Nano brows, also known as nano needling, is a relatively new procedure in the beauty industry. It involves using a digital machine with a single needle to create fine hair-like strokes into the skin for a semi-permanent brow. This process is used to enhance the natural shape and fullness of the brows.

After undergoing a nano brows procedure, it's essential to take care of the treated area to ensure the best results. Generally, it's recommended that you avoid washing your brows for at least 24 to 48 hours after the procedure. This is to allow the skin to start the healing process and prevent the pigment from fading or being washed away prematurely.

Once the initial 24-48 hours have passed, you can start gently washing the area with a mild, non-alcoholic cleanser. Avoid scrubbing or using exfoliating products, as these can irritate the skin and disrupt the healing process. Remember, the skin is sensitive after such procedures, and it's crucial to treat it with care.

In addition to this, for about two weeks post-procedure, you should avoid swimming, saunas, or heavy workouts that can cause excessive sweating. Also, avoid direct sunlight and tanning beds as they can fade the pigment and potentially cause inflammation.

Remember, everyone's skin heals at a different rate, so these are general guidelines. Always follow the specific aftercare instructions provided by your beauty specialist.
