Nanoblading is a semi-permanent makeup tattoo technique that uses a fine nano needle. Nanoblading for eyebrows fills in scarce, thin eyebrows for a thicker appearance. The procedure involves the use of pigmented ink and a super fine needle to create hair-like tattoo strokes. These strokes look like natural hair. This technique doesn’t only thicken the appearance of eyebrows, it can also change the shape of your brows. The difference is that nanoblading uses a smaller needle than microblading.
