Using this ETUDE brow mascara is easy. First, make sure your brows are clean and dry. Then, gently comb the mascara through your brows from the inner corner to the outer corner. You can build up the color and intensity as you like. When you're done, just wipe off any excess product. Keep the mascara in a cool, dry place. Avoid getting it in your eyes. If it comes into contact with your eyes, rinse thoroughly with water. And don't share it with others to prevent any potential infections.
