Most colours can be treated. White, yellow and other bright colours can prove difficult, but cover-up treatments can remedy this. If we are concerned about a certain colour we will tell you and carry out a test patch to check before proceeding. Laser treatment will only work on a certain amount of ink each time so several sessions could be required to work through the colours. The tattoo will fade after each treatment. The number of treatments required can depend on how quickly you heal, how deep the tattoo is in the skin, the type of ink used and other factors. Older and faded tattoos can be easier to remove.
