Microneedle tattoo technique could make tattooing painless and fast

Scientists at Georgia Tech say press-on innovation opens opportunities for medical and cosmetic use

Painless, bloodless tattoos have been created by scientists, who say the technique could have medical and cosmetic applications.

The technique, which can be self-administered, uses microneedles to imprint a design into the skin without causing pain or bleeding. Initial applications are likely to be medical - but the team behind the innovation hope that it could also be used in tattoo parlours to provide a more comfortable option.
