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.
Review: Noticeably More Hydrated Skin (Even My Aesthetician Said So!) - I’ve tried quite a few hydrating serums over the years, but this COSRX Pure Sodium Hyaluronic Acid 3% Serum really stands out. After incorporating it into my routine, the difference in my skin’s hydration was noticeable pretty quickly—but what really sold me was when my aesthetician commented on it without me even mentioning I’d changed anything. She said my skin looked significantly more hydrated, which says a lot! The texture is lightweight and absorbs easily without leaving any sticky or greasy residue. It layers well under moisturizer and makeup, and I’ve found it works great both morning and night. My skin feels plumper, smoother, and more refreshed overall, and I’ve noticed a subtle improvement in the appearance of fine lines, especially around my forehead. A little goes a long way, and the bottle has lasted me quite a while even with daily use. It’s simple, effective, and does exactly what it promises—deliver hydration. Pros: Deep, noticeable hydration Lightweight and fast-absorbing Non-sticky finish Layers well with other products Aesthetician-approved results Cons: No major downsides for me so far Photo Suggestions: Before/after close-ups of your skin (especially in natural lighting) A drop of the serum on your hand to show texture Your skincare lineup featuring this serum A fresh, dewy skin shot after application This has become a staple in my routine—I’ll definitely keep repurchasing!

### ⭐⭐⭐⭐⭐ Very hydrating - calms rosacea redness
*by K***E on September 14, 2024*

### ⭐⭐⭐⭐⭐ Doesn't pill, lighter feeling that other brands
*by M***C on November 7, 2024*

I have used hyaluronic acid daily for several years. I top it off in the morning with a light moisturizer followed by sunblock. This review is based on that usage. The pros: - I have no pilling with this product. I have used The Ordinary hyaluronic acid and found that it causes pretty distressing levels of pilling. See above, I layer my products. Alone, other products may not pill. If you layer, this is a good option. - No odor. I have purchased other products from other brands that have a pleasant odor. I like that this brand is unscented, but as we all know, being unscented and having no odor are two different things. Gasoline doesn't have fragrance added, but it's stinky. This product has no odor, either when applying or when dry. - Effective. I haven't taken photos to know how effective this is day to day. I always use it, my face is getting older (it is what it is) and I think I'm holding up pretty well. I will say, if I don't put it on right after my morning shower, I feel the difference. I feel dryer, and my skin is less "springy". - Pretty container. This might not be a pro to someone else, but if you have a little display for your lotions and potions, this looks nice on display. Cons: - It is costlier than other brands, but not prohibitively. - The container is a weird shape. It's also black. It is not possible to know how much you have left, and it's hard to get the last drop. Overall, I have bought this a few times and will be buying it again.
