Review: Amazing hydration, lightweight and effective - This COSRX Hyaluronic Acid Serum is amazing. It feels very lightweight on the skin and absorbs quickly without leaving any sticky feeling. My skin feels deeply hydrated, soft, and plump after using it. It works great under makeup and layers well with other skincare products. A little goes a long way, and the quality is excellent. I highly recommend this serum, especially for dry or dehydrated skin.
Review: Very hydrating - calms rosacea redness - First you must know this isn't a full ounce but .67 ounces - they could do better with making sure that is front and center so customers know the amount. I am a little disappointed in COSRX for not being completely transparent about that. I really had to search to find the amount. I adore COXRX skincare as my skin absolutely loves it, but this is where they drop the ball. That out of the way --- The serum is beautiful. It's medium thick clear. Glides on my skin so smoothly. Very hydrating. I pair this with the COSRX snail mucin - it took me a long time to order snail mucin as it is a little gross and I make sure to avoid my lips (ew), but the two together calm down my rosacea redness--I have Type 1, which is redness and flushing - stinging if my barrier is compromised. This has Sodium Hyaluronate, which is the better hyaluronate as far as it has a smaller 'molecule size' so it can penetrate better--at least this is what I understand. The fourth ingredient is glycerin, which is very hydrating, and adds a lot to the formulation. I put this on damp skin, and whether I use the snail mucin first, second, or not at all, after applying on damp skin I dampen a makeup sponge or use damp fingers to pat and press more moisture into my skin. I let that 'sink in' for a while - 3-5 minutes or sometimes longer before going on with my skincare. Sometimes my cheeks will be red and this along with the mucin will immediately calm it down - well, immediately as in about 30 seconds or so after applying. Even the act of applying skincare can make my cheeks turn red. I love that COSRX is not expensive at all - even at less than an ounce, it's still a bargain. This along with Beauty of Joseon are my two favorite K-Beauty brands and I don't use much of anything else anymore.

### ⭐⭐⭐⭐ COSRX sodium Hyaluronic Acid 3%
*by S***. on September 21, 2025*

It's a good thing I had an old dropper, longer than the one the product came with. The dropper it came with was not absorbing the serum, but when I used my own dropper it worked. The serum itself is great. I immediately saw a difference in my skin.
