COSRX 6 Peptide Collagen Serum Face Toner with Niacinamide & Hyaluronic Acid, Hydrating & Firming Korean Essence, Anti-Wrinkle & Pore-Tightening Serum For Plump & Even Skin Tone, Korean Skincare 150ml

I hesitated before buying this because of the large size and the fact that it’s Korean skincare — which can feel very different from Western products. But I’m glad I tried it!This serum (or essence, it feels somewhere in between) is quite watery in texture, but not runny like water. It spreads easily and you only need a small amount, so the big bottle will last a long time. However — and this is key — it takes time to absorb. I usually wait 5 to 10 minutes before applying anything on top, otherwise the next layer (like cream) just slides off and the skin doesn’t feel as smooth.But if you wait, the results are absolutely worth it. My skin feels incredibly soft — almost baby-skin level. It hydrates deeply, brightens the tone, and improves texture. It even seems to have a mild evening/brightening effect.No irritation at all on my very sensitive skin. I checked the ingredients on the Yuka app and it scored 100/100 — no harmful or problematic components. There’s no noticeable scent, which I appreciate. The formula may contain some synthetics, but nothing that caused any reactions for me.In short: great value, amazing results, just give it time to do its job. I’m very likely to repurchase once I finish this bottle.

An amazing serum full of various peptites including copper peptides. It's quite a watery consistency but this doesn't stop it being a great product. The amount you get is great and it's easy to use on your face and chest.It's made my skin softer and reduced fine lines slightly. Skin appears more glowy. Skin texture is also better. I used this before applying vitamin c and niacinamide serum, it all absorbed really well.

I use this after cleansing as it apparently helps the efficacy of other serums and toners and gives me a glass effect. It’s super watery but it hydrates the skin quickly and dries quickly as well. I sometimes use this and then put on a peptide face mask for extra peptide goodness. It is quite expensive but I buy it on sale and honestly it seems to go on forever so I do think I get bang for my buck. I have noticed a difference in my skin tone and softness so I will carry one and buy again. As with all these things, long-term use and consistency is key and it may not work for everyone, but I love it’s clean feel and hydration/glass effect.

Bought this because I had other items from the same line and it’s great. It leaves my skin feeling soft, and if you are someone who used things like retinol it really does help then absorb. I’m in my mid 50s and I’m a complete convert. Moisturiser applied on top also seems to absorb better and, on the rare occasions I actually put makeup on, it sits really well and doesn’t slide or crease. This makes me feel like my skin looks fresher and plumper and my fine lines are gone. Even my 1 deeper forehead crease is barely noticeable.It also causes no irritation.

A great product. I can see an improvement in my skins texture. Lasts a long time. Good value for money. I recommend this product

This product has been a complete game changer for my skin. Currently about to order my third bottle. Prior to this, my skin was quite dry and dull. Within two weeks of daily use, I could see the difference in the moisture and dewiness of my skin. I also have quite sensitive skin and I had no reaction. Definitely worth the price!

Brilliant product, lovely on the skin, absorbs fast and not sticky at all.

Nice looking bottle, the product is temporarily hydrating and has a nice feel and appearance.But my skin has broken out pretty badly, and just a word of warning: peptides are not supposed to cause purging. So sadly I won’t be using or buying this again.
