The answer is “it depends”. The healing time of a tattoo on the foot depends on many factors such as: the size and complexity of the tattoo, if a black ink has been used (it will heal much faster) or various colors, the type of skin, style of life, your physical condition…Typically, a tattoo should heal on the outer layers of the skin after about two to three weeks, but the full healing process of the tattoo on all layers of the skin will take between four and six months.
