Microblading is a semi-permanent tattooing technique that creates hairlike strokes to fill in sparse or thinning brows. .. Unlike a traditional tattoo, which is permanent, the coloring from microblading may last for up to 2 years. This is because microblading uses different tools and a smaller amount of pigment. A skilled esthetician uses a microblade tool to apply color pigments that look like real hairs. The color effect will fade over time, so touch-ups may be necessary to maintain the desired look.
