Tattoos can be covered by ironing, but this is not a smart way. Because the scars on the body surface, including scalded scars, will affect the physical examination and recruitment of civil servants, which is even more unsightly. In addition, scalding is easy to cause infections and other diseases, and this method is not desirable. Ordinary blue-black tattoos can be removed by laser, and almost no scars can be seen. If you want to remove the tattoo in a short time, you can remove it by surgery. I suggest you consult a plastic surgeon face to face to avoid new ones.
