[This review was collected as part of a promotion.] Almost water-light in consistency, so it absorbs instantly and never feels greasy. I applied it right after cleansing before thicker serums and it always layered well. Simple, gentle, and no weird residue.

Makes skin look hydrated
[This review was collected as part of a promotion.] It’s a decent sized bottle. I like the consistency of this product in this type of packaging that has a type of pump. Some serums are too liquidity with a dropper which makes a mess. This product makes my skin look hydrated.

Excellent Product
[This review was collected as part of a promotion.] Hello to all skincare lovers! I just started using COSRX 6X peptide collagen tonic serum and I'm impressed! My skin feels much more hydrated from day one, something that doesn't always happen with tonics. Niacinamide is a star ingredient for spots and pores, and it seems to be working wonders. In addition, hyaluronic acid gives a juicy and healthy glow to the skin. The texture is light and absorbs very quickly, perfect for use before moisturizer. Honestly, I highly recommend it! If you are looking for a product that gives you hydration, brightness and helps you with the appearance of pores, this is the right one.

Suitable for dry skin
[This review was collected as part of a promotion.] I received this product in exchange for my honest review. I think it is a decent product for those that have dry skin. I have overly oily skin and this product made me experience breakout. Again, I think if my skin was dry/lacking oils, this product would be my holy grail. There isn’t much of a scent. Consistency is very watery and smooth.

Great product

I’ve been using this product
[This review was collected as part of a promotion.] I’ve been using this product daily for about a year. Along with many other COSRX products but with this one I find it hard to tell if it makes a difference or not. I know peptides are good for your skin so I still continue to use it.

Being consistent will get results!
[This review was collected as part of a promotion.] I’ve been using the COSRX 6-Peptide Skin Booster Serum for a while now, and I’m really liking it! It’s super light and refreshing, and you can layer it a couple times for an extra boost. My skin’s been smoother, brighter, and way more hydrated. Trying to be more consistent with it because it actually works. No scent really and I like the size of bottle.
