[This review was collected as part of a promotion.] It’s lightweight and doesn’t leave you feeling sticky. Packaging is sleek and simple. For me, it doesn’t have a scent. It adds a moisture to my skin.

[This review was collected as part of a promotion.] I'm blown away by this skin booster serum! It's given my complexion a noticeable radiance and glow. The formula is lightweight, yet potent, and absorbs quickly into my skin. I've seen a significant reduction in fine lines and wrinkles, and my skin texture has improved dramatically. It's also helped to even out my skin tone and reduce the appearance of pores. I've been using it daily, and I'm so impressed with the results. It's definitely a new staple in my skincare routine!

[This review was collected as part of a promotion.] Love this serum! It feels really nice of my skin and doesn’t leave my skin feeling sticky afterwards. The scent is very light which I also appreciate and I would definitely get this again!

I have never left a review before now. I tried this as a "free birthday gift" from ulta. At first, i thought my skin felt super soft and thought i may have found a new product. Then within 5 min..the redness began. Then burning, then severe itching. I immediately went to wash my face thoroughly. 3 bendadryls later and ice packs the swelling, redness, burning and itching began to subside. I am not quite sure what I'm allergic to in this. But people with sensitive skin should be very cautious about using this.

[This review was collected as part of a promotion.] When I’ve used this serum, I felt like it boosted my other products at the beginning. It has a clean feel. It doesn’t leave a residue on your skin. It doesn’t have a scent. The packaging was nice and clean. It’s been a nice addition to my routine.

[This review was collected as part of a promotion.] Rating: ⭐⭐⭐☆☆ (3/5) I had high hopes for the COSRX 6 Peptide Skin Booster Serum, but after several months of consistent use, I didn’t notice any visible difference in my skin. The application was pleasant—the texture is lightweight, absorbs quickly, and layers well with other products without any pilling or stickiness. That said, I was hoping for more noticeable hydration or firming benefits from the peptides, but my skin didn’t feel any different than before I started using it. Compared to other COSRX products, I definitely prefer their Snail Mucin Essence, which delivers much more hydration and a visible glow. Overall, it’s a decent lightweight serum, but for me, it just didn’t deliver results worth repurchasing. If you’re looking for a peptide product that makes a real difference, you might want to explore other options.

[This review was collected as part of a promotion.] I absolutely love the COSRX The 6 Peptide Skin Booster! This serum has been a game-changer for my skin. It provides deep hydration, making my skin feel firm, smooth, and refreshed. After just a few uses, I noticed a more even skin tone and an overall healthier complexion. The lightweight texture absorbs instantly without any sticky residue, which is a huge plus for me. With hyaluronic acid, NAG, and amino acids, this formula works wonders in improving skin texture and balancing oil production, making it suitable for various skin types. Bonus points for the sleek, minimalist packaging and the convenient pump dispenser. I’ll definitely be repurchasing!

[This review was collected as part of a promotion.] Today I want to share my impressions of Cosrx The 6 Peptide Skin Booster/Serum. The product pleases with an excellent volume - 150 ml. The packaging is made in the brand's signature minimalist style, it is a neat cardboard box. One of the main advantages is the convenient pump dispenser: it is pressed smoothly, does not jam, does not splash the product to the sides and gives out the optimal amount of product. This peptide booster has a medium-dense gel texture that is pleasant to the touch, does not leave a sticky or oily sheen. There is no smell. I use it twice a day on cleansed skin. According to the rules, the product is applied after the toner, but I am comfortable using it instead of the toner or before the serum. I prefer to apply a generous amount, so the effect becomes more noticeable. At the same time, the product is quickly absorbed, leaving no stickiness and not interfering with further care. This booster has a cumulative effect, so it is important to combine it with other care products. In my experience, the skin looks better with it – it becomes more elastic, smooth, moisturized, with an even tone. However, I did not notice any dramatic changes. Overall, the product is pleasant to use and gives the skin additional care and comfort.

[This review was collected as part of a promotion.] It was ok…I don’t feel like it really did anything for my skin besides make me somehow more oily?? The consistency is pretty much like water. Felt more like a watery toner. Packaging looks similar to the Cosrx brand as always. There was no scent.
