Intensive Eyelash Serum

Q: How long does one tube of COSNORI Intensive Eyelash Serum last?
A: With twice-daily application to both lashes and brows, one tube typically lasts 6–8 weeks depending on the amount used per application.

Q: How long until I see results?
A: Most people notice their lashes looking healthier and fuller after 4–6 weeks of consistent morning and night use.

Q: Can I use this eyelash serum if I have lash extensions?
A: Yes, apply carefully to your natural lash line while avoiding the extension bonds—this can help keep your natural lashes conditioned underneath.

Q: Can I apply mascara after using this serum?
A: Yes, allow the serum to absorb completely before applying mascara or other eye makeup to prevent product mixing or flaking.

Q: Is this serum safe for sensitive eyes or contact lens wearers?
A: The formula includes soothing ingredients like centella and portulaca to calm the eye area, but if you have very sensitive eyes, do a patch test first and apply before inserting contacts.

Q: Who should avoid using this serum?
A: Avoid use if you're allergic to any listed ingredients, and discontinue if you experience irritation, redness, or swelling around the eye area.

Q: How should I store this product?
A: Store in a cool, dry place away from direct sunlight and make sure the cap is tightly closed to keep the formula fresh.

Cleanse your face thoroughly and ensure the eye area is completely dry and free of makeup or residue. Using the precision tip applicator, apply the serum directly along the upper lash line, painting from the inner to outer corner. Repeat on the lower lash line using the same technique. Switch to the brush applicator and apply evenly to the roots and underside of your eyebrows. Use any remaining product on the brush to coat the entire eyebrow area. Allow the serum to absorb fully before applying additional products or going to sleep.
