Nowadays, there are many tattoos and many people wash tattoos, and the effect of tattoo washing is usually only significant when laser is used. Because laser tattoo washing uses the high energy instantaneously emitted by the laser to make the irradiated pigment particles absorb energy, expand and rupture, part of which splits into smaller fragments and is excreted out of the body, and part of which is swallowed by human macrophages and excreted through the lymphatic system, so as to sweep away the pigment. But laser tattoo washing is not effective at one time, so how many times do you need to do it? Let’s take a look at the following introduction. How many times does laser tattoo washing need to be done? Laser tattoo washing needs to be carried out several times, which is related to many factors. For shallow tattoos, washing once can achieve a very significant effect and even completely subside. However, for tattoos with deep color and parts, washing once is generally difficult to eliminate and requires multiple treatments. Colored tattoos are not easy to remove, while amateur tattoos are mostly shallow and contain carbon pigments. They are light in color and easy to treat. Generally speaking, they only need 4-6 times. The therapeutic effect of laser tattoo washing on tattoos is closely related to the nature of pigment. According to experts, if the pigment particles used by tattoo thorn are fine or the ingredients are relatively pure, its therapeutic effect is also very significant, and most of them can achieve good results in one treatment.
