If I apply it consistently, it seems the dark spots are definitely fading, but I haven't noticed my skin getting lighter yet. I think I need to use it more to see the full effects.
ConsIt is extremely sticky. It's fine if I apply something like a moisturizer on top, but over time the stickiness comes back up, and it's a bit difficult with my hair sticking.
TipApparently, it's best to apply this as the very first step in your skincare routine. And it's said to be more effective when applied in the evening rather than the morning. Also, I'd recommend thoroughly absorbing it before applying your moisturizer. That's supposed to enhance the results.

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.

ConsThere is nothing particular. The smell is not very good. It's a bit too sticky... I'm not sure if it should be removed.

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.ProsHere is a review written based on the criteria of being in my 20s, having dry and sensitive skin, and experiencing flushing: My skin is very sensitive and goes through cycles of breakouts, so the reason I tried this vitamin C product, despite my sensitivity, is that my dark spots have become really severe. I started getting interested in skincare in my early teens, but I never properly applied sunscreen, so I ended up with freckles. Those freckles have been getting darker lately, which is why I decided to try this product. Texture: The texture is light and absorbs well. However, when I layer it a few times, it becomes quite sticky. Breakouts: I can't say I had no breakouts. There may have been some overlap with my natural cycle, but I did experience some stinging when applying it, and I would sometimes wake up with red, pimple-like bumps that would then calm down. When I apply it, those bumps do seem to come up, though I'll need to use it more to know if it's definitely because of this product. Scent/Taste: It's almost scentless, but when I apply it, there's a bit of an iron-like smell, kind of like the smell of coins that have been held for a long time. As for the taste, it's quite strong, so those who don't like sour tastes should avoid getting it on their lips.
ConsIt seems like there might be some drawbacks if I use it more. I don't really know of any major downsides yet. The only thing that bothers me is that it's a bit too sticky, I suppose?

I used up an entire container and feel like the fine lines have disappeared.
ConsRefrigerated storage is inconvenient and absorption is not very good. I'm not sure about the whitening effect, but it's sticky and my face turns yellow if I don't wash it.
TipApply the Hwahae and absorb it. Apply it once more to keep it moisturized. This will reduce stickiness and improve absorption.

The blemish care has shown a bit of effect.. it's a bit faded, I guess??
ConsI thought it would be irritating due to the high vitamin content, but it was even more intense than expected, so I switched to another product in the middle. There's a bit of a sticky feeling, and it seems a bit too irritating, so I feel like I'm getting a bit of a flush.
TipIt would be better to use the one with lower concentration first and try it out. I used it at night and tried to calm down any skin irritation with the soothing serum and cream.

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 oily and sensitive, and I often have breakouts and a lot of blackheads. In the past, I would aggressively extract the oil and blemishes, leaving behind terrible scarring. Even with makeup and photo editing, my skin looked so bad that others would comment on how gross it was. I happened to come across this product by chance and read the reviews, which said it was too irritating and didn't work at all, and that it was a waste of money. But I decided to try the 1+1 deal for 2 weeks, and I was amazed by the results - my friends said my skin looked like I had laser treatments, the marks faded or disappeared, and I was so grateful to COSRX for this product that was a game-changer for my long-standing skin insecurity. My whole face became brighter, and the marks on my chin faded. I'm not sure about the hydrating effects, but the whitening was very effective. I didn't really feel the irritation that others mentioned, except for a slight stinging when applying it directly on blemishes or freshly extracted pores. But applying it after toner/skin made it much less irritating. It's probably best to avoid using it when you have active breakouts, as the irritation could be more intense then.
ConsThe product has good spreadability, but due to its nature, it is quite sticky and tends to leave some residue. Although it absorbs well, there is still a sticky feeling on the surface, and despite this, I couldn't give it up because the effects were so good. I had this anxious feeling that I needed to stock up on it. In the case of this product, I didn't experience any breakouts or issues, but the lack of moisture was a bit disappointing. However, I would either apply an additional layer or use it before applying something else.
TipThis product should be applied with sunscreen, and it is recommended to apply it primarily at night rather than during the day.

For these vitamin C products, I recommend buying one and then purchasing another one after using the first one, rather than buying multiple at once.
ConsTo be honest, it feels a bit sticky after applying it.... That's why I don't feel like putting it on when going out.
TipCreating a slightly acidic state on the face and applying it helps with absorption, so I wash my face with a cleansing foam and apply it while my face is still slightly damp!
