Hi thanks for your question. Typically after any laser tattoo removal session temporary skin discolouration as well as a lightening of the tattoo is normal. You will almost always need more than one session to remove a tattoo altogether. Removing tattoos is complex, it's dependent on a variety of factors such as the colour of the tattoo, its size, age, depth, particle size and your skin tone. Typically to remove a tattoo completely you will need several treatments spaced approximately 8 weeks apart, so it's a bit of a long journey. But yes with an expert provider and the best technology it is possible to permanently remove your existing tattoo. Please speak to your provider if you have any further questions or concerns.
