Numby Stuff is a quick and effective way to numb an area of skin by a painless, needle-free procedure called iontophoresis.
Iontophoresis uses a mild electrical current to transport medication into the skin.
It has been approved for all ages. The unit generates a mild electrical current to transport medication into the skin. To some children the treatment feels like a tingling or a warm feeling under the patches which decreases or disappears after a few minutes. After a few minutes, the skin will appear white where the Numby Stuff has been. This color is followed by a period where the skin appears red.
