Laser therapy is to apply laser to the affected area, break the pigment particles into tiny pieces, and discharge them through skin scabbing, or discharge them through blood circulation and phagocytosis to complete pigment metabolism. This method does not destroy the rest of the skin tissue, leaving no scars after operation. It is the first choice for tattoo treatment, but the cost is slightly more expensive.
Commonly used tattoo washing methods mainly include chemical etching, laser cauterization, liquid nitrogen freezing, skin grinding, excision and suture, skin grafting and so on.
Extended data:
Laser tattoo washing can selectively use lasers with different wavelengths without damaging the skin. This method of tattoo washing is to inject light into the dermis, turn pigment particles into powder, increase the high jump between them, and then be absorbed and removed by macrophages. If the tattoo pattern is dark, it can be repeated many times, constantly changing the wavelength of light.
Dermatologists admit that laser tattoo will leave deep or shallow spots on the treatment site, but this is better than leaving scars and tumors. This tumor is a trace left by surgery or carbon dioxide laser tattoo. Traditional laser tattoo washing is very harmful to the skin.
The most obvious advantage is that laser tattoo washing does not need to use knife cutting or abrasion, and in most cases, tattoo washing will not leave obvious scars. Of course, the way to wash tattoos is not a magic eraser. Tattoo washing does not require local anesthesia, which is another advantage of laser scar removal and other scar removal operations.
