Pros
With 3% hyaluronic acid, it really locks in deep hydration
Cons
The strong sour smell and sticky texture are quite noticeable. I guess it's because of the high hyaluronic acid content

Pros
I've been using this for about two weeks, and it seems like a great product when used correctly. It provides excellent hydration and definitely helps combat dryness when applied.
Cons
Probably because of the hyaluronic acid, it feels a bit more uncomfortable if it gets into your eyes.

Pros
This is the first time I've tried it, but it definitely seems to have better moisturizing power than other regular serums. I'm using it well.
Cons
There's really nothing disappointing. If I had to find something, it would be the price...?

Pros
During the winter, my skin became very dry, so I was looking for a product. I ended up purchasing one out of curiosity because it was a good price, and the ingredients were reassuring. It's a serum with a fairly high viscosity, and it applies smoothly. As soon as I apply it, my skin starts to glow. The tight, dry feeling on my face has significantly diminished. I'm very satisfied!!
Cons
The product was good, so I tried to add it to my cart again, but the product information is no longer available.
Tip
You'll feel your wrinkles smoothing out, so apply the product by gently massaging in the opposite direction of your skin's wrinkles.

Pros
When I woke up and applied it, I definitely felt a bit more moisturized the next day. I'll have to apply it a few more times, but I hope my skin will be less dry.
Cons
It seems like you should apply it generously. A little bit at a time won't show.

Pros
It is definitely moisturizing. I've tried many ampoules, but when I use this product after applying the booster serum, the dryness seems to be much better controlled. I purchased it during an event for 3,000 won, and I feel I got a good value for the price.
Cons
There are no particular drawbacks that come to mind, but it would be nice if there was one more lid for the courage container.

Pros
Now is the perfect time of the year. Since the winter is so dry, applying it twice before bed and then sleeping is so nice the next morning.
Cons
The price is too expensive compared to the capacity. Unless it's on sale, I can't even consider it. ㅠㅠ
Tip
Applying the mask pack in overlapping layers is so wonderful.

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.

Pros
The slightly runny viscosity means it doesn't immediately drip off, and when applied, it feels moisturizing. This is one of the products I feel I purchased well, as it seems to have a decent level of moisturizing power after I apply toner and serum.
Cons
While it's been fine so far (after 2 weeks of use), the dropper is a bit short, so some users have reported feeling inconvenienced when trying to use the last of the product. I'm a bit concerned about how to use it properly in that situation.
