The Neutrogena Makeup Remover Eraser Stick is a product that extracts makeup from your face, it is a corrector used to level makeup on your face when you make mistakes. So the first thing you need to do is grab your pen and open it. Then the second step is to gently rub the tip of the pen on the excess makeup, make sure you do not over do it because then you might take off more make up than necessary. You can twist the eraser stick to get more of the eraser to use. After you are done, don't forget to close the eraser and enjoy your fresh make up! This product is highly rated on Amazon and I can't recommend it enough.
