Big size and gentle to use.

I have dry/sensitive skin and i can't get enough of this product! I've loved COSRX and tried several products over the yrs and this did not disappoint. I use this after toner but before serum. It has a light/watery texture and is great for layering hydration. No stinging or irritation which is a plus with my skin type. I will definitely be repurchasing this when I run out, which is saying a lot since I try so many skincare products.

I am using it as the first product before skin care, and I have seen great results when using retinol products or vitamin skin care products to brighten my face tone. I have been using it for over a week and the effect was minimal, my skin has improved so much since using this product. I will repurchase this booster

I really like it and would definitely recommend it and purchase again

This is a light serum that works like an all-in-one type product. It's a hydrating serum that deeply nourishes my skin. It firms and smooths fine lines. I like to mix this with their vitamin C serum because it helps brighten and even out my complexion. I definitely recommend it.

good product with good price offer, i purchased many items

The way my skin soaks this up is crazy. I’ve only been using this for a week and my skin hasn’t been dry, the dark marks are fading fast, and it helps keep my acne at bay. Of course I still get the occasional hormonal acne because I am 26 and I wear different makeup everyday, but it’s like 1-2 pimples max compared to the dozens I used to get. This is a game changer in your skincare routine. I can’t live without this!

During the holidays and winter school finals, my skin becomes stressed and gets breakouts. This winter I wanted to treat my skin a little better so I could have the most amazing holiday photos. This Peptide serum goes on so light, yet it penetrates through the skin, leaving it bright, smooth, and glowing. The best thing about this serum is that you can combine it with other products for extra benefits.

The 6 Peptide Skin Booster offers a watery, nearly weightless consistency that swiftly absorbs without any residual greasiness. I appreciate its ability to leave the skin feeling soft and primed for subsequent skincare steps. In my view, it proves most efficacious when applied as the initial skincare step following cleansing, before the application of toner.

This adds a layer of hydration and moisture to protect the skin’s barrier during this winter. It’s a lightweight serum that absorbs instantly and moisturizes the skin. My skin is enjoying this one

First time trying this booster and I was really surprised about how this serum worked a bit different from the “regular” ones, it still does a great job and manages your skin really well!

I really wanted to like this--and I do! It's lightweight and easily absorbs into my skin as a precursor to the rest of my skincare. It provides just a bit of extra hydration and I feel like it really does help my other skincare products to also absorb faster and more completely. Obviously it layers well and I love the idea of having extra peptides in my routine so this has been a winner for me.

I received it as a gift for my honest review. It is a lightweight liquid that is easy to spread on the skin and is well absorbed by the skin. Leaves the skin soft and radiant. It's only 1 or 2 pumps and your skin feels great! I see the difference after using it! My skin is better, smoother, and good-looking. I love it and will continue to use it! Recommended!

One product filled with so many benefits to the skin. This product also absorbs so easily into the skin. It’s a great prep for the rest of your skin care.

This serum is amazing it has a silky watery consistency that just glides on your skin leaving hydrated and glowy. Peptides are great for fine lines and wrinkles perfect to maintain the skin moisture. I am really loving this serum it is perfect for dry skin especially for this winter season.

So far I find my skin to be hydrating from this product I felt my skin less dehydrated

I have heard so many good things about this product so I’m really happy that I got it at a good price. It’s really nice to use right after cleansing like a toner and my skin just sucks up the product. It leaves a nice glow on my skin too.

Good quality product for reasonable price

This is so awesome! I mean the moment I use the fluid goes into my skin and makes my skin so soft! It’s hard to describe but you can feel your face is hydrating and the laying serum or ample soak into the skin and makes you really plump! So lightweight into skin! I need to stock up this and it’s my HG! Good job to Cosrx!
