If you’re nervous about getting a tattoo simply because of the commitment, you may be able to get one without worry soon. A team of scientists from New York University are developing a permanent ink that’s actually erasable. The resulting pigment would be easily dissolved with a special solution, and both could be administered by professional artists. The new technology would allow you to revise, add to, or completely remove whatever design you choose, and it won’t leave behind scars like laser removal often does. It’s process is called Ephemeral Tattoo, and it’s still in development.
