For effective tattoo removal, we typically need at least 6 sessions that are spaced 4-6 weeks apart, making the ink to completely vanish from the skin. However, the removal treatment will take more sessions if the tattoo itself is new or was very recently done. The age of the tattoo, ink colors, and location on the body affects the number of sessions needed for removal, but overall, the older the tattoo the fewer sessions needed as it will vanish more easily.
