The location of the tattoo on the body, does in fact affect how quickly the ink will clear the skin. More vascularized area, like the head and neck will clear the broken ink particles much quicker than say a tattoo on a foot that is far away from the heart. The closer to the heart and above the heart the quicker the clearance. Due to longer circulation routes and gravity, tattoos at the ends of extremities can take a bit longer to clear.
