I was an avid user of the Triple Hyaluronic Ampoule, and was excited to try this new product. You get only half as much product for the same amount of money. It lasted literally only 2 weeks, even tho I used the exact same amount every day as I did the Triple Hyaluronic Ampoule (which usually lasted me about 6 weeks). I don't know wtf is up with that. Not to mention, the quality is like....just the same? It's not any better than the other one, and costs so much money relative to the original, I honestly don't see the point. I'm going back to the Triple H Ampoule from here on out.

I received this for free after filling a survey, and have been using it every morning. I layer rose water under and over it to maximize the liquid the hyaluronic acid can absorb, and it almost feels like a gel moisturizer by the time I'm done! That all said, if you are only looking for one product with hyaluronic acid I think that COSRX's snail mucin line is the tiniest bit better, but for those who don't like those products for whatever reason this is definitely a near-equal alternative!

I just finished my first bottle of this serum and I really love it! It's my first hyaluronic acid serum and I am hooked. I really liked the feel of this serum, it has a thick texture that feels luxurious and makes my face feel really smooth. I like that it also has ceramides. I think it helped reduce the redness of my face. Overall I enjoyed using this serum even though it is pricey for the amount you get. I used this in the morning. The other Cosrx products in my routine are the snail mucin essence and cream.

Love it! But firts thing first, I was really excited when I saw COSRX launching HA serum, because such product was missing in their line. The HA 3 serum is simply great! The consistency is in the middle between watery and thick one, and fells very gently on the skin. I appreciate that the product is scentless. I have very sensitive skin, using this twice a day and it does its magic. My skin feels nicely nourished and hydrated and bright. I definitely recommend to try this product to everyone. You can’t go wrong with HA in your skin routine.

I haven’t tried a hyaluronic acids serum before, and I was given a bottle to try for survey participation. I mostly use Cosrx products in my daily skincare regimen, items from the snail and cica collections.

I have to say, this serum is amazing. I have sensitive, combination skin that’s also prone to redness (fitzpatrick skin type 2.) Using it twice a day with the rest of my regular regimen has almost eradicated any redness, smoothed my skin texture, and seems to have balanced my oily and dry zones (hormonal breakouts notwithstanding.)

If you haven’t tried a hyaluronic acid serum yet, DEFINITELY try this one. My stupidly sensitive skin is totally happy with it and looks even better for it. 10/10 have already recommended it to everyone I know!
