To use this mascara, start by wiggling the brush at the base of your lashes and then pull it through to the tips. This helps to coat each lash evenly. For more volume, you can apply a second or third layer once the first one dries. As for precautions, keep it out of reach of children and avoid getting it into your eyes. If it does get in your eyes, rinse thoroughly with water. When it comes to maintenance, always make sure to close the cap tightly after use to prevent the mascara from drying out. Replace it every three to six months for the best results.
