COSRXPure Sodium Hyaluronic Acid 3% Serum, Hydratying & Moisture Boosting for Fine Lines & Wrinkles, Repair Dry Skin, 0.67fl.oz/20ml, No Artificial Fragrance, Korean Skin Care, Stocking Stuffers

3% HA compared to most brands 2% or 1% makes so much difference. Make sure your skin is actually wet as opposed to just damp, though.

Me encantó! Lástima que ya se me está acabando, me tocará volver a ordenarla, pues ya se convirtió en uno de mis favoritos. Dura mucho y es ligero.

Déjala piel muy hidratada tiene buena consistencia el producto no es pesado en la piel se adhiere muy bien

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.

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.

My bottle only lasted about 2 weeks, so I feel like it wasn’t full. Also has me concerned about whether the product in the bottle was actually what it says it is. I will buy again to try, but thru a vetted distributor like Sephora or Ulta.

Me gusta como me deja la piel e mi cara

The bottle was completely empty. At first I thought it wasn't sucking up into the vial however, I turned it upside down ans stuck a q tip and it was completely empty.
