Human skin can be divided into superficial epidermis and subcutaneous dermis, in which epidermis can be rapidly renewed and shed, while dermis cannot. Pigments in tattoos are usually implanted in the dermis, so they are permanent and will not disappear on their own. Therefore, it is not easy to get rid of tattoos.

At present, the commonly used methods to remove tattoos are:

1, phototherapy: the laser acts on the affected area, crushing the pigment particles into tiny pieces, which are discharged through skin scabbing or blood circulation, and the cells are phagocytized 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 tattoo treatment at present, but the cost is slightly expensive.

2, chemical corrosion method: it is to use diluted weak acid solution to cause superficial burns on the skin, so that the pigment falls off with the necrotic tissue.

3. Skinning method: It is to remove the surface layer of skin with a special high-speed rotating grinding wheel to achieve the purpose of removing pigment.

4. Surgical excision method: For deep tattoo patterns, the above methods are often ineffective, and only surgical excision and suture can be considered, but scars may be left.

When laser, chemical etching and grinding are used for treatment, each treatment should not be too deep. If the first cleaning is not clean, the second treatment can be carried out, and the interval between each treatment should be 1-3 months. If the cleaning area is not too deep each time, there will generally be no scars left.

In addition, it should be reminded that when removing tattoos, you must choose a regular hospital, and the plastic surgeon will choose the most suitable treatment method according to the actual situation to achieve the ideal effect.
