Using this eyebrow cream is easy. First, use the eyebrow knife to trim your eyebrows to your desired shape. Then, dip the brush into the eyebrow cream and start filling in your eyebrows from the inner corner to the outer corner, following the natural growth direction of your eyebrow hairs. Make sure to apply evenly for a natural look. When choosing a color, pick the one that matches your hair color. For example, if you have black hair, 2# black would be a good choice. After use, keep the eyebrow cream in a cool and dry place to maintain its quality. Also, clean the brush regularly to prevent bacteria build - up. Avoid getting the cream into your eyes, and if it accidentally does, rinse thoroughly with water.
