Surgical methods. Official website of Liaocheng Central Hospital showed that Liaocheng Central Hospital washed tattoos through surgery. This is determined by the location, size, depth and pattern of the tattoo. If the pigment is light, you can only remove the tattoo from the nipple layer to the subdermal layer, and removing the tattoo will not leave a scar. If the pigment is deeply colored and penetrates into the dermal reticulation to subcutaneous fat, it is necessary to remove the whole skin or even subcutaneous fat, but it may leave scars after operation.
