Factors affecting efficacy
In clinical practice, the number of treatments for different tattoos varies greatly, ranging from several to ten times. Even some tattoos cannot be removed after dozens of treatments. The main factors affecting the efficacy of laser removal of tattoos are:
1) The nature and timing of tattoos Professional tattoos are more difficult to remove completely than non-professional tattoos. The longer the tattoo, the easier it is to remove.
2) The color of tattoos Compared with black and blue tattoos, red, yellow, and green tattoos are more difficult to treat.
3) The composition of the pigment particles. Pigments with complex compositions have different responses to lasers. It is difficult to choose the laser type and energy density, and it often requires multiple laser treatments.
4) The number and thickness of pigment particles accumulated in the dermis. The greater the density of tattoo pigment particles, the thicker it is, the more difficult it is to treat.
5) Pigment particles are different in size. Some pigment particles are too large, and it is difficult for the laser to completely crush them, and it is difficult for macrophages to swallow them. Generally speaking, professional tattoos have larger pigment particles and contain organometallic dyes placed deep, while amateur tattoos have smaller carbon-based ink particles, so professional tattoos are more difficult to remove.
6) Depth of pigment particles. For those with deep positions, laser treatment is difficult to reach the corresponding level, and most require multiple treatments.
7) The treatment parameters of the laser have the greatest influence on the wavelength, pulse width and energy density of the laser. Only by choosing an appropriate laser can a good treatment effect be achieved.
Tattoo removal has high requirements for laser equipment and medical technology. Friends who are troubled by tattoos must choose a formal medical institution and be treated by professional doctors to avoid scars and regret for life.
