Old tattoo faded over time (couple of decades or so) due the immune system constantly breaking down the ink's pigments and metabolized them through the liver. For those who wants to expedite the removal process in months instead of years, tattoos can be removed with either with 1st generation (Q-Switched or Nano) or 2nd generation (Pico) laser technology. If tattoo is new, you'll want to wait until it's completely healed (around 2-3 months) before laser treatment. The number of treatment is depending on various factors (lighten for cover up vs complete removal, laser technology, physician's experience, tattoo size, ink saturation, colors, overall health, skin type, tattoo location, etc).. Turquoise is quite challenging but removalable given enough time and the right technology! White however is virtually impossible to be removed. We have utilized both Nano/PICO technology and PICO is costlier; but removes tattoo much more efficiency with less discomfort. We recommend seeking laser tattoo removal treatment from a reputable professional healthcare provider in your area who is specialized in tattoos removal with both Nano/Pico technology.
