I'm currently using my nth bottle of this product. Among various vitamin C products, this is the one I've settled on. I believe antioxidant products are essential in your 30s, and I was specifically looking for one that combines pure vitamin C, ferulic acid, and vitamin E. Initially, I was hesitant because the brand name seemed a bit... well, small-time and childish, to be honest. However, the fact that it's manufactured by Kolmar Korea, and the ingredients and their concentrations are clearly listed, convinced me to make the purchase. In the end, I'm consistently using it because I'm satisfied with its absorption speed, how it applies, and the price. It's sold as 15ml, 1+1, but I essentially view it as paying for 30ml. Since vitamin C products need to be refrigerated after opening and used quickly within their shelf life, I think this packaging is quite suitable.
Cons
I've tried many functional ampoules, but this one is the stickiest by far. Usually, when I finish my routine naturally with a cream, it absorbs into my hands without leaving a sticky residue. This one, however, always leaves my hands feeling sticky. Also, due to the nature of its ingredients, it has a very short shelf life, and storing it in the refrigerator is quite a hassle.
Tip
I understand that vitamin C is known to be a tricky ingredient to work with. When you're unsure about a brand, it might be a good idea to check who the manufacturer is before making a purchase.

Positive points: - I have dry skin, but when applied with the dropper, it glides on smoothly. - It absorbs quickly and leaves my skin feeling incredibly supple. - I've tried various vitamin products, but stubborn marks remained. However, with this innovative vitamin serum, those areas are starting to fade. The high concentration of pure vitamins seems to deliver rapid results.
Cons
Room for improvement: - The quantity is small... But as with most high-quality, expensive cosmetics, I think the pure vitamin content at this price point is quite generous.

I bought this on a 1+1 deal from Naver and I've been using it ever since. I'm not sure if it's just me, but I use about 6 drops each time. I bought it in February and I'm still using it now in April, haha! It seemed a bit pricey for such a small bottle, so I've been using it sparingly, but it's genuinely good. Of course, being 20%, you really need to use it carefully. It does sting a bit, that's for sure... I also use The Ordinary and retinol. Fortunately, the retinol doesn't irritate me much, but The Ordinary really stings, so I have to alternate them carefully... haha. I apply this morning and night. They say you should apply Vitamin C in the morning too, so I'm trying not to skip a day. I'm diligently applying sunscreen and taking care of my skin, and I can definitely see my complexion has brightened! Before, my skin tone was uneven, I had dark circles, and my complexion was dull and dark. But these days, I can mix shade 10 and 15 concealers and it looks natural. Of course, I'm also using this with glutathione and niacinamide serums because I heard they're good. It's been two months since I started using it, and I plan to keep using it. I realized the importance of brightening after turning 25. I think anything rated over 4.6 on Hwahae is worth trying.
Cons
There's nothing bad except for the stinging... but that's to be expected with 20%. If it didn't sting, it would probably be a fake Chinese product. Give it a try!
Tip
Even if it stings, I recommend applying it right after toner or putting on a thin layer of another serum before using this. It's important to help it absorb into the skin quickly. And sunscreen... please apply it very carefully. If you don't apply it properly, the vitamin C could cause darkening. You really need to be careful in the morning, haha. Oh, and I also recommend looking into other brightening ingredients like glutathione or niacinamide to use together. It seems to be more effective when used in combination. And don't use as little as I do - use a bit more. Other people say they see their complexion brighten more noticeably when they apply it generously.

It absorbs well and has excellent application. Suitable for all skin types.
Cons
It might cause a tingling sensation when first used, so it's best to apply it over another product initially.

It's so good. The usage feels so nice that I wonder if it really is a high-concentration vitamin C product. I wonder what kind of technology this is♡ I want to keep using it
Cons
There isn't one. It's over 20 characters, you know. Really, there isn't one. OMG.
Tip
Vitamin C should always be stored in the refrigerator. It doesn't discolor at all and stays nice and cool. Just wash it and put it straight in the fridge, haha.

Recently, I've been experiencing small pimples and increased oiliness. I've stopped using the Estrada cream I've been using for years and have been searching for other skincare products. I heard that a vitamin C ampoule helps with whitening, small pimples, and anti-aging, and that it's a good value, so I purchased an innovative concept ampoule. It's only been 3 days, but there's no irritation at all, so I've been diligently applying it morning and evening, even doing a double layer. (It does sting a bit on freshly popped pimples, but it's bearable.) I'm not sure if it's just in my head, but on the first night after applying it, I felt like my skin texture became smoother the next day. The small pimples also seem to have calmed down. It'll take some more time to see the full results, but I'm hopeful.
Cons
It is inconvenient to store in the refrigerator, but I understand that it is unavoidable due to the ingredients. The sticky feeling is uncomfortable. I'm not sure if I'm sensitive to touch, but I don't like the feeling of my hair sticking to my face. I don't think I can do double layering, even though they say you can get used to it.
Tip
On the first day, I applied the vitamin C serum after toning and followed it with a moisturizer. I didn't experience much irritation, so the next morning, I started applying it right after cleansing. I read that vitamin C is water-soluble, so you should leave a bit of moisture on your skin after cleansing and then apply the serum. (Personally, I find that a little bit of moisture helps the serum spread more evenly.) I apply it in the morning and finish with sunscreen. They say applying it in the morning is better for antioxidant protection. Next, I'll try retinol, and then I might give the Laneige Radian-C Cream a try.

I'll use this and if there are no major issues going forward, I plan to settle with it. I've been using those so-called 'Vitamin C ampoules' that don't actually contain any vitamin C, but only niacinamide. After using a real vitamin C ampoule, I can really tell the difference.
Cons
My skin is very irritated. It stings and something has come up on my face, so I only use it when my skin is in good condition.

The pores seem to have tightened, and there's a bit more elasticity - I like it.
Cons
When my skin condition is poor, it's really painful and difficult to apply it.

I'm currently using the second bottle after finishing the first one. I tried the Cosrx Vitamin C Serum a few months ago because I heard it's great for antioxidation. The Vitamin C serum is relatively affordable, so I thought I'd try it even if it didn't suit my skin - I could just throw it away. I was a bit worried and hopeful at the same time because I heard the Vitamin C serum can be a bit irritating, and my skin type is very sensitive. The Vitamin C concentration is over 20%, so it was a bit irritating at first - a stinging and tingling sensation. But I persisted and used it for a few weeks, and my skin gradually got used to it, so it wasn't as stinging anymore. After using it for a few months, it was fine except on days when my skin was extra sensitive. So I thought my skin had adapted to Vitamin C, so I tried switching to a serum with an innovative concept that's also good for the ingredients. But surprisingly, it was even more stinging when I first applied it, even though the Vitamin C concentration was similar to the Cosrx one. I thought I absolutely couldn't use it, but since it was expensive, I persevered and used it for over 2 weeks, and it gradually got better. Now, there's just a slight tingling sensation at first, but it subsides in 2-3 minutes. It seems the initial stinging sensation of Vitamin C serums doesn't last as long as irritation from Vitamin A or other active ingredients. If you want to try Vitamin C serums, keep this in mind and give it some time to adjust.
Cons
Vitamin C serum does tend to be somewhat irritating, and it needs to be stored in the refrigerator and kept away from light, as it can spoil quickly. Additionally, it comes in small bottles that get used up quite fast, which can be a bit of a hassle.
Tip
According to dermatologists on YouTube, it's better to apply vitamin C serum and then wait a bit before applying moisturizer or cream, rather than putting on the cream right after the serum. They say that simply applying a cream to raise the pH of the skin acidified by the serum is meaningless. The recommendation is to apply the serum, let it absorb for a bit, and then slowly apply the moisturizer.
