The permanent nature of tattoos make getting one a huge decision, maybe now that can be an easier decision because of a removable, natural ink. Before it would take several painful laser treatments and still leave scarring to have a tattoo removed. But today scientists from Havard Medical School, Brown University, and Duke University have engineered a safe, permanent, easily removable tattoo ink. With one simple, short laser treatment the ink disappears, as if never there, and if the tattoo was done correctly there should be no scarring left behind.
This ink is basically tiny microcapsules of natural pigments. In the picture you see a brown iron-oxide and orange beta-carotene pigments encapsulated in tiny polymer beads. Not only is this compound removable but it is also the safest. Since the tattoo industry is not regulated by the FDA there can be all kinds of heavy metals, chemicals, even carcinogenics in the current inks. Although most people who get tattoos never have a reaction but there are still a large number of people who do, by creating a safer ink hopefully this number will decline.
Cosmetic reasons are not the only reasons behind the creation of this gentler, easier ink. Health problems can occur from tattoos, such as continued infections and allergic reactions. They can overcome the tattooed area of the body and become a health hazard for that person. By being able to easily remove the ink, the issues can be quickly resolved.
This technology won’t save the world but it can make a big difference to someone suffering physical or mental duress due to a tattoo.
