Even if you store it in the refrigerator, if you don't use it up quickly, it will turn brown and become sticky. That means the efficacy has diminished. Be cautious.

The product quality itself is not bad, but these days there are so many cost-effective products, so I'll give it 3 stars. I won't repurchase this product, as it costs almost 200,000 won (around $200) for the set with the Hydra B-5 Complex.

I struggled with adult acne until my early 30s, so I couldn't use moisturizing creams during that time. I've tried pretty much all the serums and ampoules that were considered decent back then. This product is said to work even better when used together with the Hydra B-5 Complex, which provides hydration, so I purchased the set at a high price and used them together.
At the time, the pure vitamin C stabilization technology wasn't as widespread as it is now, so while there were many vitamin C-containing products on the market, this was the only one that purely and powerfully delivered pure vitamin C without other ingredients mixed in. So even though it was expensive, I used it without hesitation. The product also has very little preservative, so you have to store it in the refrigerator to maintain freshness.
It does sting a bit on acne-scarred areas, but it's not overly irritating. However, the solution is so runny that if you don't spread it quickly, this expensive serum will just drip down your face, so I always had to be very careful when applying it.

하이 포텐시 세럼

I only used this and applied Avene sunscreen, and it was actually more moisturizing.
I applied the vitamin serum and was worried it would be drying, so I also used the Iope rich cream and sunscreen, but over time it actually got drier...

None, a bit expensive? It's a bit cheaper to buy it directly.

It's really great. The vitamin C from the long-established company is definitely the best.. I've tried various products like Iope, Ordinary, Isol, First C, and vitamin powder that you use less, and the more expensive ones are better. It seems to be well stabilized.. I can keep using it because it doesn't have a lot of unnecessary ingredients. The dropper is really unique. It seems like it will drip, but it never does and it's great. It stings a bit but it goes away in a few seconds. It's not too sticky and absorbs quickly.

I keep it in the fridge and apply it chilled.

The price, though... ^^ I do use duty-free, but I wish I could get it through home shopping like before. :(

I've been using this vitamin serum since my 30s. I've never found anything more effective than this. As with anything, you need to apply it consistently to see the results. ^^ I have oily skin, so I usually avoid anything oily, but this is far from oily and works great for me. There may be a slight tingling sensation from the purging process, but it goes away after a while. I recommend this to everyone, whether for pigmentation or brightening.

Since it's a vitamin serum, the effects may diminish over time, so don't be stingy and try to use it up within a month.

The price is a bit too high. It felt a bit drying on my dry skin, but using it with Hydra B5 helped. However, both products are a bit pricey.

I've been using it consistently for 3 bottles now. My face feels brighter and my blemishes have faded. Using it together with Hydra B5 seems to enhance the effects.

Apply it while allowing enough time for it to fully absorb.

At first, it may sting and surprise you.
Applying it and providing enough moisture is essential.

I tried using SK2 and it seems to have brightened my skin and helped with wrinkles a lot. I'm still using it and am satisfied so far.
It may sting a bit, but if you provide enough moisture, your skin will transform.

In my case, this product alone was slightly insufficient.
I had to use it in combination with other products.

I've tried using this as a transitional season item.
It's great!
For me, it has become an essential item to get through each transitional season.
It seems to work regardless of skin type.

The watery formula means that when you dispense it with the dropper, it just flows all the way down to your chin, which is a shame.

I had a lot of freckles, but after about a week, my skin tone definitely brightened up.

The price is too expensive :( 
You can only buy it once a year with a big heart haha

The yellow face has really brightened up
But the price is shocking
So I'll take off one star

In the winter, it gets quite dry, so I have to apply a moisturizer and face oil on top of it~

It's been 14 months since I started using it~I definitely feel like my complexion is brighter and my pores are a bit smaller~I love it^^ However, in the winter it gets a bit dry, so now I apply this product's cream, and then add a moisturizer 5 minutes later...I also use a face oil occasionally..Aside from being a bit dry in the winter, I love it^^

The color tends to turn more yellow over time, but if you store it in the refrigerator and use it, the color change will be much slower.

The price is a bit disappointing, but it's not bad if you use it during sales events. During sales, they usually have package deals, and the moisturizing cream, mist, and vitamin E ampoule are all good. When I switched to other products and then came back to this one, I felt a slight tingling sensation when I first applied it, and a slight itchiness, but after using it consistently, my complexion became brighter and my pores and skin texture improved within a few days. The initial irritation also went away.

Among vitamin C ampoules, this is undoubtedly the best!!
They say that stabilization technology is important for vitamin ampoules, and this one certainly has a strong brand value. You can feel the differentiated effects when you apply it. Even though it's expensive, when I tried other products and then came back to this one, I could really feel the difference.

It feels a bit drying to use in the winter and it tends to slide off, so you have to be careful when applying it.

I purchased it last year through home shopping channels, but I just now checked the ingredients through Hwahae. 
I feel more confident about it now and it's great to use in the summer.
