The general tattoo methods are laser (laser tattoo needs cold light) and pickling. Most of them will leave marks after laser washing, while pickling will leave scars. Moreover, no matter how good the hospital washes tattoos, you can't wash them all at once. You have to wash it at least two or three times to get a light color, but you can't wash it completely like the skin before tattoo.

If you wash your tattoo, don't go to the beauty salon on the street. Basically, you can't wash the money after cheating, and the hygiene can't be guaranteed. If you wash tattoos, go to a regular big 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 your body is more painful than tattoos.
