Pros
Used for 3 evenings in January 2025 Skin type: Combination leaning towards dry, super sensitive skin, prone to allergies and whiteheads Rich texture that doesn't slide off. Absorbs moderately - feels a bit sticky after application, but this sensation fades over time. Leaves a slight glow on the skin after use.
Cons
Disappointing to see many ingredients that may irritate sensitive skin. Despite positive reviews, I decided to try it, but unfortunately... Experienced skin irritation with itching and stinging after application. Overall skin redness and allergic reaction occurred. On the third day, my skin felt so irritated that I had to quickly rinse it off with cold water without cleanser. Applied my usual soothing cream thickly like a mask before bed. The next day, small red bumps appeared, so I applied a skin ointment and discontinued use after using it for only 3 evenings. The dropper is too short, requiring two pumps to dispense enough product. The black container makes it impossible to see how much product is left.
Tip
This seems better suited for those with relatively healthy skin rather than sensitive, problematic skin. My sister, who never has adverse reactions to skincare, used it without any issues. However, considering age and season, she did find it a bit drying.

Pros
I keep frowning and my forehead wrinkles are also increasing. Let me summarize it briefly. ❤Texture: It has a slippery texture, but the absorption is fast, perhaps due to the dryness. ❤Viscosity: It's a viscous product. ❤Fragrance: It's fragrance-free. ❤Color: It's a transparent color. ❤Moisturization: The absorption was fast and good when I first used it, but the dryness came back day by day. I used it until the last day of the review, but this evening I went back to the serum I used before. Even so, the reason I recommend it is that there is nothing like hyaluronic acid for dryness.
Cons
The absorption was fast, but after applying all the basic skincare products and some time passing, my skin would feel a stinging sensation.
Tip
These days, I'm trying to avoid skin irritation, so I'm refraining from using toner pads. But when I use toner pads or just pat the toner, I mix a small amount of serum into the toner, which makes it easier and faster to absorb, and then applying the serum alone one more time works better. The attached photos are in order: The product as it was delivered. Product description on the back of the single box. Photo of the main product. I took a photo of the top lid because the shape is unusual. The serum texture on the back of my hand. After applying and absorbing the serum.

Pros
👍 It's gentle. Due to the mask, the skin around my cheekbones was a bit irritated, and when I used other products, it would sting a little, but this one was fine. The ingredients themselves don't seem to be too irritating. 👍 The dropper is convenient. It's easy to apply one drop at a time. The formula itself also doesn't feel heavy, which is nice. 👍 Completely fragrance-free.
Cons
👎 My skin has become weaker due to my menstrual cycle, but when I used other products, I didn't get as many pimples as I did with this one. After using this, I got quite a few pimples, especially on my forehead. 😢 They were just small pimples, but they were still bothersome. There's dimethicone in the ingredients, so I suspect the silicone ingredient may have clogged my pores. Even though there are other good points, the fact that I got pimples is a really big downside, so I can't help but give it 2 stars.. I might try using it again in the winter, since it could be because of the summer weather.

Pros
I am a woman in my early 30s with dry skin! Even in the summer, I apply ampoules and creams, as I have severe dryness. However, this serum alone was able to provide adequate hydration. The moisturizing power seems really great! 👍 At first, it felt a bit sticky, but it became fine as time passed. Applying this gives my face a slight glow.
Cons
- The dropper is too small, so I have to pump it at least 2 times or more to use it. - I experienced a bit of breakout on my face.

Pros
Ever since I caught COVID-19, my skin has become much drier for some reason. It's to the point that people around me can notice it. I've tried using various moisturizing ampoules, but I've always felt dry, and around 2 PM, I would strongly feel my skin tightening. But after using this product, the dryness symptoms have significantly decreased. I use the products in the order of Skin - COSRX Hyaluronic Acid Ampoule - Whitening Ampoule (sometimes I apply it, sometimes I don't) - Moisturizing Cream. Even after arriving at the office around 3 PM, I don't feel my face tightening anymore, and these days, I don't even reach for my trusty Gahee Multibalm that I used to apply religiously. (Other employees are going crazy with Multibalm and mists because of dryness) My skin is prone to breakouts, but I haven't had any trouble with that, and the formula is not too watery or too thick. As long as it doesn't cause any breakouts and it significantly helps with dryness more than other moisturizing ampoules, isn't that enough for a moisturizing ampoule? I usually write all sorts of things in my Hwahae reviews, but for this product, I don't know what else to say. I plan to continue using this ampoule.
Cons
How am I supposed to write 20 sentences when there's nothing to say? Ah, when the package first arrived, there was some white powder-like substance all over it, so it was a bit of a hassle to wipe it off and start using it.

Pros
My skin was extremely sensitive and prone to irritation, and I had tried many ampoules, serums, and creams, but this one felt refreshing and non-sticky, and absorbed quickly. The tightness in my skin has also significantly improved.
Cons
Although I used a lot of it, the quantity was too small and I've already used it all up. While the tightness in my skin improved with consistent morning and evening application, I experienced some breakouts and my face felt a bit irritated.
Tip
It absorbed quickly, and the dropper was short, which was good for my very dry skin. I used it twice in the morning and four times in the evening.

Pros
I was selected as a Hwahae Trial Reviewer and will leave a review after using the product for about 3 days. I have thin, sensitive skin and even using a little bit of irritating cosmetics can cause breakouts on my combination, sensitive skin. To be honest, I checked the ingredients after being selected as a Hwahae Trial Reviewer and found that there were a few ingredients that tend to irritate my skin. So I was hesitant about whether to use it or not, but I decided to try it out. My skin seems to have become smoother and more velvety. And since it contains hyaluronic acid, my skin has a subtle glow after application. I only use a toner and a moisturizer, but using the serum in between makes my skin feel much more hydrated. I'm not sure how it will work in the winter, but it seems like a good serum to use in the summer. If it doesn't cause any breakouts, I'll likely repurchase it after finishing the product.
Cons
Today is the 3rd day, and a reddish something has appeared on the right side of my cheek, so I think I'll have to stop using it for now. It seems that whenever the ingredient stearic acid is included, it causes breakouts for my skin... It looks like this product is still too irritating for my skin. But it might be a good serum for those who don't have sensitive skin.
