You can expect to undergo four to six laser tattoo removal sessions before your tattoo is gone for good. But several factors will determine how many sessions you’ll need. The tattoo’s age and size, the amount and type of ink used, and the depth of the ink in the skin’s dermis can all affect how long it will take the tattoo to fade after laser treatment.
Blue, black and red inks usually respond best to treatment. Green, yellow and fluorescent inks are typically pretty stubborn. Their absorption spectra fall either on the border or outside of most lasers’ targeted color spectrum. Tattoo inks may even contain chemicals like iron oxide or titanium dioxide, which makes removing a tattoo even more difficult.
You must wait about six to twelve weeks after each laser tattoo removal session until you can receive another round of treatment. During this time your body is slowly absorbing the tattoo’s fragmented ink and carrying it away through the lymphatic system. Soon enough, you’ll start to see your tattoo slowly begin to fade.
