Once you get a tattoo, don't wash it easily. Usually, no matter what color the tattoo is, it will leave a mark if it is washed lightly, and a scar if it is washed deeply. Tattooing methods generally include laser method (laser tattooing requires cold light) and pickling method. Laser washing usually leaves traces, and 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 three times to get a light color, but it is impossible to wash it as clean as the skin before 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 wash tattoos, go to a regular big hospital. Generally, hospitals with dermatology or cosmetic plastic surgery programs can wash tattoos. But no matter where the tattoo is washed, the price will be much more expensive than the tattoo, and no matter which method is used to wash the tattoo, the pain is greater than the tattoo, so it is best to think it over before deciding.
