A tattoo is a permanent form of body modification where an artist injects inks and pigments (dyes) into your skin. Tattoo removal is a procedure to remove this permanent ink from your body. Normally, your immune system works to remove foreign particles from your body, but ink particles are too big for your immune system to remove, which is why they’re permanent. Tattoo removal can be a complex process that can take several sessions to complete. This happens because permanent ink granules from professional tattoos exist below your skin’s surface.
