The minimum time required between laser tattoo removal treatments is around six to eight weeks for most patients, with lighter complexions closer to the six week mark and darker complexions closer to the eight week mark. This amount of time is required to allow the body’s immune system to flush away ink as well as sufficient time for the skin to heal between treatments. Receiving the treatments too close together does not allow the body enough time to remove the ink that was broken down at the most recent session and can cause damage and permanent side effects to the skin. For ideal results, it may be recommended to wait up to three months between treatments.
