Nano brows, also known as nano needling or nano blading, is a semi-permanent cosmetic tattooing technique that creates the illusion of fuller, more defined eyebrows. This procedure is done with a nano brows machine, a device that uses ultra-fine nano needles to deposit pigment into the skin. Here's what you need to know about the machine and the procedure:

1. **The Nano Needles:** The nano brows machine uses needles that are significantly smaller than those used in traditional microblading. These needles, often 0.18mm or less in diameter, allow for precise, detailed work. Because of their size, the nano needles cause less trauma to the skin, which can lead to a more comfortable experience and potentially faster healing time.

2. **The Procedure:** During a nano brows procedure, the technician uses the machine to create tiny, hair-like strokes in the skin. These strokes are filled with pigment, which is deposited into the superficial layers of the skin. This results in a semi-permanent tattoo that mimics the appearance of natural eyebrow hairs.

3. **The Pigment:** The pigment used in nano brows is typically mineral-based, which is considered safe for the skin. The color of the pigment is chosen to match or complement the client's natural eyebrow color.

4. **The Healing Process:** The healing process after a nano brows procedure is generally quicker and less uncomfortable than after traditional microblading. This is because the nano needles cause less trauma to the skin. However, proper aftercare is still essential to ensure the best results.

5. **The Results:** Nano brows can last anywhere from 1 to 3 years, depending on various factors such as skin type, lifestyle, and aftercare. The results are natural-looking eyebrows that require minimal upkeep.

6. **Safety and Hygiene:** As with any procedure that breaks the skin, there is a risk of infection. Therefore, it's crucial to ensure that the nano brows machine is properly sterilized before use, and that the technician follows all safety and hygiene protocols.

To conclude, the nano brows machine is a tool that allows for a more precise, less invasive form of semi-permanent eyebrow tattooing. As with any cosmetic procedure, it's important to do your research and choose a reputable, experienced technician to ensure the best results.
