q switch nd-yag laser manufacturers tell you that a tattoo is a pattern or pattern created by piercing the bottom layer of the skin with a needle with ink. Many people use tattoos to express their beliefs, worship, or simply to show their unique personality and self. However, most of the tattoos show the decision of the tattooer at a certain stage of life. Over time, people's tastes will also change, which makes a large number of tattooers have a need for tattoo removal.

Compared with the tattoo itself, it is obviously more difficult to remove the tattoo, which is determined by the characteristics of the tattoo itself. q switch nd-yag laser manufacturers tell you that when the tattoo is completed, the pigment is not only attached to the bottom layer of the skin, it will undergo a series of in vivo migration and precipitation, from the cytoplasm of the stratum corneum along the granulation at the dermis-epidermal junction tissue, and eventually into the fibroblasts of the dermis, making the removal of pigment from tattoos more than it seems. In addition, various tattoo pigments of unknown composition on the market also bring possible side effects to tattoo removal, including allergic granulomas, secondary skin infections, and various pigments containing heavy metals (red-mercury, yellow-cadmium, blue color-cobalt) caused by allergic dermatitis and so on.
q Switch nd-yag laser manufacturers tell you that some outdated technologies will intentionally damage the epidermis, such as chemical corrosion, thermal burning or electrophoresis, and the exudation stage after epidermal destruction will cause the pigment to migrate to the wound surface, and then absorb and absorb through medical means. discharge. Obviously, these methods cause a lot of pain, and the methods are crude and the results are unpredictable.
In the early 1970s, lasers were tried to remove tattoos. The first use was a CO2 laser. Although this laser can indeed destroy the ink in cells, it can also cause excessive damage to the skin, destroy tissue structure and form a large number of scars. . Compared with CO2 lasers, q switch nd-yag lasers, which were only applied to medical aesthetics in the 1990s, showed better clinical effects, clear predictability and good safety.
The q switch nd-yag laser can output high-intensity light energy pulses in a very small time width (<10ns) by controlling the Q switch. The short heating time can ensure that the skin does not cause tissue damage due to burning, and the high-energy pulse can effectively smash the deep ink. The smashed ink particles will be swallowed by macrophages and cleared by the body's natural immune process.
