COSNORIIntensive 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

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 will need to use this for a longer time to see it's effects, but so far it doesn't irritate my eyes and I appreciate that it doesn't have prostaglandins so I don't lose any of my aegyo-sal (something I've had issues with other lash serums). The packaging is sleek and pretty and the brush tip makes it easy to apply to your lashline.

I have really been liking this lash serum. I tried this one on a whim and I am really glad I did.I do have naturally longer lashes, but they are, in my opinion, sparse and prone to falling out, no matter how gentle I am when removing makeup. In the past few years, they also seem a bit brittle and/or dry. Lash serums do help, but without fail, the ones I've tried always cause me to wake up with puffy and irritated eyes. This one has not caused any puffiness or stinging! My lashes already seem more conditioned, and since I've had no negative reaction, I can keep using it long-term.I'm pretty sure that this lash serum works so well for me for three main reasons. First of all, no matter how hard I try, I cannot detect any fragrance or odor; I don't have to use 100% fragrance-free makeup or skincare, but have learned to always avoid it for anything going so near my eyes. Secondly, the little applicator brush is very fine for precision application, and is not a weak/floppy little brush; it is really easy for me to direct the serum exactly where I want it to go and nowhere else. The brush comes out of the tube lightly coated, not saturated or drippy. Finally, the serumitself seems to have just enough texture to stay where I put it at my lash line instead of creeping into my actual eye--a problem I've had with serums in the past.I have added this one to my saved cart to order again!

The applicator is precise, the serum is clear and scent-free, and it dries quickly. It contains D-Panthenol, Biotin, and hyaluronic acid—ingredients that support lash health. But the directions and ingredient list are only in Korean, which makes me hesitant to keep using it near my eyes without knowing exactly what’s in it or how often to apply it.

I am very pleased with the quality and performance of this eye lash serum. I have been using it on my lashes for 2 weeks now every night before I go to bed. My eyes are often sensitive to products, but I have had no adverse issues with this serum at all. It is easy to apply. I find that there is enough on the brush to saturate both my upper and lower lash lines in just one swipe. I just rub it in gently with my fingertip. This makes me feel that this product will last me a good long while, making it a very good value. I love that it is made in Korea. I am a fan of Korean makeup and skin care.My lashes seem to be improving and getting denser the more I use this, and it has only been a short time. I am looking forward to the progress as I continue to use it. I'm off to a great start. I recommend this lash serum.

MY ⭐️RATINGS:4⭐️- I would recommend it as the one to get.20250425Like with any serum I use, consistency and patience are key to achieving results. I apply this daily as recommended, and I’m hopeful I’ll start seeing results soon.I apply this serum to my upper and lower eyelashes, starting with the upper ones, as if I were applying eyeliner. I do this at night because I prefer to keep my face clean without makeup.I’ve had success with other eyelash serums, so I’m optimistic that this one will yield the same results.EXPIRATION DATE: 07/25/2027I always check for an expiration date before using, ESPECIALLY with health & beauty products.This Eye Lash Serum is PRICED in the usual range.

I haven't used this long enough yet to tell if it actually works but I can confirm that I have not had any weird reactions at all. My eyelashes are short and thin, and I am excited to see if this helps them grow in fuller and longer. I generally have great experiences with Korean skincare, which this is. The container is the size of a mascara and cute. The applicator is a thin brush that you sweep over your eyelid. Easy and quick to use!
