Pros
I was worried it might be too thick due to its high hyaluronic acid content, but it absorbs well and has a great texture. Even with my oily skin, it was perfect for winter use. I think it would suit all skin types!
Cons
There wasn't anything I disliked about it. I definitely plan to repurchase.

Pros
It does pack in hydration quite well, though it's a bit of an odd, tight feeling. The absorption was good and it felt lightweight. For my dry, blemish-prone skin, it somewhat helped prevent those tiny bumps. Does it warrant a strong recommendation? To be honest, I wouldn't go that far.
Cons
As mentioned, the hydration feels uncomfortably tight. With use, you'll notice something forming around the opening. The stretchy texture means it gets all over the tube's mouth.
Tip
It worked best when applied to areas with tiny bumps. Those who enjoy a stretchy texture might appreciate this.

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
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
It spreads well, doesn't feel sticky. It absorbs quickly - a must-have lotion! It's an essential ingredient for dry skin, and it works great for me!
Cons
The price... the capacity... Indeed, it's disappointing when the price holds you back, even though you feel it's good.

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
This product provides immediate moisture supply to the skin and is particularly effective for dry skin. The highly concentrated hyaluronic acid ingredient is deeply absorbed into the skin, keeping it moisturized without stickiness, which is an advantage. When applied to the skin, it provides an immediate sense of hydration, and with continued use, the skin's elasticity and moisturizing power are improved. It can be used on sensitive skin without irritation, making it suitable for a variety of skin types. Additionally, its strong moisturizing power is useful for preventing dryness in the winter, and it also has the effect of softening the skin texture.
Cons
The price range may be somewhat high, and the lack of fragrance may be disappointing for those who prefer scented products. However, as a product focused on moisture supply and skin hydration, it is a serum that can be recommended for people with dry skin.
Tip
Use immediately after toner: If you apply the ampoule right after cleansing and toning your skin while it's still damp, the absorption rate will be higher. Applying products to moist skin allows them to penetrate more deeply, and the moisturizing effect will last longer. Concentrate on nighttime care: Using it at night allows your skin to better absorb the product, and the moisturizing benefits are maximized as your skin regenerates during sleep. Especially in dry winter conditions, apply a generous amount before bed and follow up with a cream for best results. Mix with other products: Hyaluronic acid ampoules pair well with other moisturizing products. For example, mixing it with a nourishing cream or oil allows you to address both hydration and nutrition simultaneously. Adding a drop of ampoule to your cream or oil creates a more luxurious, effective application. Store in the refrigerator: Using a chilled hyaluronic acid ampoule can have a soothing effect on the skin. After refrigerating, applying it - especially to reddened or irritated areas - provides a refreshing, immediate calming sensation. Use on neck and décolleté: Don't limit the ampoule to just your face; applying it to your neck and décolleté (chest area) can help keep that skin soft and supple. Regularly caring for these areas maintains healthier, smoother skin overall.
