If you have light colors in your tattoo, they often consist of traces of white ink. As the white ink oxidizes with treatment, it can turn a grayish color. The best case scenario with oxidized white ink is that more sessions will make it better. However, we can never predict if the grayish color will completely go away. For this reason, we recommend that you avoid tattoo removal if you have white ink, and don’t have the budget to keep getting treatments.
