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

COSRX The 6 Peptide Skin Booster Serum is a lightweight, fast-absorbing serum with 6 peptides, niacinamide, and hyaluronic acid. It deeply hydrates, smooths the skin, and improves overall texture without feeling sticky or heavy. With regular use, skin looks more plump, fresh, and healthy, with a subtle anti-aging effect over time. Great for layering under moisturizer or makeup and suitable for most skin types.

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.

At first it appeared watery, yet using it leaves a nice tightening to the skin and small imperfections are fading rapidly. Doesn't take a lot of it as it is very thin and like water in the hand. Pleased so far after the very first use noticed a marked difference! P.S. it is my wife who wrote the review and uses the product just to be clear :)

Absolutely love this as a first layer serum, it contains HA so you can skip that and go straight for this, full of skin loving peptides, so light on the skin, large bottle but lasts absolutely ages, absorbs very fast due to it being watery but this is good as you can then layer thicker serums on top. I’ve spent a fortune on skincare products now I’m 49 and really need to look after my skin now. When you are young a good moisturiser is all that’s needed and possibly this as a first step but as you get older your skin needs more attention and this product ticks all the right boxes. It’s expensive but lasts a long time so if you break it down it’s great value for money. I would love if they added matraxyl into this serum/toner as I’m having to use a separate serum for that afterwards. I’m going to start pairing this with snail mucin and see if it makes a difference but been using a good while now and I can definitely see results, my skin is hydrated and more even tone and looking plumper. With skincare try just adding one new product at a time so you can see the real results. That’s what I did with this product and the results are amazing and worth every penny. Don’t be put off by the watery consistency it just means it absorbs faster. You also don’t need a lot 2 pumps is more than enough (sometimes we see a big bottle and think we need to use a lot but really you don’t. I’ve been using a good while now and there’s still loads left!!! Definitely recommend especially for mature skin. I have sensitive skin and have had no issues whatsoever. It’s one of my go to products now.

Love this product! After washing my face with cleanser and water, i pat my face dry, then use a layer or 2 of skin toner. Then I apply this serum. It rubs in nicely to your face. It leaves your face feeling fresh and adds a light glow. Sometimes I add another serum to the product, or if I'm in a rush I add moisturizer to the serum and apply both together. The glow will remain on your skin throughout the day. The glow is gentle. (and not to be mixed up with looking greasy or shiny from products that are too heavy or not rubbed into the skin properly) No stickiness noticed from this product, and it feels light and gentle on your face. It seems to have evened out my skin tone and my skin feels adequately hydrated after I use it. Initially i thought it was a little pricy for the product, but it is a large bottle and is lasting very well. I use 3 pumps worth each time I use it. So I would say it is priced fairly. My skin received several compliments when I wear this serum because of the gentle glow, plumpness and hydration factors. I have never worn a lot of make up throughout my life, but this serum could hopefully give you the confidence to also have a more natural look. I originally purchased because I noticed my skin seemed dryer - possibly due to the menopause. I am 56 years old, and would recommend this product for mature skin.

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.

I really love this. It leaves my skin super smooth and healthy looking. I would buy it again!

Been using this now for a month and have seen no improvement on my skin. Maybe this will work on younger skin (I am 50) and prevent wrinkles and sagging. I can buy much cheaper products and get the same results.
