Laser tattoo washing is a popular tattoo removal method at present. It takes advantage of the characteristics that laser can crush and explode pigment particles in an instant with high energy. Crushed pigment fragments can be removed from the body by scabbing or phagocytosis and lymphatic blood circulation. Without pigment particles, the color of tattoos will become lighter or disappear. Generally, shallow tattoo treatment can have a good effect once, or even be completely eliminated, but most of them need multiple treatments.

This is because most tattoos are tattooed with ordinary ink. This kind of ink not only has coarse particles, but also contains a lot of impurities, so it will be more difficult to handle, and it will have to be treated several times. Generally, color tattoos are more difficult to treat than monochrome tattoos, and the time interval of laser tattoo washing takes dozens of days.

Experts from Changchun 208 Hospital pointed out that although most tattoos need multiple treatments, they generally do not leave scars. This is because the role of laser is highly selective and will not damage the surrounding normal skin, so it will not leave scars. But not necessarily for special traumatic tattoos, such as close-range explosion, which may cause carbon particles to penetrate into the skin, or paint, plastic, metal, dust, sand and other particles to penetrate into the skin during traffic accidents. The pigment of these traumatic tattoos enters the skin at will, and sometimes goes deep into the dermis and fat layer.
