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!
