COSNORI Long Active Eyelash Serum - Korean Eyelash Boost Serum - Eyebrow Growth Enhancer for Longer and Thicker - Vegan Prostaglandin Free & Non Irritating - Peptides, Hyaluronic Acid, 0.3 fl.oz.

I’ve been using the COSNORI Long Active Eyelash Serum for a few weeks now and I really like it! My lashes look noticeably longer, thicker, and healthier, and I love that it doubles as an eyebrow enhancer too. It applies so easily with the fine brush tip, dries quickly, and doesn’t leave any sticky residue. What really sets this serum apart is how gentle and non-irritating it is. My eyes are usually very sensitive, but I’ve had zero issues—no redness, itching, or burning. The fact that it’s vegan, prostaglandin-free, and packed with nourishing ingredients like peptides and hyaluronic acid gives me so much peace of mind. I also appreciate that the formula feels lightweight but still hydrating, so my lashes don’t feel brittle. With consistent use, I can already skip mascara some days because my lashes look naturally fuller. If you’re looking for a safe, effective, and clean lash and brow growth serum, this one is definitely worth it.

All I can say is wow. I never thought my lashes were capable of getting longer & thicker. I have naturally short, fine and straight lashes (Asian lashes) & relied heavily on lash clusters for a while. I bought this product in May 2026 & have used it *almost* consistently. I take a few days to a week break sometimes since my eyes get itchy with allergies. Already in the first month of use I noticed a drastic difference in my lashes. This is the first serum I’ve ever used so I can’t compare to other brands but I’ve had no issues. I also use it on my brows which have helped with a lot of the bald spots there as well. I can’t recommend this product enough. Will definitely be a consistent repurchase for me.

I have been using COSNORI Long Active Eyelash Serum since May 12. I can see my lashes looking a bit longer and healthier over time. The dual applicator makes it easy to apply along the lash line and on the lashes, and it feels gentle during use. The formula is lightweight and not greasy, and it has not caused much irritation when used carefully. It also seems to help reduce lash shedding and improve overall strength over time. The only downside is that applying too much can sometimes leave a slight white residue, and it may cause mild stinging if it gets into the eyes. Results take time and require consistent daily use. Overall it is a solid lash and brow serum that shows gradual improvement and is worth using if you stay consistent.

This works!!! I somehow lost a ton of lashes on my right side and have been using this at night, and as a primer during the day before mascara. My lashes have gotten SO much longer. I wish I had taken a before pic.

I bought this thinking that I wouldn’t get dark discoloration under my eyes like the other one I got from the doctor offices. One review said her eyes didn’t get the dark eyes well I used it 5 days and it is now dark under my eyes… I hope it goes away like the other brand. It may make the lashes grow but you’ll get the dark circle under the eyes

I've tried almost every lash serum on the market, and this one is by far THE BEST. Trust me and give it a try, it will save you time and money. The most important thing for me was that it didn't cause dark circles. I previously used another product that showed quick results increasing the length of my lashes but within two weeks I developed severe pigmentation under my eyes, which took a lot of effort to recover from. Since then, I always check the ingredients of products im going to use around my eyes, especiallylash serums. This one doesn't have any ingredients that cause dark circles or have any harmful substances, and I didn't experience any irritation or burning from this product unlike others I have tried. Even if you don't have sensitive eyes like me, it's better safe then sorry when putting something so close to your eyes. And it really works. Honestly, with other lash serums, I never saw noticeable improvements. But after using this for about a month, my lashes became visibly thicker and fuller. The results weren't immediate, but from my experience, quick results often mean stronger chemicals which is what was causing the dark circles and irration I think. I prefer the gradual improvement this product delivers. After applying it like part of my nightly skincare routine for 3-4 weeks, my lashes now hold a curl beautifully, even when in wake ip in the morning. And my lashes don't fall out even when I use an eyelash curler, so I'm extremely satisfied!

i'm seeing on reviews that this serum doesn't sting or irritate peoples eyes -- this doesn't irritate my eyes or i would dispose this immediately. But when i accidentally get it into my eyes it stings and hurts A LOT. been using this for almost 2 months now and i don't see dramatic results. however i do notice some volume/new lashes on my top/bottom. i also brush it thru my brows and i see a difference. Hygiene and safety is everything for the eyes, people! i would always only use this serum on clean eyes and dispose this after 2 months...8 weeks is a long time..and you don't want to risk unwanted bacteria into your eyes just to possibly have a stye or infection. OVERALL this is a GREAT lash serum because it nourishes the lashes, doesn't give your under eyes a reddish look, and sold at a decent price.

The applicator brush broke after using it only twice. I liked the product but didn’t get to use it long enough to see if it had good results

Lo utilizzo da pochissimo però non dà problemi agli occhi e le ciglia (reduci da lash cocaine) stanno restando abbastanza folte

LOVE THIS! I’ve been using it for a month and have seen so much growth on my eyelashes and eyebrows. So far it’s given me so much more volume, the number of lashes I have doubled however I haven’t seen much of a difference in length yet but I think I have to wait longer. My sister used this before me and has noticed a big difference in volume and in length. This is also the first eyelash serum that has given me no redness or rash, I have really sensitive eyes and grandelash and babelash although they did make my eyelashes longer (not more eyelashes though) were really irritating me, they made me look like a panda with red eye bags that itched. ANYWAYS off topic but this is such a great product and crazy cheap in comparison!!!

Ich verwende das Serum morgens und abends seit Beginn des Jahres und habe ziemlich schnell den Wachstum der Wimpern gesehen. Nach Jahre langem Tragen von Wimperverlängerungen hätte ich nie gedacht das ich mal so zufrieden mit meinen eigenen Wimpern sein werde. Hab mir in Korea das Serum gleich nachgekauft und auch dort ist es einer der am besten verkauften Produkte! :) Natürlich ist es wichtig das Produkt regelmäßig und für einen Zeitraum anzuwenden - dafür wird man aber auch belohnt :D

You need to apply everyday for better results obviously. I love the product and I can see regulars writhing a month

De todos los productos para pestañas que he utilizado creo que es mi favorito hasta ahora. La presentación en la que viene para aplicar es muy cómoda, antes me daba más flojera con los otros y sentía que era más sucio pero con este aplicador no hay ningún problema. A los resultados de pestañas si noto la diferencia. Yo tengo pestañas largas pero busco tener volumen y que estés más fuertes. Siento que se me dejaron de caer tanto y si he notado que en zonas donde no tenía ya tengo más. Además de que si son más largas, no crecen mucho más eso si, si tienes pestañas pequeñas no se que tanto pueda ser el cambio pero a mi me funcionó muy bien
