The general tattoo methods are laser method (laser tattoo needs cold light) and pickling method. Laser washing generally leaves traces, while pickling may leave scars. Moreover, no matter how good the hospital washes tattoos, you can't wash them all at once. Wash it at least two or three times until the color becomes lighter, but it is impossible to wash it as clean as the skin before the tattoo.

If you don't like the tattoo picture, and the pattern is not too big and complicated, you can change the picture, that is, modify or cover the new picture on the basis of the original picture, which will also make the tattoo look good, but no matter how good the technology is, it will still leave traces.

If you wash your tattoo, don't go to the beauty salon on the street. Most of them are cheated and can't be washed away, and they can't guarantee hygiene. If you want to wash your tattoos, go to a local regular hospital. Generally, hospitals with dermatology or cosmetic plastic surgery programs can wash tattoos. In addition, some professional tattoo shops can also wash tattoos, but most tattoo shops now only do tattoos, and few can wash tattoos. The landlord should go and ask first. But no matter where you wash tattoos, the price will be much more expensive than tattoos, and washing tattoos is more painful than making tattoos.
