The COSRX Pure Sodium Hyaluronic Acid 3% Serum is a fantastic addition to my skincare routine! This serum is lightweight yet incredibly effective in hydrating and locking in moisture. I’ve noticed a significant improvement in the texture and plumpness of my skin since I started using it. The 3% concentration of sodium hyaluronic acid is just right, providing deep hydration without any sticky residue. It absorbs quickly, making it perfect for layering under my moisturizer. I highly recommend this serum for anyone looking to boost their skin’s hydration and achieve a more youthful, radiant complexion.

I really like this skincare product—it feels great on my skin and shows results. However, I was disappointed that it ran out in just two weeks. The black bottle design makes it impossible to see how much is inside, so I had no idea how quickly I was using it. While the product itself is amazing, I wish the bottle was more transparent or had a better indicator for the level.

The bottle was almost empty when I received it. The dropper couldn’t suck up any serum because it was down to the bottom. I tried it a few times and finally took the inner cap out to look in the bottle and there was only a little on the bottom of the bottle.

This serum has really made a difference in my extremely dry skin. Have added other Cosrx products to my Christmas list!! The cost of these products is very affordable and they WORK!

I love using hyaluronic acid, I have previously used some HA but this one ticks all my expectations . My skin looks glowy and feels very moisturised. On the other hand I feel the product runs out very quickly if you use it daily ( day and night ) . But comparing the price and quality is very worth it . I like it my skin feels plumped .

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.

This Hyaluronic Acid 3 was just about empty.
In order for me to use it, I had to tilt the bottle so the pump could actually get some in the tube. I can put the bottle on its side and nothing will come out. I decided to see how far I can tilt this just to see when I’ll be able to see the liquid. About 3/4 tiled when I started to see the liquid. I should empty the bottle just to see how much is actually in it. I’ll be looking for a different brand…. Update.. ( Jan 10- 2024 )
I changed my Star rating from 1 to 5 because the seller gave me a full refund because of my empty bottle I received.. They reached out to me and said they will take care of this.. Great customer service. I will order again from this seller.

本当に、スポイト一滴で、化粧水を沢山目に混ぜないと、却って固まりそうなほど、(最初はトロトロなんですが、伸ばすと)
しっかり水分保持してくれます♡
で、まあ、40倍分を一気に両手でつけるのは難しいので、私は片手にこれをスポイトで一滴(少なめで)、化粧水を溢れないくらいに混ぜて、顔に伸ばしてから、
もう一回同じくらいの量の化粧水を追加で
顔に伸ばします。
そのくらいでなんとかちょうど。
でも、とてもとろとろサラサラなので、
顔の皮膚を引っ張らずに済むので、
とても良いと思います🎶

Keeps your skin hydrated for a very long. I use it as a base for my make up.

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.

This serum really works! At first I used it every day, underneath my sunscreen and makeup, and people noticed! It helps with not just fine lines, but even deeper marionette lines. Put it on while your face is still wet after washing in the morning, and let it dry — then apply sunscreen/moisturizer and makeup. Since it is a little expensive, I stopped using it every day and only use it on days I am going somewhere special — 2-3 times a week. Still works, just not as dramatically as using it every day. It also plumps up your skin a little, and is hydrating.
