  • 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. ... show more

  • Great value and delivers results
Just can't beat COSRX. Always priced great and does the job. Gentle on my skin. No real scent or at least not overpowering. Not sticky when you let it absorb into your skin. Keeps my skin moist and glowing alone or under makeup. Not sure if does anything to minimize pore size but definitely doesn't clog my pores. Love this Korean skincare line ❤️ ... show more

  • Great value for lightweight peptide serum
This product has become an immediate repurchase. The value of the product is great, and it was a great addition to my routine. This product is very lightweight and absorbs easily. It feels like a very thin hydrating product and smooths effortlessly across the skin. There is no fragrance that I have noticed, and this does not leave me with any kind of a sticky reside. This is a great serum for someone wanting to add peptides to their routine but without the weight of a heavy serum. This is not the only peptide product I use so i cannot speak much to it in that sense, but I enjoy it enough to continue using it and repurchasing it for the experience. ... show more

  • The best peptide serum
This incredible serum contains peptides (including Argireline and Matrixyl/called Botox in a bottle). It is firming, soothing, hydrating and refreshing. My skin is plump, soft, smooth and youthful. It is fragrance free, has a liquidity consistency, but it is not sticky or oily. I apply 2 layers on in my PM ritual. I highly recommend this product. ... show more

  • Great Hydrating and Firming Toner Serum!
I’ve been using the COSRX Serum for a few weeks now, and I really like how lightweight yet nourishing it feels on my skin. The formula absorbs quickly without leaving any stickiness, and it gives my skin an instant boost of hydration and plumpness. I’ve noticed my skin looks smoother and more refreshed, and the peptides seem to help with firmness over time. The bottle is generous in size, which makes it a good value, and it layers well under my other skincare products without pilling. My only small complaint is that it takes a little time to see visible results with collagen and peptides, so it’s more of a long-term investment in your skin rather than an instant fix. Overall, it’s a great product if you’re looking for a hydrating and skin-strengthening step in your routine. ... show more

  • Another COSRX Winner: Lightweight Formula with Big Results
The COSRX 6X Peptide Collagen Booster Toner Serum has become another standout addition to my daily skincare routine, proving once again why COSRX consistently delivers quality products. I use this as part of a complete COSRX regimen alongside their Advanced Snail Mucin Gel Cleanser and Snail Mucin 96% Power Repairing Essence, and the synergy between these products has resulted in marked improvements in both skin smoothness and hydration levels. What I particularly appreciate about this toner serum is its lightweight, non-sticky formula that absorbs quickly without leaving any greasy residue, making it perfect for layering with other products. The concentrated formula means you only need a small amount per application, which makes this product exceptionally economical and provides excellent value for money. It's become an indispensable part of my skincare routine that seamlessly integrates with other COSRX products for comprehensive skin improvement. Pros: Excellent addition to a complete COSRX skincare routine with proven synergy Delivers noticeable improvements in skin smoothness and hydration Lightweight, non-sticky formula that layers well with other products Quick-drying without greasy or heavy residue Concentrated formula - a little goes a long way for exceptional value Seamlessly integrates into daily skincare regimen Cost-effective due to small amount needed per application Consistent quality from trusted COSRX brand Cons: Haven't found any significant drawbacks ... show more

  • Peptides
Nice light toner that's to be used as the first step after washing. Lightly moisturizes and tones. Full of good peptides to improve skin tone. Sinks in completely, fragrance free, non sticky. Leaves my sensitive aging skin with a nice glow.

  • Hydrating, Smoothing, and So Easy to Use
I’ve been using this COSRX toner serum for a few weeks now, and I’m honestly obsessed. It has a super lightweight, watery texture that absorbs quickly but still leaves my skin feeling really soft and refreshed. What I love most is how hydrating it is without being heavy or greasy. My skin feels smoother, more plump, and definitely looks more even-toned. I’ve even noticed my makeup sitting better throughout the day. It’s gentle enough to use morning and night, and I’ve had zero irritation. I also love that it has peptides, niacinamide, and hyaluronic acid all in one—it saves me a step in my routine and still gives great results. Perfect for layering or using on its own if you want something simple but effective. Highly recommend if you want a no-fuss product that makes your skin feel healthier and look glowier! ... show more
