Lemon juice is one home remedy for permanent tattoo removal. Lemon is a natural bleaching agent. It is a natural cleaner, so you can use it to wipe off and get rid of tattoo ink. This method is safe for people with small, light-coloured tattoos.
However, note that bleaching agents, especially lemon, can irritate your skin. Make sure this won't make matters worse than just going to a tattoo removal professional in the first place.
