thINK Tattoo Removal
During tattooing, ink is injected into the skin. The ink initiates an immune response, and cells called "macrophages" move into the area and "eat up" the ink. The macrophages carry some of the ink to the body's lymph nodes. But some of those macrophages that are filled with ink stay put, embedded in the skin. That's what makes the tattoo visible under the skin.
