Pros
The overall tone seems to be getting brighter. There are still freckles. I'm not sure if the blemishes are fading, but after using it for about 3 weeks, I feel like the tone has improved. I don't find it irritating, so I sometimes use it alone, but it's quite sticky, so I always apply a cream as well.
Cons
The stickiness and the metallic smell that comes out as it dries are the issues. Since it's a vitamin serum, that's probably why. That's why I apply it with a cream.

Pros
This is a review after using the product for ten days. The positive aspect is that my skin tone has become noticeably brighter and my blemishes have faded. I have relatively clear skin without freckles, but as I entered my early 40s, some sporadic blemishes started appearing, and those have faded.
Cons
The downside is that, even though I store and use it in the refrigerator, some granular particles seem to form around the cosmetic glass case during use. And when I use this product alone, it feels quite irritating.
Tip
When I mix this product with the vitamin E cream from the same manufacturer, it becomes less irritating and much smoother to apply. It gives a coated feeling to the skin, and when I wake up in the morning, my skin feels smooth and my skin tone has improved even further! So far, I'm very satisfied with the product. Even though I have combination skin with dryness, I don't feel any tightness or pulling, unlike some other reviews. I think I will continue using this product.

Pros
It's amazing that I don't feel any irritation at all. I was planning to only use it at night if it was irritating and stimulating, but there's none of that, so I've been using it during the day too haha. There have been no breakouts from this product. The weather has been very dry lately, and until yesterday, my cheeks were getting drier as the day went on, but that's a bit less now. And my pores seem relatively calmer than before using it. It feels more tamed :) It also seems to be helping with skin texture and tone recovery. For the past 2 years, I misunderstood my skin and used acne-focused basic skincare, and recently experienced allergic reactions to the oily/trouble-focused products... I went to a dermatologist and got a lecture, though not really a lecture haha, and got a prescription that helped me recover. Anyway, after those 2-3 days of confusion, I realized my skin is more combination/dehydrated/sensitive, so I need to find gentler, more moisturizing products. It seems the real issue was lack of moisture. (I also just learned about the Hwahae app this time - my younger sibling couldn't believe I didn't know about it before. I used to use Etude House products when I was younger, but became a skincare nomad after studying abroad.) Anyway, I learned about this product through an acquaintance, and the ingredients looked good and seemed helpful for skin recovery, so I tried it. The conclusion is that I'm satisfied :) However, I haven't used it on the trouble spots on my forehead or right cheek that are still recovering. I'm only using it on the left side of my face (excluding the eye area and down to the cheek) where the blemishes have healed into scars. I've learned the hard way that you have to be very careful with functional cosmetics.
Cons
The fact that it's refrigerated is not a problem at all, and everything else is fine! The one thing I'd point out is that after using it, my skin feels a bit tacky and sticky, and I have to follow up with a moisturizer. The ampoule I'm using for my oily skin is only applied to my blemish areas, and that one doesn't leave a sticky residue on my hands afterwards, so in comparison, that's the one area where this product differs.
Tip
While they're not exactly groundbreaking tips, let me list the other products I'm using in conjunction with this one. As a 30-year-old with workplace stress and going through seasonal changes, I mistakenly thought my skin type had shifted from dehydrated to more oily, and had been using products accordingly. But after the recent confusion and struggles, I've finally found my way back to understanding and caring for my healthy skin. A.C.N.S Foaming Wash -> Dr.D Cleanser A.B.N Thermal Water Mist -> Dr.D Toner (wipe-off) (This one hasn't been a problem at all) A.C.N.S Essence Lotion -> This product & Cer.T.D Burning Ampoule 1•2 (I'm applying the two products to different areas, and plan to switch to just this product once the blemishes clear up.) A.C.N.S Derma Relief Recovery Cream -> Pha.R.S 17 Cream I've abbreviated the brand names just in case it comes across as an advertisement. If your skin suddenly becomes problematic and it's not due to hormones, I'd recommend visiting a dermatologist before trying new skincare products!

Pros
Even though the effects may not be immediately noticeable, comparing before and after application, there is a difference. My skin tone appears a shade brighter. It glides on like water and once absorbed, leaves a supple, bouncy feel. The dropper applicator is hygienic. While there is a slight stinging sensation, if you are looking for even a small improvement in brightening and firmness, I would recommend this product.
Cons
It stings quite a bit. I'm not sure if 'stinging and pungent' is the right way to describe it, but the stinging sensation does not subside even after repeated use. It takes around 10 seconds for the irritation to calm down.😅 The requirement to refrigerate it is an inconvenience. If the bottle opening is not cleaned thoroughly, the hardened vitamin-like granules can make it look messy.
Tip
During sensitive periods, the area around blemishes tends to sting more, so it's best to use just a few drops of the cream in those spots.

Pros
I had been switching products consistently, and this is the second bottle I've used. It's a vitamin C serum, and while it's not dramatically moisturizing, it has made my skin tone brighter.
Cons
There is an unavoidable stinging sensation, and the bottle's nozzle area has become clogged and hardened, which is inconvenient.

Pros
I have sensitive/dry/acne-prone skin type. I ordered it after seeing it on YouTube, and I've been applying it consistently in the evenings for just over a month now. ✔ Brightening effect I used it hoping to fade acne scars, but I'm not sure about the effect on the scars, but my skin tone does seem to be getting brighter. ✔ Plumping effect When I apply a few drops and let it absorb, my skin feels plump and bouncy.😊 ✔ Slight tingling, but it's tolerable ✔ Seems to suit my skin well, so I plan to repurchase after finishing this bottle.👍
Cons
✅ Refrigerate I was told to refrigerate the product after receiving it, so I've been storing it in the fridge and using it, but it's a hassle.😟 I sometimes forget, and it's just annoying. ✅ Don't apply to blemishes or broken skin It stung really badly, so I was surprised!🥺 Be careful!
Tip
✅ For those who may experience intense tingling or irritation, trying mixing a drop or two of the cream into your regular moisturizer could help reduce the sensitivity.🤗

Pros
It's a heavy moisturizer, but it's great in the summer and essential with cream in the winter. I bought it because it has a lot of vitamin ingredients and the ingredients and price are good. After 2 weeks of use, my skin tone seems to have brightened and the spots have faded. It has almost no scent and is a slightly yellow, flowing liquid. Week 4: There is sometimes a stinging sensation, but it soon goes away and my skin feels a bit brighter. The spots also seem to have become more blurred.
Cons
There are no disappointing points, just that the design could be a bit more simple and sophisticated.
