Ensure your eyelashes and eyebrows (if applying) are clean, dry, and makeup-free for smooth adherence. 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. Allow the Long Active serum to fully absorb—apply before bed for overnight nourishment, and consistently use for 4-8 weeks to achieve optimal lash growth and health.
