    • Great product at a great price
Size: 5.07 Fl Oz (Pack of 1)
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! ... show more

    • Fantastic Peptide Serum - A Game Changer for My Skin!
Size: 5.07 Fl Oz (Pack of 1)
After being disappointed with TO’s “Buffet” serum and not seeing any results from other peptide creams (or collagen supplements/powders) and becoming a newfound fan of many of the products sold by COS RX, I decided to add their peptide serum to my skincare routine. I am absolutely thrilled with the results! From the first application, my skin felt noticeably smoother, plumper, and more hydrated, with results appearing very quickly. The serum absorbs quickly without leaving any sticky residue (it’s not like the snail products), making it perfect for layering under my serums and moisturizer. After just a few DAYS of consistent use, I've noticed a significant improvement in the texture and firmness of my skin. Fine lines appear diminished, and my complexion looks more radiant and youthful. I love that it doesn’t have any fragrance or harsh chemicals, making it suitable for my sensitive skin. Despite having rosacea and being acne-prone with sensitive skin, this product does not make my skin react angrily, which is a huge relief. It pairs great with the COS RX Essence. It’s not moisturizing enough to use on its own for my dry skin, but it doesn’t claim to be. One point of confusion is the suggestion to replace this with your toner. To me they serve two different purposes. Personally, I use it after my toner/exfoliator or throughout the day for an extra boost of hydration since it’s so lightweight, and it works wonderfully for me. I don’t wear makeup so I can’t speak to how well it is under makeup, although it’s water-like consistency leads me to believe it won’t affect makeup. It doesn’t pill when layering other skincare products. The packaging is also a plus—it's sleek and features a hygienic pump that dispenses the perfect amount of product every time. A little goes a long way, so I feel like I'm getting great value for my money. Overall, this peptide serum has exceeded my expectations, and I couldn't be happier with the results. I highly recommend it to anyone looking to enhance their skincare routine and achieve glowing, healthy skin. This product is definitely a staple in my beauty regimen now! ... show more

    • Less for more
Size: 5.07 Fl Oz (Pack of 1)
COSRX snail ingredients are my to go! the COSRX Ex Peptide Collagen Booster Toner Serum, and I’m blown away! The mix of niacinamid and hyaluronic acid has worked wonders for my skin. It’s made my skin feel smoother and more hydrated. I use it every day, and my skin looks plumper and more youthful. It absorbs quickly without leaving any sticky residue, which is great for under makeup. The scent is refreshing but not too strong. I highly recommend it to anyone looking to take their skincare routine to the next level! ... show more

    • Plump it up!
Size: 5.07 Fl Oz (Pack of 1)
Great consistency, great plumping action. Pores are less visible, under eye skin looks fuller. The volume of product for the money is kinda crazy. I am used to paying way more for way less. I have not used it WITH retinol and I have read not to do copper with retinol products so maybe steer away from that, but it has worked with all my other serums and creams. Definitely worth a try and definitely worth the hype. ... show more

    • Not bad
Size: 5.07 Fl Oz (Pack of 1)
It does not make your skin feel anything like Tatcha's Dewy Serum does, but this is much less expensive. It does seem to work well with any moisturizer you put over it. Does leave your skin soft and not greasy.

    • Glass skin vibes
Size: 5.07 Fl Oz (Pack of 1)
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. ... show more

    • Incredible, long-lasting hydration for very dry, sensitive skin

This serum has been a game changer for me! I'm really happy I decided to buy it because it provides amazing hydration that lasts, even for my super dry and sensitive skin. My skin feels so much more supple now! It's definitely a product I would recommend, and I’ll be stocking up since it actually meets my expectations! ... show more

    • Good for sensitive/oily skin
Size: 5.07 Fl Oz (Pack of 1)
I have extremely oily skin and all the products I have used in the past that were meant to control oil have not worked for me. What I love about this serum is that the texture is very light, almost like water, but when I apply it, my skin feels plump and moisturized. I only need a small amount and can wear it under makeup. Other serums feel heavy and sticky on my face, which makes me oilier and usually causes breakouts. I've only been using COSRX for a couple months, but it seems like it's repairing my skin barrier and helping my face look less dull. ... show more
