Powerhouse product for the cost
Wow. Years ago (I'm 52), in the mid-aughts when I started realizing I needed to care for my skin, quality products (outside Cera Ve) either required a prescription or were awfully expensive. You really had to pick and choose what you purchased, and it always came at a cost. Fast forward to now, and the product lines like COSRX , The Ordinary, the Inkey and more really have brought incredible skin care to an affordable price point. I was looking for a copper peptide serum that was a little less expensive than the one I was using ($40 for a .5 oz bottle). I saw this on special and decided to try it out, as I have liked some of their other products. I'm quite impressed after using for a little less than a week. One thing I think this does is really help distribute my other serums more evenly; in addition to copper peptides and nianamiacde in my regular rotation I use a growth factors serum, azelaic acid, and vitamin C, but I always feel like I have issues getting coverage. By starting with this, then layering the others, I find I get much better coverage. In general, just a few days in my skin is looking much more hydrated and even my fine lines and wrinkles are less prominent. (Its almost winter in Maine right now and hydration is a serious challenge.). The woman who put this on her lips - thank you! Genius. It really makes a difference. In addition to this, I find this product alone leaves my skin really smooth and hydrated under makeup. Its super lightweight and really helps achieve a good finish, and really lasts all day to boot. While Im a little old to achieve a "glass" finish I imagine a younger person could really nail that look with this.

Excellent Product For Sensitive Skin
Excellent product! This is a great product to use after cleansing your skin. My skin type is combination and very sensitive. I often breakout or get a rash from trying new products, but I did not with this. It is very gentle and works great for sensitive skin. My skin tends to get very dry during winter as I live in the north. This helped to keep my face more balanced and not as dry without it feeling sticky as some products feel. I use 1-2 pumps onto my fingertips and spread it evenly all over my face. I do another 1-2 pumps for my neck as well. This leaves my skin with a natural glow (not greasy looking). Make sure it fullly dries before applying your next step in your skin routine or applying makeup.

Effective and gentle on sensitive skin
I love peptides, as I find them effective and they don't typically irritate my super sensitive skin (rosacea, ezcema, etc). I've used various serums over the years, and decided to give this one a whirl. After my typical patch testing for several nights with no reaction, I began using it initially on my neck and chest, and eventually on my face, as well. After consistent use for several months, I saw a definite improvement in the texture and tone of my skin. I was happy to see some improvement in the laxity of the skin on my neck, which was thrilling. I use it under moisturizer, with a richer one for my drier neck skin. I have experienced no pilling, and my moisturizer absorbs well on top. I appreciate that it's cruelty free, and the large size makes it an exceptional value. I use it nightly over my entire face, neck, and chest, and the bottle lasts for months. This is a keeper for me.

LOVE this toner serum!
Love Cosrx - it's one of my go-to skincare brands and I am rarely disappointed. This 6x Peptide Collagen Booster Toner is one of my favorites and I have repeat ordered. But it does last a long time as a little goes a long way so I don't have to order it that often. It glides on beautifully and gives my skin such a nice glow. It's not greasy at all. It absorbs quickly. I like to order it on sale or on Prime day as I did this time but all of Cosrx's prices are reasonable, which makes this brand even better as the value is so great. This toner/serum is very hydrating. My skin loves it. I can get Rosacea redness and this doesn't irritate my skin at all--no redness, no itchy feeling, no irritated skin. Fragrance free. Just love it!

Nice serum but not a facial mist
This confuses me but it’s nice. I thought it was a facial Mist but it’s not. It has a squirt top which I love but it’s thicker like a like a phyto-mucin so it fits into the serum part of your routine. I like that it’s scent free for the most part and love how it helps my skin. I give it a 4 and not a 5 mostly bc I didn’t and still don’t entirely understand the product.

Obssesed. Fantastic benefits, amazing price.
One of my “hobbies” is trying skin care stuff and I have been on repeat recommending this to everyone! It is one of those rare products I have actually SEEN a difference in my skin. Not just “oh, maybe my skin is a little more hydrated” but actually getting complimented from people on how smooth and good it looks. Plus the price point is unbeatable. I see some improvement with fine lines, very brightening, mildly hydrating (not going to replace an actual lotion though), but where it really shines is calming any angry skin. If I see some redness cropping up or a pimple, this just calms it right down. Most of the time the pimple never even fully forms! But let me be transparent, I don’t suffer from severe acne- I just get the occasional, usually hormonal, pimple so I can’t speak to those dealing w cystic acne etc. I have recommended it a lot to my coworkers bc I’m in healthcare and a lot of us deal with “mask-ne”. It’s a good sized bottle, I’m barely halfway thru it after weeks and I use it everyday. No scent. Watery texture so it absorbs quickly, doesn’t interfere with my makeup. Honestly just blown away how well it works for a relatively inexpensive (especially in the skin care world) product. 10/10!

Ich habe das COSRX 6 Peptide Collagen Serum jetzt eine Weile verwendet und bin sehr zufrieden mit den Ergebnissen. Dieses Serum & Toner ist wirklich ein tolles Produkt, das meiner Haut zu einer sichtbar strafferen und elastischeren Textur verholfen hat. Hauterneuerung und Straffung: Das Serum enthält 6 Peptide, die nachweislich die Hautelastizität verbessern. Bereits nach wenigen Wochen der Anwendung konnte ich eine deutliche Verbesserung meiner Haut feststellen. Sie wirkt straffer und glatter, was für mich einen großen Unterschied gemacht hat, besonders im Bereich der Wangen und der Stirn. Beruhigende Pflege mit Niacinamid und Hyaluronsäure: Ich liebe, wie das Serum auch Niacinamid und Hyaluronsäure enthält, die meiner Haut zusätzlich eine beruhigende und feuchtigkeitsspendende Wirkung verleihen. Die Hyaluronsäure sorgt dafür, dass meine Haut den ganzen Tag über gut durchfeuchtet bleibt, während das Niacinamid hilft, den Hautton zu verbessern und eventuelle Rötungen zu minimieren. Es fühlt sich wirklich angenehm und erfrischend an, wenn ich es auftrage. Leichte Textur und schnelle Absorption: Die Textur des Serums ist leicht und zieht sehr schnell in die Haut ein, ohne klebrige Rückstände zu hinterlassen. Das macht es zu einem perfekten Produkt für die tägliche Hautpflege-Routine, da es gut mit anderen Produkten kombinierbar ist, ohne das Gefühl von Überladung oder Schwere. Beruhigender Hautpflege-Booster: Zusätzlich zur Straffung und Hauterneuerung hat das Produkt eine sehr beruhigende Wirkung. Besonders nach einem langen Tag oder bei Hautirritationen hat es meiner Haut Erleichterung verschafft und sie spürbar beruhigt. Fazit: Das COSRX 6 Peptide Collagen Serum ist eine hervorragende Wahl für alle, die nach einer effektiven Lösung für Hautstraffung und Hauterneuerung suchen. Die Kombination aus Peptiden, Niacinamid und Hyaluronsäure macht es zu einem besonders effektiven Pflege-Booster, der die Haut pflegt und gleichzeitig ihre Elastizität und Textur verbessert. Ich werde es definitiv weiterhin verwenden und kann es jedem empfehlen, der auf der Suche nach einer hochwertigen Korean Skincare-Pflege ist!

Love this product! After washing my face with cleanser and water, i pat my face dry, then use a layer or 2 of skin toner. Then I apply this serum. It rubs in nicely to your face. It leaves your face feeling fresh and adds a light glow. Sometimes I add another serum to the product, or if I'm in a rush I add moisturizer to the serum and apply both together. The glow will remain on your skin throughout the day. The glow is gentle. (and not to be mixed up with looking greasy or shiny from products that are too heavy or not rubbed into the skin properly) No stickiness noticed from this product, and it feels light and gentle on your face. It seems to have evened out my skin tone and my skin feels adequately hydrated after I use it. Initially i thought it was a little pricy for the product, but it is a large bottle and is lasting very well. I use 3 pumps worth each time I use it. So I would say it is priced fairly. My skin received several compliments when I wear this serum because of the gentle glow, plumpness and hydration factors. I have never worn a lot of make up throughout my life, but this serum could hopefully give you the confidence to also have a more natural look. I originally purchased because I noticed my skin seemed dryer - possibly due to the menopause. I am 56 years old, and would recommend this product for mature skin.

j'adore ce produit, c'est devenu un incontournable. Sans parfum, sans actif irritant pour ma peau très sensible et réactive. La texture est très fluide presque comme un eau mais s'applique très bien. Ne peluche avec aucun autre produit grâce à sa faible viscosité. C'est le premier sérum que j'applique après avoir nettoyé mon visage. Elle ne m'a causé aucun bouton, pas d'effet de rebond. Ma peau est de meilleure qualité depuis que je l'utilise. La quantité est grande, très bon rapport qualité/prix. Je l'utilise depuis des mois.
