This New Technique Can Make Painless, Blood-Free Tattoos A Reality

When the patch's microneedles pierce the skin, they disintegrate, releasing the ink and applying the tattoo.

Scientists have developed a method for creating tattoos without pain or blood, and they believe it may have both medical and aesthetic uses. 

The Georgia Institute of Technology in the US has developed the technology that may soon lead to simple tattooing operations. The procedure involves applying ink to the skin using tattoo patches with microneedles.

Microneedles are used in this self-administered method to imprint a design into the skin without causing discomfort or bleeding. 

“We've miniaturized the needle so that it's painless, but still effectively deposits tattoo ink in the skin. This could be a way not only to make medical tattoos more accessible, but also to create new opportunities for cosmetic tattoos because of the ease of administration,” said Mark Prausnitz, who was in charge of the project at Georgia Tech.
