Tattoos consist of thousands of particles of tattoo pigment suspended in the skin. While normal human growth and healing processes will remove small foreign particles from the skin, tattoo pigment particles are permanent because they are too big to be removed. Laser treatment causes tattoo pigment particles to heat up and fragment into smaller pieces. These smaller pieces are then removed by normal body processes.
Before you decide to remove your tattoo, it is important to consider the following.
1. Removal takes time, sessions must be spaced apart to avoid any damage to the tissue. In this waiting period, the particles are still working down to smaller sizes.
2. Some colours are much harder to remove then others. Black is the easiest colour to remove, with reds and greens being the hardest.
3. Complete removal can take a long time, sometimes up to a year. It is important to remember that sometimes complete removal is not possible.
4. Laser removal is always your best bet before attempting to cover a tattoo. Removing to cover means the ink only needs to dull down, so the process is much quicker than complete removal.
