There's no evidence that tattoo removal creams work. At best, tattoo removal cream might fade or lighten a tattoo. The tattoo will remain visible, however, and skin irritation and other reactions are possible.
Remember, tattoos are meant to be permanent. Because the ink is placed beneath the top layer of the skin, complete removal of a tattoo is difficult.
If you're interested in tattoo removal, don't attempt it on your own. Ask your dermatologist about laser surgery or other options for tattoo removal.
