COSNORI Intensive Eyelash Serum - Korean Eyelash Root Care Serum for Healthier and Stronger Lashes - High Purity Protein, Plant-Based Collagen - Hypoallergenic Formula, Non-Irritating, 0.2 fl.oz

Used it every night for a week so far and I think it works! I see new lashes coming out! I love the brush too bc it’s wider than other lash serum brushes so you can put more product on your lash line!

Didn’t see too much of a difference with consistent use

Lashes are getting longer and stronger

It is easy to use and does not burn my eye. I only used a week so I don't know the result yet.

I'm usually so cautious about putting anything near my eyes - they're sensitive and I've always worried about irritation or long-term damage from lash serums. But after doing some research, I felt comfortable trying this and I'm honestly so glad I did! What really convinced me is that the serum is designed to mimic the composition of healthy human tears, which made me feel way more confident about using it regularly. It's made with plant-based collagen, high-purity protein, and hypoallergenic formula, and I've experienced ZERO irritation. No burning, no redness, nothing. It feels so light and hydrating when I apply it!! I've been using it consistently for a week now and I feel like my lashes feel stronger, shinier, and less prove to falling out. They look healthier overall, and I love how the precision brush makes application easy and clean. This product has really earned my trust and that says a lot because I've avoided lash products all my life!! If you've been nerous to try one, especially with sensitive eyes, this is one to go for!!

Worst eyelash serum I've ever used! Caused my eyes to BURN and turn SOOO red after the first use. I've used Cosnori products before n never had a reaction like this. I had to go to the ER and get prescription eye drops. They stayed like that for over 2weeks and burned the entire time. I'd never recommend this product!! Buyer beware...

I’ve only been using this eyelash serum for a little over a week, so I can’t fully speak to its long-term effectiveness, but so far, I’m enjoying it. The formula is very watery, which makes it super easy to apply especially with the applicator. It's been an easy addition to my nightly routine. I really liked the ingredients list, and that's what initially drew me to this product (and the fact that it's a brand I've purchased from and enjoyed in the past). It includes vegan collagen and biotin, which, I'm so glad it's vegan collagen since I personally prefer it. There’s also panthenol, which I love seeing in my skincare and I know my skin already loves as a hydrator. It'll hopefully help condition the lashes and keep them soft and hydrated similarly. Copper tripeptide-1 and myristoyl pentapeptide-17 are also notable—they’re peptides that are often used in lash serums to help stimulate the lash follicle. I do wish these were higher up in the ingredient list but I'm still happy they're there. Other notable ingredients are Centella Asiatica (which I like for its calming effects) and sodium hyaluronate (a form of hyaluronic acid). I also like that the product hasn’t caused any irritation or stinging. I couldn’t find the ingredients in English on the box, just Korean. The ingredients list, according to Yesstyle, is as follows: Water, Pentylene Glycol, Butylene Glycol, 1,2-Hexanediol, Hydroxyethylcellulose, Propanediol, Sodium Polyacryloyldimethyl Taurate, Ethylhexylglycerin, Disodium EDTA, Portulaca Oleracea Extract, Houttuynia Cordata Extract, Centella Asiatica Extract, Sodium Hyaluronate, Tromethamine, Polysorbate 60, Disodium Phosphate, Sodium Phosphate, Tocopherol, Biotin, Panthenol, Glycerin, Collagen, Glycoproteins, Leuconostoc/Radish Root Ferment Filtrate, Oligopeptide-2, Hydroxyacetophenone, Caprylyl Glycol, Copper Tripeptide-1, Sodium Benzoate, Benzoic Acid, Myristoyl Pentapeptide-17.

I haven’t seen any results, maybe I need to be more consistent with it. It doesn’t irritate my sensitive eyes so that’s a plus.
