COSNORI Long Active Eyelash Serum - Vegan Lash & Brow Booster, 0.3 fl.oz. with Peptides & Hyaluronic Acid for Stronger, Thicker La

This Korean award-winning serum combines a patented peptide complex with moisture-binding hyaluronic acid and soothing botanicals to deliver targeted nourishment to lash shafts and roots. Designed for daily use, the water-based formula matches the eye's natural pH and avoids oils, helping minimize irritation while supporting thicker, healthier-looking lashes and brows over consistent application.

How quickly will I notice changes in my lashes?

Many users report subtle improvements in lash strength and appearance within a few weeks of regular application, while fuller-looking lashes may take consistent use over several cycles. Results depend on individual lash growth rates, but the serum is formulated to support both immediate conditioning and longer-term resilience.

• Visible conditioning in about 2–4 weeks for many users
• Stronger, less brittle lashes with ongoing use
• Designed for daily nighttime or morning routines

How do I apply the serum for best results?

The bottle features a dual applicator: a wand similar to a mascara brush to comb product along the lash line and a ball-tip for precise root application between lashes. Apply a thin line along the upper lash base and use the ball tip for focused root placement; no need to rub or overdose.

• Use the wand to distribute serum from root to tip
• Use the ball-tip to place product directly at lash roots
• Apply once daily to clean, makeup-free lashes and brows

Is this safe for sensitive eyes and eyelash extensions?

The formula is water-based, oil-free, and pH-balanced to match tears, which reduces the chance of stinging or irritation. It has undergone irritation testing and is formulated without prostaglandins, making it suitable for many sensitive users and compatible with extensions when used as directed.

• Water-based, oil-free texture to minimize residue
• pH-aligned to reduce eye discomfort
• Tested for skin irritation and formulated for gentle daily care

What active ingredients make this effective?

COSNORI’s patented peptide blend works with hyaluronic acid and healing botanicals to add elasticity, lock in moisture, and supply nutrients that support healthier lash and brow condition. These components aim to reduce breakage and help lashes appear fuller and shinier when used consistently.

• Patented peptide complex for elasticity and resilience
• Hyaluronic acid to retain moisture and smooth shafts
• Centella asiatica and other extracts for calming nutrition

Who is this for? COSNORI Long Active Eyelash Serum is ideal for anyone seeking a gentle, non-irritating lash and brow treatment—people with sensitive eyes, wearers of lash extensions, vegans, and users who want a prostaglandin-free alternative. If you want a daily, easy-to-use serum to condition, protect, and visibly improve the look and feel of lashes and brows over time, this product fits into most beauty routines without heavy oils or strong actives.
