5.0 out of 5 stars Very hydrating - calms rosacea redness

K.M. · September 14, 2024

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.

5.0 out of 5 stars Love CosRx

I have been using 4 CosRx products and I have been recommending them to friends. There is no smell and I believe it to be a good value for the money. One bottle roughly lasts 2 months. I use it morning and evening. I definitely think that it has made my fine lines less noticeable and has provided moisture and improved the texture of my skin. I think that it has also helped my botox last longer 😉. I will continue to use this serum. Love it!

I am trying out entire life e after a lifetime with Shiseido without interruption. I'm struggling to find something that is also enriched and hydrating. This serum isn't bad. It is hydrating. I bought whole line I will report back in a month

If you didn't figure it out yet, I LOVE this Hyaluronic acid. Actually I love all things COSRX. Ive been using their products for a few months and I can tell a difference in my skin and I'm starting to get compliments from my sisters and friends that my face looks smooth and bright! I didn't have any acne or anything just wanting to age gracefully and I think this is truly helping. Its a thick serum and it feels lovely when you put it on. I keep all my face potions in the fridge so putting on a cool serum makes it even nicer.

3.0 out of 5 stars Only last me less than 1 month

Hardly any liquid inside. I have my usual routine, and included this also, but it didn’t last that long. I’ll just stick with my basic routine, because this didnt add extra benefit, and with such small amount in a bottle.

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.

My wife loves this product, expensive and the bottle should not be black. There is no way to see what is left in the bottle until it’s empty then it’s too late. She subscribed for 6 months but had to revise it to 90 days, didn’t last too long. Price had also increased since we last bought it

1.0 out of 5 stars No product in the bottle.

I own the very same bottle in the retinol love it use it nightly. This on the other hand came virtually empty lasted a week. There is very little product in the bottle. Save you money and buy another no way the description of amount is correct. I looked on the bottle and could find the amount displayed.

A great humectant, hydrates well, don't expect anything else.

Less then half serum

A.I. · June 4, 2024

My wife loved this so I reordered, the second time it shocked my wife as she complained that it didn't last even half the time as before. The product lacks serum quantity visibility. Not happy to continue.
