Scientists Develop Painless Tattoos That Can Be Self-Administered
Tattoos are used in medicine for multiple purposes. These include covering up scars, guiding repeated cancer radiation treatments, or restoring nipples after breast surgery. Tattoos can also be used instead of bracelets as medical alerts to communicate serious medical conditions such as epilepsy, diabetes, or allergies.Various cosmetic products using microneedles are already on the market — mostly for anti-aging. However, developing microneedle technology for tattoos is new.
In this way, the microneedles can be pressed into the skin just once and then dissolve. They leave the ink in the skin after a few minutes without bleeding.Although most microneedle patches for pharmaceuticals or cosmetics have dozens or hundreds of microneedles arranged in a square or circle, microneedle patch tattoos imprint a design that can include letters, numbers, symbols, and images.
The study demonstrated that the tattoos could last for at least a year and are likely to be permanent. This also makes them viable cosmetic options for people who want an aesthetic tattoo without the risk of infection or the pain associated with traditional tattoos. Microneedle tattoos could alternatively be loaded with temporary tattoo ink to address short-term needs in medicine and cosmetics.
