Unlike an eyebrow pencil that you wipe off at night before you go to sleep, eyebrow microblading is a semi-permanent tattoo procedure where a special handheld microblading eyebrow pen is used to draw on strokes that mimic the appearance of real brow hairs, While it's a similar process to getting a tattoo, the ink that is used is far less concentrated than that of a regular tattoo and is specifically formulated for the microblading process.
