Tattoo washing, also known as tattoo removal, is to remove the original patterns on the body through certain technical means. With the rapid development of science and technology, there are many tattoo washing methods. Before understanding how to remove tattoos, we should first understand the basic principle of tattoo removal.
Basic principles of tattoo removal
Human skin is divided into superficial epidermis and lower dermis, in which the epidermis can be updated and shed quickly, while the dermis will not. Tattoo pigments are generally implanted in the dermis, so they are permanent and can not disappear by themselves. Therefore, it is not very easy to remove tattoos.
At present, there are four commonly used tattoo removal methods
Laser therapy: the laser acts on the affected area to break the pigment particles into very small debris, which is discharged through skin eschar removal, or blood circulation discharge and cell phagocytosis to complete pigment metabolism. This method does not destroy other skin tissues and does not leave scars after operation. It is the first choice for the treatment of tattoos, but the cost is slightly more expensive.
Chemical corrosion method: it is to use dilute weak acid solution to cause superficial skin burns and make the pigment fall off with necrotic tissue.
Skin grinding method: it uses a special high-speed rotating grinding wheel to remove the superficial layer of the skin, so as to remove the pigment.
Surgical resection: for deep tattoo patterns, the above methods often have no effect. Surgical resection and suture can only be considered, but scars may be left.
Tips: when using laser, chemical corrosion and grinding methods, each treatment should not be too deep. If the first removal is not clean, the second treatment can be carried out. The interval between each treatment should be 1-3 months. If the cleaning part is not too deep each time, it will generally not leave scars.
