One of the benefits of microblading is that it doesn't last forever, though it lasts much longer than other coloring options like eyebrow tinting. Professional cosmetic tattooer Bethany Wolosky told Allure, "If you don't touch them up again after 12 to 18 months, they'll eventually completely fade away." But this expected timeline can get cut short under certain conditions. In another interview with Allure, board-certified dermatologist Mona Gohara, M.D., warned readers, "When it comes to pigment, there are slow metabolizers, fast metabolizers, and in-between metabolizers."

This means that some people's brow pigment could take just months to fade while others might last for years. Wolosky elaborated that you can predict how well your skin will hold onto its pigment based on its type. If you have more oily skin than dry, it's likely that the microblading will not last as long. She added that anemia could also cause your body to deplete the iron oxide in the pigment, meaning it would disappear faster. It would be unfortunate to spend money on microblading if it fades quicker than you had hoped, but the nerve-wracking alternative is that it lasts longer than you had wanted.
