Tattoo removal is the process of applying pigment or laser to the skin surface to help fade an existing tattoo. Tattoo ink was specifically made to be absorbed into your body. This means that as you heal from laser tattoo removal, some or all of the pigment may dissipate into your system. The ink particles are small enough to be absorbed by white blood cells and transported to the liver for elimination.
How well tattoo removal works can depend on certain factors like your skin type, how dark the tattoo was initially, and even its location on the body. In most cases, multiple sessions are required. You may experience discomfort due to heat being applied deep into your dermis — the layer of skin just under the surface.
Some areas may also be more sensitive than others, so both the location of the area being treated as well as your pain tolerance will factor into the level of pain or discomfort you might experience.
However, tattoo removal is generally safe and effective.
