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

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.

This product is accurately described as a toner serum. It has the lightweight, fast-absorbing texture of a toner, but functions more like a treatment serum. Rather than focusing only on hydration, its real strength is how well it prepares the skin and enhances the performance of products applied afterward. With consistent use, I’ve noticed clearer skin, a brighter and more even tone, and gradual improvement in dark spots. The effect is especially noticeable when pairing it with active treatments such as vitamin C serums. How I use it (evening routine): In the evening, I apply a thin layer and gently pat until fully absorbed, then repeat this step 2–4 times, depending on how dry my skin feels that day. Building hydration gradually this way allows the skin to absorb moisture without heaviness and noticeably improves plumpness and overall moisture retention. Once the toner serum is fully absorbed, I apply my treatment serums (such as vitamin C), followed by a moisturizer with enough oil and hydration to seal everything in. Used this way, it clearly improves how well active serums absorb and perform, leaving the skin looking fuller, healthier, and well-hydrated. Morning use: I also use this in the morning, but usually apply just one light layer. It noticeably improves makeup application—foundation goes on more evenly, adheres better, and stays comfortable throughout the day without emphasizing dryness. I hope this review is helpful for anyone deciding whether this fits into their routine.

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.

This product dries faster than I works like. I have to apply it several times to complete my face massager. I quickly learned to apply ot only in the area I am treating and then again to the next. I was happy it didn’t have a scent and it was so smooth that I didn’t have to wash it off. The consistency was more like water. Hence, why it probably absorbed quicker than expected. It did make my skin feel soft and I will continue to use it to see if the appearance of my skin improves.

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

I love peptides, as I find them effective and they don't typically irritate my super sensitive skin (rosacea, ezcema, etc). I've used various serums over the years, and decided to give this one a whirl. After my typical patch testing for several nights with no reaction, I began using it initially on my neck and chest, and eventually on my face, as well. After consistent use for several months, I saw a definite improvement in the texture and tone of my skin. I was happy to see some improvement in the laxity of the skin on my neck, which was thrilling. I use it under moisturizer, with a richer one for my drier neck skin. I have experienced no pilling, and my moisturizer absorbs well on top. I appreciate that it's cruelty free, and the large size makes it an exceptional value. I use it nightly over my entire face, neck, and chest, and the bottle lasts for months. This is a keeper for me.

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!
