Great product
[This review was collected as part of a promotion.] Very easy to use and pump out. The texture is light weight and I honestly didn’t notice a fragrance. I feel like within weeks I could notice a difference in my gas, brighter and even a bit firmer.

Lightweight and hydrating
[This review was collected as part of a promotion.] I actually got the COSRX 6 Peptide Skin Booster gifted from Influenster a while back, and I didn’t think much of it at first… but it’s seriously become one of my skincare staples. It’s super lightweight, absorbs fast, and makes my skin feel so smooth and hydrated. I love how it layers perfectly under other products — no stickiness, no pilling, just that nice glowy finish. I’ve been using it for about two years now and have repurchased it multiple times. Definitely one of those products I didn’t expect to love, but now I can’t skip it.

Super plumping!
[This review was collected as part of a promotion.] This is super hydrating and very good for sensitive skin like mine. My mom became obsessed with it and always wants to buy a new one. So it’s also great for older skin for sure! Definitely helps even out the appearance of wrinkles & fine lines.

Hydrating, effective, no fragrance
[This review was collected as part of a promotion.] I was given this product in exchange for my honest review. Formula of the product feels like a thicker water but more runny than a serum, it is something in between. I was using this as a toner after washing my face and before applying serum and moisturizer. If you pat it onto your face with your palms it will absorb quickly, calm, hydrate your skin and prepare it for next steps. I haven’t noticed any improvements in skin texture, it’s just moisturizing water-like toner, don’t expect wonders. But it definitely calms skin and makes it feel nicer that without it. Bonus-it doesn’t have a smell. I would recommend if you need extra hydration, just don’t expect miracles.

It doesn’t hurt to add
[This review was collected as part of a promotion.] This product was honestly just a like for me . The texture was too watery for my liking but it definitely didn’t hurt to include in my in my skin care routine. But it didn’t make enough of an impact for me to repurchase but it’s worth finishing

Amaizing
[This review was collected as part of a promotion.] Corxs is one of my favorite Korean brands and this peptide serum is amazing. The texture is super light, fragrance-free and absorbs quickly. I would really buy it again, I have seen a great improvement in my face. It has a number of ingredients that are incredible for the skin, if I recommend it.

Not great for me
