On average, most patients require 5 to 10 treatments for complete tattoo removal. Patients with older, faded tattoos may need fewer sessions. Patients interested in fading their tattoo for a cover-up tattoo may require as few as 2 to 4 treatments. The number of treatments needed varies case-by-case and depends on a variety of factors including the age of the tattoo, colors of the tattoo, location of the tattoo, the density of the ink, patient health, pre-existing scarring, and more.
