COSNORI Long Active Eyelash Serum 0.3 fl oz — Peptide & Hyaluronic Lash Strengthener

COSNORI Long Active Eyelash Serum is a gentle, peptide-boosted daily serum designed to support visibly fuller, stronger lashes and brows without prostaglandins or irritating oils.

This lightweight, water-based formula blends a patented peptide complex with hyaluronic acid and plant extracts to help nourish lash fibers and the skin at the lash line. Developed in Korea and recognized by consumers and retailers, the serum pairs a dual-tip applicator so you can sweep through lashes like mascara and target roots precisely. It’s hypoallergenic, oil-free, and formulated at a tear-like pH to reduce discomfort—suitable for routine use and compatible with extensions.

How should I apply this serum for reliable daily results?

Apply once daily, ideally at night, to clean, makeup-free lashes and brows. Use the wand to comb from root to tip, then switch to the ball-tip end to deposit product directly at the lash line for targeted nutrition.

• Cleanse face and remove eye makeup first.
• Use wand to coat lash lengths, then ball tip between base of lashes.
• Allow to dry before sleeping or applying other products.
• Consistent nightly use yields best results; small weekly visible changes can appear in about two weeks.

What active ingredients are in the formula and what do they do?

The serum centers on a patented peptide blend plus hyaluronic acid, supported by botanical extracts to maintain moisture and resilience. These components aim to strengthen the lash shaft, preserve flexibility, and support the skin around the follicles without harsh actives.

• Patented peptide complex: helps improve elasticity and shaft integrity.
• Hyaluronic acid: hydrates and helps lashes appear smoother and shinier.
• Centella asiatica extract: soothes and provides additional nourishment.
• Water-based, oil-free carrier: reduces heavy residue and irritation risk.

Is this safe for sensitive eyes and compatible with extensions?

The formulation is designed to be gentle: oil-free, matched to the pH of tears, and hypoallergenic-tested to lower the chance of stinging or redness. Because it avoids oils and harsh prostaglandin analogs, it’s suitable for many people who wear lash extensions or have sensitive eyes, though individual reactions vary.

• No prostaglandins or irritating oils included.
• Water-based and tear-like pH for comfort.
• Passed skin irritation testing; still patch-test if you have extreme sensitivity.
• Safe to use after extensions when dried fully—follow technician advice.

When can I expect to notice changes, and how long will they last?

Some users observe improvements in lash strength and appearance in as little as two weeks, with fuller-looking lashes developing over consistent weeks of use. Long-term maintenance depends on continuing the product; stopping use will gradually return lashes to their baseline over time.

• Initial improvements: often within 2 weeks for many users.
• More noticeable fullness and resilience: after several weeks of nightly use.
• For sustained effects: incorporate into nightly routine indefinitely.
• Results vary by individual factors like lash cycle and lifestyle.

Who is this for? COSNORI Long Active Eyelash Serum is aimed at anyone seeking a non-irritating, vegan-friendly option to support longer-looking lashes and fuller brows—especially people who prefer water-based care, wear extensions, or want a gentle nightly regimen that targets lash roots and lengths. It’s a practical choice for sensitive eyes and for those who favor proven Korean beauty formulations with consumer recognition.
