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
Hello to all skincare lovers! I just started using COSRX 6X peptide collagen tonic serum and I’m impressed! My skin feels much more hydrated from day one, something that doesn’t always happen with tonics. Niacinamide is a star ingredient for spots and pores, and it seems to be working wonders. In addition, hyaluronic acid gives a juicy and healthy glow to the skin. The texture is light and absorbs very quickly, perfect for use before moisturizer. Honestly, I highly recommend it! If you are looking for a product that gives you hydration, brightness and helps you with the appearance of pores, this is the right one.

Amazing skincare product
This stuff is amazing! It never makes me break out and my skin feels soft and moisturized. This is my second bottle. My skin looks great and I don’t even use any lotion afterwards.

A new staple!
Glowy, Firm, and Hydrated Skin – A New Staple!I’ve been using the COSRX peptide serum for several months now, and I’m honestly loving the results. My skin feels noticeably firmer, smoother, and more hydrated, especially in the mornings. It has a lightweight, watery texture that absorbs super fast and layers perfectly under my moisturizer.What I really appreciate is how gentle it is — no irritation or breakouts, even on my sensitive skin. My complexion looks brighter and more refreshed, and I’ve even seen a softening in some fine lines around my eyes and forehead.The bottle may look small, but a little goes a long way. If you’re looking for a boosting serum that actually does something, this is a great addition to your routine, especially if you’re focused on anti-aging or skin resilience.

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.

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!

Great for firming and restoring elasticity; skin feels lifted, smooth, and rejuvenated.
The COSRX 6X Peptide Collagen Booster Toner Serum is one of the best peptide products I’ve ever used! I already finished my first bottle and am now on my second. I noticed a big improvement in my sagging skin (caused by retinol use) — my skin feels firmer, smoother, and back to normal again.I highly recommend this serum to anyone who wants to bring back elasticity and a rejuvenated glow to their skin.

Lisa’s Reviews –
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!

C’est top ce produit! j’ai une peau tres reactive et asez sensible, mais Il me va tres bien comme base avant autres sérums/produits. Sa texture est tres leger et tu peux l’appliquer en plusieur couches. Ça booste l’hidratation j’aime beaucoup

Me cambió la vida. Ya no había manera de que el maquillaje me quedara bien y desde que lo uso mi piel se ve increíble.

This is an excellent product which works particularly well when teamed with PDRN in the am and after a Reedle shot in the PM. This will be a daily staple in my Korean skincare line-up. There are so many excellent ingredients just jam packed into this serum ( niacin amide hyaluronic acid, allantoin etc) I had to try it and my skin enjoys it and feels firmer.
