Eyebrow microblading, microstroking, brow embroidery, feather touch, hair strokes, 3D brows, HD brows? It's all the same thing! There are many names for the same technique, but it is most commonly known as microblading. However, this name implies that there is a blade being used, and that is most definitely NOT the case! This manual method of tattooing or permanent cosmetics in the brow area uses a hand tool that contains a row of very fine needles:
These sterile, single-use needles are dipped into pigment, and then using gentle pressure, the artist scratches them into the skin, creating strokes that mimic brow hairs. The pigment should be implanted into the same depth of skin that any other tattoo is, but since there is such a low concentration of pigment, it will fade much more quickly.
There are machine methods now that can offer similar results, but not all needles are created equal. Some artists use a thicker needle that leave thicker strokes, and when not done correctly, they can leave blots/dots at the base of the stroke. For the most natural look, either make sure it is the manual hand method, or if done by machine, look for the word "nano" (this will be the smallest needle size).
I personally prefer to call it microstroking, but whatever you call it, make sure that the artist you choose is certified, skilled, and clean. Do your research, look at photos of their work, and book a consultation to get to know their style and vision for your brows. Remember, this service is not for everyone, and at the end of the day, it is a tattoo. Don't EVER book a service just because it is the cheapest -- your face deserves better!
