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

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.

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.

This serum is fantastic! It’s packed with beneficial ingredients like collagen, peptides, hyaluronic acid, amino acids, and NAG, all of which make it feel like a complete skincare boost in one bottle. The texture is lightweight and absorbs quickly without leaving any sticky residue. It’s easy to layer under other products, and I love that it combines so many active ingredients in one formula. I'd recommend this serum to anyone looking to improve skin hydration, firmness, and overall radiance.

Love this as part of skincare routine. Deeply hydrates. I put it on as my second step after rice water. I noticed a big difference in my skin when I tried another so would not be without it now

Another one of my favourite brands I highly recommend this brand to anyone of all ages it’s literally the best I bought this with the snail gel and cream and I use the needle cream with it makes your skin look like glass n it lasts for days on your skin (the glass look) it’s really good absolutely invest in this if your looking for a good skin care product this is the one

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.

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.

It leaves the skin felling comfortable and not tight after applying, and it gets it ready for moisturising, but I haven't noticed any significant results.

C’est top ce produit! j’ai une peau tres reactive et asez sensible, mais Il me va tres bien comme base avant autres sérums/produits. Sa texture est tres leger et tu peux l’appliquer en plusieur couches. Ça booste l’hidratation j’aime beaucoup

Wow such a great peptide booster.I love it from the first use.this is my first peptide serum & I’m soo satisfied with the texture and the result.

Excelente producto.

Doesnt feel like a thick product, amazing

This booster serum is a powerhouse. It feels like a professional skincare treatment in a bottle. The formula is incredibly lightweight, almost watery, but it delivers intense hydration and firmness. My skin feels bouncy, smooth, and refreshed immediately after application. After consistent use, I noticed improved texture and a subtle tightening effect — especially around my cheeks and jawline. It layers perfectly with other products and never pills. The combination of peptides and niacinamide makes my skin look brighter and more even. This is one of those products that quietly upgrades your entire routine. It’s gentle, effective, and suitable for daily use. If you want that glass-skin glow, this is a must-have.
