Although there was a slight stinging sensation when I first applied it, as my sensitive skin is prone to dryness, I quickly adapted after using it for a few days. When I looked in the mirror the next morning after first using it, I thought my complexion looked brighter, but I wasn't sure if it was just my imagination. However, as I continued using the product, the whitening effect became increasingly noticeable, and I have now repurchased it for the nth time. I recommend it.
ConsI have thin and sensitive skin, so similar individuals may experience a slight stinging sensation when using this product for the first time.
TipIt may take a bit of time for it to be absorbed, and if you apply it in the morning, you must absolutely!!!! apply sunscreen as well. It's best to leave a little gap so that it doesn't smear. Apply the next step after it has been fully absorbed.

The high 23% concentration meant that there was a slight stinging sensation the first time I used it. On sensitive days, my skin would appear slightly reddened, but after about two days, I got used to it. The serum has a thin, lightweight texture, and leaves a slightly oily glow when applied. The absorption is faster than expected, and I was initially a bit surprised by the greasy feel. However, when I apply it at night and wake up in the morning, my skin looks brighter, and I can definitely see an improvement in my remaining spots and dull complexion.
ConsThe oxidation is quite fast. It seems like it needs to be used up within 2-3 months after opening. (Refrigeration is essential!) For sensitive skin, the stinging sensation may be a persistent concern. Those who dislike the sticky or oily shine after application may find it uncomfortable. However, considering the price, it is quite a decent product among the high-concentration pure vitamin C products in terms of ingredients and effectiveness. Especially for those concerned with blemishes/tone improvement, consistent use may result in quite satisfactory changes. (However, for those new to vitamin C serums, the concentration may feel too high, so it is recommended to start with a small amount cautiously!)

However, it did not cause any irritation or redness. We recommend starting with a lower level and gradually adapting your skin before using it.
ConsThe concentration was a bit too high for me, so it stung a little. First of all, it was a product with particularly poor absorbency. It was too sticky, and even when I applied a cream on top, it was seriously sticky. Also, it was a highly acidic vitamin product, so when it touched other areas, it felt like it was leaving a yellowish residue.
TipVitamin products are easily oxidized, so it is recommended to open and use them within two months. It is also recommended to store them in a cool place away from direct sunlight.

Reviews by The Hwahae Testers undergo the same strict verification process as regular reviews, and if they don't meet our standards, revisions will be requested.ProsMy skin type is dry, sensitive, and atopic. This is an honest review after using the product for over a month! ✔️ Texture: The texture is like a slime with a lot of moisture! It flows down smoothly and you need to spread it quickly. ✔️ Absorption: It's good! I can feel it melting into my skin right away. But after it's absorbed, my skin becomes very supple and sticky. Haha. I don't really mind the stickiness, but for those who dislike it, please keep that in mind! ✔️ Effectiveness: This is the first time I've used a whitening product that's this effective. Other products had minimal brightening effects, but after using this consistently for 3-4 days, both day and night, I could clearly see my skin tone becoming clearer and brighter!👍
ConsThe feel of use: After using it, my skin feels irritated... It's especially worse on days when my skin condition is not good. I usually always feel some irritation, though it doesn't last long. After applying the cream on top, it gets better! Repurchase intent: I do have the intention to repurchase... There are some downsides, but this is the first time I've encountered a product with such great effects 😂 I think I'll have to keep this one...haha
TipIf you dislike the sticky feeling on your skin after use, apply a cream with an oily texture on top. This will help absorb the excess moisture, leaving your skin feeling plump and bouncy like jelly. Hwahae Trial Reviewers recommend using it only 3-4 times a week, applying about 5-6 drops. While the effects may not be as dramatic, this helps minimize skin irritation. I initially used it daily, but have since increased the time between applications.

But it absorbed quickly into my skin. ✔Pore elasticity and skin texture improvement I only used it at night, and when I washed my face in the morning, I noticed that there was less oil buildup and my skin felt smoother without any bumps.
ConsAbsolutely do not shake it for use. I didn't read the manual at first and shook it to use it, thinking it would erupt like a lava explosion... It was a disaster. Pure vitamin C is easily oxidized, so it's a bit of a hassle to refrigerate it for use, and the shelf life is relatively short, but other than that, I used it with satisfaction. When you have trouble or your skin condition is not good, it stings a bit.
TipAfter using the vitamin ampoule, sunscreen is essential, so I used it only at night. The formulation itself also leaves a sticky feeling, so it seems more suitable for nighttime use. Don't forget to keep it in the refrigerator and use it properly.

It also has a whitening effect, which I like.
ConsIt may sting a bit, and once opened, it should be used quickly, so it seems like it needs to be used carefully.

I loved how it bursts and gets immediately absorbed, and I was looking for a watery, fluid formula - I found exactly what I wanted.
ConsSensitive individuals may require an adjustment period. The skin can feel a bit stinging, and the formula is quite watery, so if you don't apply it quickly, it tends to drip down.
