Q-switch Nd: Yag laser removes tattoos by emitting very short light impulses (nanoseconds), which are selectively absorbed by the tattoo's dye. Each colour of a dye absorbs different length of the wave. After absorption, there is the dye tearing into very tiny fragments, which are absorbed (removed by the skin immune system). Because of that, the treatment is more precise and doesn't cause permanent skin damage.
Not all dye colours can be removed. Laser has some limitations when it comes to removing yellow, purple, orange, pink and white tattoos. With this system you can remove professional, amateur and post-traumatic tattoos.
Course of the treatment
The performed treatment is a counsel with the laser attempt qualifying to the treatment. Feelings during the treatment with the laser can be compared to the pain of shooting someone with a rubber band, so the anaesthetisation is usually not required. After the treatment there are delicate, surface and fast healing cuticle damages. Before leaving the clinic, you have an antiseptic ointment and dressing placed on your skin. After several days the scabs fall down leaving the reddened cuticle. With every treatment the tattoo is fading, but sometimes a small amount of dye may remain in the skin and the shape of a tattoo might be visible.
There is a very low risk of scars, except too early tearing off scabs and potential infection (rarely). Almost after every treatment of removing tattoos there are temporal discolorations, depigmentations and changes in the skin's texture in the treated area. In most cases they disappear after 1-3 years after the treatment. In rare cases there occur permanent changes, which are usually delicate and almost not visible and thus accepted by patients.
Removing tattoos in only one treatment is almost impossible.
The number of required treatments depends on:
- colour or number of colours in the tattoo,
- size, density of the dye,
- type of the dye,
- depth of the tattoo,
- skin colour
- individual reactions to the laser (role of the immune system);
- Amateur tattoos require 4-5 treatments to remove them in 90%.
