Fantastic Peptide Serum - A Game Changer for My Skin!

Reviewed in the United States on October 29, 2024

After being disappointed with TO’s “Buffet” serum and not seeing any results from other peptide creams (or collagen supplements/powders) and becoming a newfound fan of many of the products sold by COS RX, I decided to add their peptide serum to my skincare routine. I am absolutely thrilled with the results! From the first application, my skin felt noticeably smoother, plumper, and more hydrated, with results appearing very quickly. The serum absorbs quickly without leaving any sticky residue (it’s not like the snail products), making it perfect for layering under my serums and moisturizer.

After just a few DAYS of consistent use, I've noticed a significant improvement in the texture and firmness of my skin. Fine lines appear diminished, and my complexion looks more radiant and youthful. I love that it doesn’t have any fragrance or harsh chemicals, making it suitable for my sensitive skin. Despite having rosacea and being acne-prone with sensitive skin, this product does not make my skin react angrily, which is a huge relief. It pairs great with the COS RX Essence. It’s not moisturizing enough to use on its own for my dry skin, but it doesn’t claim to be.

One point of confusion is the suggestion to replace this with your toner. To me they serve two different purposes. Personally, I use it after my toner/exfoliator or throughout the day for an extra boost of hydration since it’s so lightweight, and it works wonderfully for me. I don’t wear makeup so I can’t speak to how well it is under makeup, although it’s water-like consistency leads me to believe it won’t affect makeup. It doesn’t pill when layering other skincare products.

The packaging is also a plus—it's sleek and features a hygienic pump that dispenses the perfect amount of product every time. A little goes a long way, so I feel like I'm getting great value for my money.

Overall, this peptide serum has exceeded my expectations, and I couldn't be happier with the results. I highly recommend it to anyone looking to enhance their skincare routine and achieve glowing, healthy skin. This product is definitely a staple in my beauty regimen now!

I have been using 4 CosRx products and I have been recommending them to friends. There is no smell and I believe it to be a good value for the money. One bottle roughly lasts 4 months. I use it morning and evening. I definitely think that it has made my fine lines less noticeable and has provided extra moisture and improved the texture of my skin. I think that it has also helped my botox last longer ????. I will continue to use this serum. Love it! It absorbs really quickly and it is very thin which feels like water on the skin. There is no stickiness to worry about.

No irritation, very mild and easy to use

I'm loving this. My skin is so sensitive, this does not give me any issues. I suspect that the concentration of peptides is low in this, but for the price that is fine. I apply it as a first step after cleansing before moisturizer. I feel it gives just a touch of hydration and a boost for my skin. It doesn't feel sticky or leave a residue that I notice. Feels almost like nothing just a hint of moisture.
I use this all the way up to my lash line without triggering eyelid dermatitis. Love it.

Amazing Results!

Reviewed in the United States on July 14, 2024

I've been strictly using COSRX products for over 5 years now and I recently added this collagen booster peptide serum to my morning routine, and I've noticed a significant brightening of my skin, and reduced redness on my cheeks. I take the vital proteins at least four times a week, and also use the COSRX birch sap moisturizer after applying this serum. At night time I use the and the hyaluronic acid moisturizer with the eye cream, and I feel that my skin just works so well with COSRX products and none of them break me out. The one step clear pad is my non-negotiable and it clears my skin before I apply the serum, it is light and absorbs quickly into my skin. I feel that my skin has become softer because of it and I would highly recommend this product to anyone who is considering it. You only need a small amount for it to work well so I think it's worth the price and will last me a while too.

Feels good but I’m not sure it really makes a huge difference

Love it!!

I really like this serum. Very thin and watery, almost like an essence/toner. Because of how thin it is, it absorbs almost immediately. The peptides in this formula are legit, I have seen great results after a year of using this twice daily. I'm on my 2nd bottle now and don't plan to ever be without this serum. Highly recommend for all ages and skin types.

Really great! My skin is now glowy, less oily and my pores don’t look as large as before. No scent which is what I wanted. The bottle size is okay (a little goes a long way). It’s hydrating to me and soothes my skin.

I love it!

Reviewed in the United States on October 25, 2024

I have been using this for about a week, and my fine lines do appear to be smoothing out under my eyes. I am glad it works in the under eye area and on my neck, because most products I put in these areas will burn like fire and turn my skin red and scaly, so I can't put them there. This product, however, is very gentle and it also doesn't have a scent.

The bottle is pretty big, since I only need about three or four pumps to do my whole face, neck, and décolleté. It dries down pretty good, as well. I don't detect any stickiness, but I also put a retinol serum on everything but my neck and under eye area, and use two different moisturizers - one under my eyes and another all over to lock in my serums. I use this in place of a toner, because I already use so many other products; I add them one at a time, and this one has definitely had an effect. I wish I had done a before picture, because it's kind of dramatic.

I love it so much that I'm going to try their moisturizer, and hope it can be used all over...maybe save me some money. I'll definitely be reordering this one!
