COSRX 6X Peptide Collagen Booster Toner Serum with Copper Peptides, Niacinamide & Hyaluronic Acid Skin Renewal Boosting Facial Essence for All Skin Types, Korean Skin Care, 5.07 Fl.Oz

This booster serum is a powerhouse. It feels like a professional skincare treatment in a bottle. The formula is incredibly lightweight, almost watery, but it delivers intense hydration and firmness. My skin feels bouncy, smooth, and refreshed immediately after application. After consistent use, I noticed improved texture and a subtle tightening effect — especially around my cheeks and jawline. It layers perfectly with other products and never pills. The combination of peptides and niacinamide makes my skin look brighter and more even. This is one of those products that quietly upgrades your entire routine. It’s gentle, effective, and suitable for daily use. If you want that glass-skin glow, this is a must-have.

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! 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.

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!

Good product great value, nourishes the skin before applying your makeup. Very light and it doesn’t have any smell.

This COSRX 6X Peptide Collagen Booster Toner Serum has become an absolute MUST in my nighttime routine. It’s the very first thing I put on my face, and the difference it makes is incredible. The texture is silky and lightweight, but still feels nourishing and powerful. My skin drinks it up instantly! The copper peptides, niacinamide, and hyaluronic acid work so well together, my skin looks smoother, more hydrated, and noticeably firmer. I wake up with that fresh, plump, revived look every time. It layers perfectly with the rest of my skincare and never causes irritation. This is hands down one of my favorite Korean skincare products ever. If you want a toner-serum that truly boosts your routine, this is it. Perfect gift and perfect stocking stuffer. I’ll be repurchasing again and again!

It's the 3d week of using this fot me. I noticed that my skin became calmer, nicer, glowing and more hydrated after 2 weeks. Now I have added the ordinary niacinamide & retinol to my routine. Using this peptide serum before niacinamide day and night, worked super for me. Will buy more.

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!
