The tattoo removal solution is tattooed into the skin in order to effectively come into contact with the unwanted ink. Once that occurs, the tattoo removal solution is able to bind to the unwanted ink and draw it out of the skin in a chemical extraction process. For this reason, acid peels, retinoids, or any products that are marketed as topical tattoo removal solutions are simply ineffective because they work at the surface of the skin (the stratum corneum) and not the dermis where the ink is likely to be embedded. At most they’ll just minimally lighten and eventually dull the color, which is what happens gradually over time anyway as the skin continually sheds and grows out.
