Pros
Wow, this product really made me realize what it means for skin to be truly hydrated... It's so rich and nourishing. I feel like my skin texture has actually improved after using this. Really good stuff!
Cons
It does leave a slightly sticky feeling, but that's about the only minor drawback I can think of.

Pros
I was pleasantly surprised when I logged into Hwahae after a while and they offered this product for just 3,000 won, so I ordered it along with the product I was planning to buy! Since I've been consistently using COSRX's Vitamin C serum, I trust the brand and didn't hesitate to purchase from their other lines as well. First off, it absorbs really well on my skin~ It sinks in smoothly right away and isn't sticky at all. After applying this product, followed by my Vitamin C serum and then a moisturizer, my skin stays hydrated until morning. While I'm not sure how it would work for those with very dry skin since my skin type isn't particularly dry, I'm very satisfied with it!
Cons
The product itself is good, but it's a bit disappointing that the container is so wide and large compared to the actual amount of product.
Tip
COSRX's Vitamin C serum would sometimes cause a tingling sensation, but when I apply it after this Hyaluronic Acid 3 serum, I don't experience that at all, which is great!

Pros
It's moisturizing without being sticky. The texture is light. I highly recommend it!
Cons
The amount seems a bit on the smaller side, but that's okay since larger sizes can get tiresome to use up.

Pros
The absorption and application are both excellent. You can immediately feel how moisturizing it is as soon as you apply it.
Cons
While it feels very hydrating right after application, it tends to feel relatively drier as time passes. I think this might vary from person to person.

Pros
The absorption was so good and it became moisturized quickly, so I was satisfied! I have dry skin on my hands, but the immediate moisturizing effect was satisfactory.
Cons
It only lasted for 2 weeks... ㅠㅠ The effects were good, so I wanted to use it diligently for a long time, but the price range is a bit high considering how good the product is.
Tip
Once the hyaluronic acid is sufficiently absorbed, apply a cream containing ceramides, cholesterol, and fatty acids on top to maintain moisture throughout the night!

Pros
The Cosrx line has a thicker viscosity than top-ranked hyaluronic acid, but it blends well and provides a moisturizing feel even with a small amount.
Cons
There's nothing.There's nothing.There's nothing.There's nothing.

Pros
The shape of the exterior is very luxurious. I like the matte black lid. And the dropper format makes it easy to use neatly. The serum's dropper format is certainly good. After applying the skin, the moisture is doubled when applying the serum and then the cream. I only applied it to the left side to compare, and the difference is clear. The serum has a slight stickiness, but it's a pleasant degree. The flow is not a steady stream, but rather a gradual dripping. It is easy to absorb.
Cons
While the size is a bit small, that could be considered a drawback. It would have been better if it was 30 millimeters.
Tip
It seems that pounding helps the absorption to become much faster and deeper. Tapping with your fingertips and doing acupressure also improves blood circulation, which is a two-for-one benefit.

The product feels very moisturizing and deeply penetrating. There is also less greasiness, which is great.
Cons
There seems to be a slight discomfort, but I don't think there are any notable issues with you at the moment.
