An electric tattoo is a tattoo made with an electrically powered tattoo machine. Electricity drives a needle up and down, placing ink in the dermis—the layer beneath the skin’s surface. It is not a tattoo that generates electricity or a separate kind of tattoo.

What does “electric tattoo” mean?

The phrase describes how the tattoo is applied: an electric tattoo machine repeatedly moves a needle to deposit ink in the skin. The U.S. Food and Drug Administration (FDA) describes the needle passing through the epidermis, the outer layer, and depositing ink in the dermis beneath it. FDA: Tattoo Removal: Options and Results

In other words, “electric” refers to the machine’s power and motion, not to an electrical effect in the finished tattoo.

How does an electric tattoo machine work?

A power source runs a mechanism that makes the needle move rapidly in and out. As it penetrates the skin, the needle carries ink below the epidermis and into the dermis. The exact mechanism depends on the machine type.

Rotary machines

A conventional rotary machine uses an electric motor. An offset cam converts the motor’s rotary motion into the needle’s back-and-forth movement.

These are differences in how the needle is driven. The mechanism evidence does not establish that either type is universally safer, less painful, or better for every tattooing task. Portescap: Tattoo Machines: Enhancing Performance and Efficiency with Coreless DC Slotless Motors

Why does tattoo ink stay in the skin?

The needle deposits ink in the dermis, where cells are more stable than those in the epidermis. The FDA explains that this is why tattoo ink mostly remains in place over a person’s lifetime. A tattoo can still change in appearance over time; this explanation concerns why the ink tends to persist, not a guarantee that its appearance will never change.

What safety risks should you know about?

Tattooing punctures the skin barrier. Unsterile equipment or needles can transmit infectious disease, and tattooing can also cause infection, allergic reactions, or other skin problems. The fact that a machine is electric does not make the procedure safe by itself. FDA: Think Before You Ink: Tattoo Safety FDA: Tattoos, Temporary Tattoos & Permanent Makeup

Who regulates tattooing?

In the United States, the FDA says tattoo inks are subject to its oversight as cosmetics, while tattoo parlour practices and the practice of tattooing are generally regulated by state and local authorities. This describes U.S. oversight and should not be assumed to apply in other countries. FDA: Tattoos, Temporary Tattoos & Permanent Makeup
