New Tattoo Ink Disappears in Sunlight, Lasts 2.2 Years in Skin
Researchers have developed a tattoo ink that vanishes when exposed to sunlight but remains switchable in the skin for up to 2.2 years. Unlike traditional tattoos that require painful and costly laser removal, this innovative ink allows body art to be turned on for occasions and disappear by morning, offering a flexible alternative to permanent tattoos.
