Using this DEROL eyeliner is a breeze. First, make sure your eyelids are clean and dry. Then, hold the eyeliner pen like a regular pen and draw a thin line along your lash line. You can start from the inner corner of your eye and work your way out. For a more dramatic look, you can thicken the line at the outer corner. Remember to close the cap tightly after use to prevent it from drying out. Keep it in a cool, dry place away from direct sunlight. If you get the eyeliner in your eyes, rinse immediately with plenty of water. Enjoy your beautiful and long - lasting eye makeup!
