Longer, thicker, and stronger lashes every day. This serum lengthens and volumizes lashes, making them look fuller and healthier. A must-have in your daily beauty routine. How to use: Thoroughly clean eyelashes and eye area. Apply the serum twice a day, in the morning before makeup and at night before bed. Dip the brush, remove excess, and apply to the base of the upper lashes. Slide the applicator from the tear duct to the outer corner of the eye, along the lash line. Let it dry for a few minutes before applying other products. Do not rinse.
