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.

It feels silky on the skin and layers well with other products. The peptides and niacinamide make my skin look more even and refreshed. A solid everyday serum.

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.

Always love a good peptide Great for skin Lasts for me about 5 months even when I overspray Lovely packaging use it Seen a difference in skin texture and black spots No fragrance It is definitely with investing in

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.

Fragrance free. Consistency it’s super light. Effectiveness it’s somewhat quite good. Skin comparability it’s amazing you can pare it with anything. There is no residue make sure you let it dry free

I bought this on a whim last Prime Day - we’ve all been there! - because I’d liked other COSRX products and thought it was worth a try. At the time I was thinking it was just a toner, but on closer look at how to apply realised it was intended to boost efficacy for the whole skincare routine. I was sceptical, but it seemed worth a go, and as I’m finally starting to look my age I had nothing to lose. I’m genuinely impressed with this. It’s now an essential first step in the routine after cleansing. The watery texture makes it easy to apply quickly across the whole face. I usually only apply one layer, but the manufacturer also suggests layering, which I might try if I don’t have a serum to add into the mix. Applying just this plus a moisturiser leads to lovely soft skin, more so than with moisturiser alone as I did a side by side test to see: I’m a nerd, sorry. At night time, I pair this with a couple of Beauty of Joseon products: the revive eye cream and the revive moisturiser, both of which contain either retinal or retinol. Together they make a pretty unbeatable routine and I’m finding my skin smoother and more radiant the more I stick to it, more so than had I not used the peptide booster. Despite the watery texture, a bottle of this lasts ages. But I will be buying it again because I don’t ever want to run out.

This is ok but the mucin snail stuff is better and cheaper. This is so watery. No like
