It seems that I want to have a facelift. I'll give you the information I found. Tattoos belong to an exogenous pigmentation. Tattoo pigment enters the skin at will, and sometimes goes deep into the dermis and fat layer. Modern laser provides an ideal method for tattoo removal. Laser can instantly crush and explode high-energy pigment particles, and the crushed pigment fragments can be excreted through scabbing or cell phagocytosis and lymphatic blood circulation. The effect of laser is very selective, and it will not cause harm to the surrounding normal skin, and there is no obvious side effect after tattoo removal, and no scar will be left, but some people with scar constitution may have scar reaction. Generally speaking, once shallow tattoos are treated, the effect of tattoo removal is obvious, or even completely eliminated, but most of them usually need multiple treatments. Because the effect of tattoo removal is closely related to the nature of tattoo dyes, ordinary tattoos usually need multiple treatments because the tattoo dyes used are mostly ordinary ink, which is not only coarse in particles, but also contains a lot of impurities, and some patients may need longer treatment. In addition, the treatment of color tattoos is more difficult than monochrome tattoos and requires more treatment times. The interval between laser tattoo removal is three months.
