't be washed off by laser for three times is difficult to be washed off again, because the working principle of laser is to convert light energy into heat energy, and because chemically synthesized black and red dyes can absorb more energy corresponding to wavelengths, it is easier to be washed off. Laser energy is not enough to affect non-compound pigments, so pigments containing metal atoms cannot be washed away. Laser can't cure "tattoo pigment poisoning allergic rejection syndrome" either, because the potential energy of laser can catalyze toxic pigments, making them penetrate deeper and more difficult to remove. Is there any good way to wash tattoos? At present, it is the graduation job-hunting season, and many college students with tattoos are rejected by enterprises.
