What would it mean if serious diseases or issues could be detected quickly just by looking at your skin? Well, a team of researchers is now testing these medical tattoos to help us be fitter and healthier human beings!

While medical tattoos may seem like a thing more akin to sci fi movies, these tattoos change colour to track your health, such as letting you know if you’re dehydrated or had a drop in blood sugar. Amazing for someone with diabetes!

Researchers at MIT and Harvard are currently at the testing phase (on pig skin).
