We know what you're thinking: tattooed eyebrows? No way. But hear us out. Microblading leaves brows looking natural, not scary, said Jen Terban-Hertell, co-owner of East Side Ink, the celebrity-approved tattoo parlor in New York City. Microblading is done with a hand-held tool — it "looks like an X-ACTO knife made out of needles," she said — that puts pigment into the skin, but doesn't go as deep as a normal tattoo would. It's also semi-permanent. Your microbladed brows should last between one and three years, Terban-Hertell said, adding that 18 months is typical for most of her clients. The procedure differs depending where you go, but she sees people twice — once for an initial appointment and then once the brow has healed for a touch-up.
