The principle and care points of laser tattoo removal

  The laser is based on the principle of selective photothermolysis and color complementation. The laser wavelength is selected according to the tattoo color to remove the pigment. That is to say, the tattoo pigment particles in the skin absorb the instant high energy of the laser under the Q-switch laser irradiation The pigment particles vaporize and are fragmented, while the cellular framework can be retained intact. At the same time, because the laser pulse time is shorter than the thermal relaxation time of the skin tissue, the instantaneous single-pulse laser energy release process is completed within about one millionth of a second, so that the newly generated heat is not transmitted to the surrounding tissues and epidermis, and the lesion tissue is While the heat effect is eliminated, the surrounding healthy skin tissue will not be destroyed. In the subsequent inflammatory reaction process, part of the particulate debris directly enters the lymphatic capillaries and is filtered and eliminated, and part is swallowed by macrophages, degraded and discharged by acid hydrolase. The cells that have been cleared of pigment particles can be quickly repaired on the basis of a more complete cell framework. The longer the wavelength, the deeper the tissue depth of the laser action, and the color particles of the tattoo are all in the dermis. Therefore, the longer wavelength has a greater impact on the melanin of these dermal tissues, but has little effect on the epidermis.

  Attention should be paid to the care after laser treatment:

  Apply chlortetracycline ointment to the wound surface to keep the wound surface dry and clean. Generally, no dressing is used. If the wound is large or not easily exposed, it can be appropriately bandaged. At the same time, give oral antibiotics such as lijunsar, cephalosporin, etc. to avoid sun exposure and severe exposure. Exercise and ban cosmetics to avoid hyperpigmentation on the wound.

  The disadvantage of laser is that it is expensive and time-consuming. However, the patient suffers little pain and injury, and female patients are especially inclined to laser treatment. Generally 3 laser treatments for tattoos are enough. Depending on the size of the area, the cost varies. The price of a regular hospital is about 1cm*cm 500 yuan per time, which is more expensive than a tattoo.
