Use the brush or wand tip to apply a small amount of serum to the base of your lashes, then comb from root to tip for even distribution. For enhanced nourishment and volume, apply one layer, let it dry, and follow with a second layer. Apply twice daily—use Cosnori Tinting Eyelash Serum during the day and Cosnori Transparent Active Lash Serum at night for best results. You can also apply the serum to your eyebrows if desired for additional care.
