Tattoos are permanent because an insoluble ink is injected into the dermis, or middle layer of the skin. This is why they remain visible as the particles of ink are too large to be absorbed by the body. Laser tattoo removal uses different wavelengths of light energy targeted toward the specific pigments in each tattoo’s ink. The energy breaks the ink into tiny particles that the body can absorb. From there, the tiny particles are removed through the body’s natural healing responses.
