Title: Great for my dry, sensitive skin!
Review: LOVE this product! I have dry, sensitive skin and this is such a nice toner to use before the rest of my skincare. I keep thing minimal so as not to irritate my skin and this set a nice, calming base after I wash my face. A lot of times I will just use this and then moisturizer and be done. My skin looks more hydrated and moisturized with this product. Highly recommend!

Title: Great product at a great price
Review: I absolutely love the COSRX 6X Peptide Collagen Booster Toner Serum! It has quickly become a staple in my skincare routine. This product delivers on all its promises and more.First and foremost, the plumping effect is incredible. My skin feels noticeably firmer and smoother, giving it a youthful, radiant glow. The hydration it provides is top-notch—my skin stays moisturized all day without feeling heavy or greasy. It layers beautifully under makeup and other skincare products, making it versatile for both day and night use.On top of all that, the price is fantastic for the quality you’re getting. It’s rare to find a product this effective without breaking the bank.Overall, I can’t recommend the COSRX 6X Peptide Collagen Booster Toner Serum enough. It’s a game-changer, and I’ll definitely be repurchasing!

Title: This is a great peptide serum.
Review: It soaks right in and doesn’t feel tacky. It compares to the timeless synthe 6 serum and the advanced clinicals peptide serum. It has zero scent and a water like texture.

Title: Yes I like this
Review: I found this product to work well and saw results within a few days. I take very good care of my skin and use multiple products but this one seemed to do a good job of prepping my skin. No irritation and no residue.

Title: Glass skin vibes
Review: Saw someone on Instagram use it and she’s not very salesy, so I jumped on it as a replacement for snail mucin. Truly amazing. Gives that soft glow, like a full glass skin moment every time. Skin feels plumped up and soft. Apparently it helps the next serums you apply work better, too! Idk about that, but whatever it’s doing for my skin is great. The bottle is pretty large, too, and the packaging says you can layer it more for additional hydration…I did that tonight after steaming my face after a clay mask and I’m even more thrilled. It’s pretty excited to look in the mirror and think, “wow, pretty!” when it comes to your skin. And this definitely makes me think that, more and more as I use it.

Review: This toner-serum hybrid has quickly become my skincare MVP. It’s lightweight, absorbs fast, and leaves my skin feeling instantly plump and hydrated. The combination of peptides, niacinamide, and hyaluronic acid is like a triple-threat for smooth, glowing skin.After just a week, I noticed my skin looking brighter and more even. It layers beautifully under other products without feeling sticky, which is a huge plus. And it’s gentle enough for daily use, even on days when my skin feels a bit sensitive.If I had to point out a downside, the bottle isn’t travel-friendly—it’s a bit bulky, so decanting is a must for trips. Also, the hydration is amazing, but if you’re looking for heavy-duty anti-aging, you might need to pair it with a richer cream.Overall, it’s a fantastic product for anyone wanting that fresh, dewy look without the fuss. Perfect for beginners or skincare addicts alike!4.8/5

Review: 😍Wow , ich bin sowas von begeistert von diese Marke Cosrx . Am Anfang habe ich mir Retinol creme bestellt um es auszuprobieren ,und direkt nach paar anwendungen meine Haut ist sooo glatt geworden . Da ich kleine Pickelchen hatte und hab alles mögliche ausprobiert , sogar zu collagen tabletten gegriffen , aber es hat mir nichts gebracht . Aber seit dem ich Cosrx retinol hab , meine Haut ist perfekt geworden . Deswegen ich habe mir direkt komplette set pflege produkte gekauft im wert von 350 eur 😂. Ich weis das es verrückt klingt , aber diese pflegeprodukte sind einfach WELTKLASSE 👀👍👍👍💘!!! Wo ich Niaciamid , Serum , Gel , Toner , Ampulen , Augencreme , Pads , Creme mit Schnecken schleim und Propolis ausprobiert habe von Cosrx , war ich mehr als begeistert .Ich bin soooo glücklich jetzt . Ich bin 37 aber viele denken ich wäre 20 ))Meine haut ist so am glänzen , soo glatt und die Poren sind soo klein geworden , ich habe keine Flecken , mein hautton ist gleichmässig geworden . Es hinterlässt kein Film , es klebt nicht , und sehr angenehm auf der Haut . Meine Haut ist sehr gut mit Feuchtigkeit versorgt .Unglaublich einfach . Ich dachte ich werde NIE so gute kosmetik bekommen für angeneme Preis . Und diese Geld was ich ausgegeben habe hat mir nicht leid getan . Sondern diese Qualität jeden Euro wert .Ich habe direkt es meine Mama und Freundin empfolen 😁. Mädels ,wenn ihr noch am zweifeln seid , denn kauft es euch ohne zu überlegen . Glaubt es mir , wenn ihr diese Marke auspribiert , egal welche Produkt , seit dem es wird eure lieblings pflege sein. Ich schwöre es euch !!! Das ist das beste was ich mir seit letzte zeit gekauft habe . Einfach nur 💥WOW 💥 Ich bin verliebt in alle Produkte von diese Marke .
