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.

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!

This confuses me but it’s nice. I thought it was a facial Mist but it’s not. It has a squirt top which I love but it’s thicker like a like a phyto-mucin so it fits into the serum part of your routine. I like that it’s scent free for the most part and love how it helps my skin. I give it a 4 and not a 5 mostly bc I didn’t and still don’t entirely understand the product.

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!

BEST EVER! Do not sleep on this product. It is the holy grail in my skin care routine. I’ve been using it for over a year now and the value price point is unbeatable. I get about six months use out of one bottle and I use it every morning and every night. It keeps my skin so soft, bouncy, and honestly looking like my teenage skin all over again at 32 years old! The packaging is really cute and minimalistic and you completely get a full bottle of product. I would recommend this to anybody and everybody. It completely controls the sebum I used to get in my T zone area and also has had a great effect on my hormonal acne when I do have breakouts. If it does have a scent, I honestly do not notice it, but after directly smelling it, it does have a lingering freshness to it that is extremely mild. It is just so great you guys if you’re having any doubts, don’t have any doubts. I promise you will not be disappointed in this product!

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.
