Nano brows are a semi-permanent makeup treatment for the eyebrows that creates the look of extra natural volume, fills in sparse patches, and modifies the shape of the arches into your dream brows. It's a form of cosmetic tattooing – it's done by opening up the skin and depositing color into it, but it's not permanent. The super-fine needle creates hair-like tattoo strokes that can thicken the look of the brows and change the overall shape of your brow. The small needle allows for excellent precision and accuracy to give you natural-looking results.
