The name of this beauty trend is misleading: These are tattoos. On your face. But if you fill in your brows every day, you’ll think microblading (which starts at $600) is a stroke of genius. The process can give you the fullest, most beautiful brows, and they last for six months to three years (the semipermanent pigment fades faster if you have oily skin). Your first step is to find a technician you trust. “Look for someone with strong referrals and before-and-after photos that show both brows head-on, so you can judge the symmetry,” says Elli, a certified aesthetician in Toronto. After a consultation to determine shape and color, the technician uses a hand tool to make little cuts in the skin and deposit pigment to look like brow hairs. You’ll be numbed, but it still feels like someone is scratching you with a needle. (Hate needles? Consider this brow treatment.) The cuts then scab, and the pigment will oxidize to a very dark hue, which you’ll have to live with for up to a week because you have to keep the area dry while it heals, Aava says. This means you can’t sweat heavily either. For many people, putting up with temporary Groucho Marx brows to then have perfect arches 24-7 is well worth it.
