The stimulation may vary from individual to individual, so try it once and if it suits you well, use it.

The vitamin content is not particularly high, which is a bit disappointing.

It's quite affordable and quite usable. If expensive ampoules are burdensome, I recommend it.

퓨어 비타민 C21.5% 어드밴스드 세럼

It's really sticky ㅠㅠㅠㅠ And it oxidizes quickly too, and sometimes it even arrives already oxidized... If you have any skin irritation, it can be painful.

This is the only vitamin product that I've seen real effects from! I live in the US and the other high-priced products never seem to work, so I thought it was just a waste of money. But when I tried this one, I was really impressed by the great value for the price, so I use it every single day.

Although it's not sticky, there is a slightly stinging sensation. I use it together with a vitamin A cream, and it does tend to exacerbate peeling and irritation when applied.

I purchased it because of the high vitamin C content, and it definitely seems to be well-absorbed. It's not sticky or drying at all.

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.

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.

They say vitamin C absorbs better when used with vitamin E, so using a vitamin E cream or oil together would be a good idea.

There's really nothing disappointing. It's sometimes sold for around 22,000 won on the Naver Store, and if you buy it during a sale, the price is quite affordable.

The whitening effect is definitely there. I bought it to help quickly restore the reddish traces of acne, and it seems to have helped a lot in returning my skin to its original color.
The vitamin ampoule is also one of the effective whitening products I've tried, and that's because it contains 30% vitamin, so it oxidizes a bit faster. But this one has 21.5%, so the oxidation seems relatively slower. I kept it in the refrigerator and it didn't turn yellow for a long time, staying transparent. It did eventually turn yellow, but seeing it turn yellow means the vitamin content is good.
It's not too sticky to use, which is nice, and it pairs well with other products. I'm currently trying Pureador products, but if I'm not satisfied with them, I'll consider repurchasing this one.

When I apply it at night and go to sleep, the ampoule gets on my pillow or pajamas.

My skin seems to be glowing brightly. It wasn't irritating to me.

It stung a bit as soon as it touched my face, making me wonder if I made a bad purchase.

It feels very moisturizing! It absorbs quite well, better than I expected.

But I couldn't finish using it because it was too irritating. That's a shame... I think I used it for about a month. Compared to the Goodal product I used for a long time, I'm not sure if it was effective. My skin just became more sensitive... It doesn't seem to suit my skin type.

The product is hygienic and lightweight as it comes in a dropper. The application and absorption are good. It seems like it will last a long time as you don't need to use much.

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.

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.

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.

I'm not sure if the dramatic spot-removing effects are real, even after using it for a while.

I've been using it before bed every night, and my skin feels so soft and smooth the next day^^
There may be a slight tingling sensation on some days depending on my skin condition, but it's non-irritating and works great.

1. Scent
The chemical-like scent is not ideal, but it's not too overpowering.

2. Stickiness
It's definitely a thicker, gel-like formula, and I can feel it clinging to my eyes when I blink, so there is a bit of a sticky feeling.

3. Irritation
As I mentioned, it has that crawling, stinging sensation, but if you pat it in while distracting yourself, it helps. I'm trying to stay positive and think that the high vitamin content is the reason for this.

I recently started using a vitamin serum for the first time, and my skin felt a bit dull, so I decided to try it.
While I'm not sure about the moisturizing effects yet, I definitely feel like my skin is becoming healthier.
I'm not sure about the color change or if it's getting whiter.
They call it a 'wash serum,' but it's not as irritating as that sounds. It's more like a crawling bug feeling, you know? If I quickly apply a moisturizer and pat it in, it helps distract my senses and makes it a bit better.
