New tattoo removal laser blasts inkings trillions of times a second

A cutting-edge laser gun that blasts the skin trillions of times per second can completely erase tattoos – yet causes little pain and leaves no scars.

The LightSense system, the first innovation in tattoo removal for a decade, has proven in clinical studies to be highly effective, and works well even on black and brown skin – something that used to be difficult, if not impossible.

Tattoos are created by punching ink into the dermis – the middle layer of skin – with a needle. Due to the large size of the ink particles, the immune system is unable to break them down, so cells known as microphages surround the ink and stay in place, naturalising it. As a result, the tattoo design is trapped in the dermis.
