Glowy 2nd step of my skin care
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.

Brilliant multi peptide giving great results
An amazing serum full of various peptites including copper peptides. It's quite a watery consistency but this doesn't stop it being a great product. The amount you get is great and it's easy to use on your face and chest. It's made my skin softer and reduced fine lines slightly. Skin appears more glowy. Skin texture is also better. I used this before applying vitamin c and niacinamide serum, it all absorbed really well.

great product
At first it appeared watery, yet using it leaves a nice tightening to the skin and small imperfections are fading rapidly. Doesn't take a lot of it as it is very thin and like water in the hand. Pleased so far after the very first use noticed a marked difference! P.S. it is my wife who wrote the review and uses the product just to be clear :)

COSRX The 6 Peptide Skin Booster Serum is a lightweight, fast-absorbing serum with 6 peptides, niacinamide, and hyaluronic acid. It deeply hydrates, smooths the skin, and improves overall texture without feeling sticky or heavy. With regular use, skin looks more plump, fresh, and healthy, with a subtle anti-aging effect over time. Great for layering under moisturizer or makeup and suitable for most skin types.

Works like a dream for my skin
Absolutely love this as a first layer serum, it contains HA so you can skip that and go straight for this, full of skin loving peptides, so light on the skin, large bottle but lasts absolutely ages, absorbs very fast due to it being watery but this is good as you can then layer thicker serums on top. I’ve spent a fortune on skincare products now I’m 49 and really need to look after my skin now. When you are young a good moisturiser is all that’s needed and possibly this as a first step but as you get older your skin needs more attention and this product ticks all the right boxes. It’s expensive but lasts a long time so if you break it down it’s great value for money. I would love if they added matraxyl into this serum/toner as I’m having to use a separate serum for that afterwards. I’m going to start pairing this with snail mucin and see if it makes a difference but been using a good while now and I can definitely see results, my skin is hydrated and more even tone and looking plumper. With skincare try just adding one new product at a time so you can see the real results. That’s what I did with this product and the results are amazing and worth every penny. Don’t be put off by the watery consistency it just means it absorbs faster. You also don’t need a lot 2 pumps is more than enough (sometimes we see a big bottle and think we need to use a lot but really you don’t. I’ve been using a good while now and there’s still loads left!!! Definitely recommend especially for mature skin. I have sensitive skin and have had no issues whatsoever. It’s one of my go to products now.

Great serum for great results.
Bought this because I had other items from the same line and it’s great. It leaves my skin feeling soft, and if you are someone who used things like retinol it really does help then absorb. I’m in my mid 50s and I’m a complete convert. Moisturiser applied on top also seems to absorb better and, on the rare occasions I actually put makeup on, it sits really well and doesn’t slide or crease. This makes me feel like my skin looks fresher and plumper and my fine lines are gone. Even my 1 deeper forehead crease is barely noticeable. It also causes no irritation.

Wish it worked for me, but…
Nice looking bottle, the product is temporarily hydrating and has a nice feel and appearance. But my skin has broken out pretty badly, and just a word of warning: peptides are not supposed to cause purging. So sadly I won’t be using or buying this again.

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!

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.

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.
