Tattoo removal can be achieved in a number of ways, ranging from laser treatments, chemical peels, dermabrasion, and surgical excision. Lasers are the most common method of tattoo removal performed today. Laser treatments work by targeting the ink particles in the skin with highly concentrated light waves that heat up the ink particles and cause them to fragment into smaller particles that are able to be cleared away by the body's immune system.
Complete removal of a tattoo is usually not accomplished in one laser treatment session. Laser tattoo removal typically requires more than one treatment to reduce the size of the ink particles and make it easier for them to be dispersed by the immune system.
