Too Watery

There were no particular disappointments in using it, and it was good.

I felt my skin became brighter, the price was affordable, and it was gentle, so it was nice to use.

하이퍼 비타민C 23 세럼

It was a bit disappointing that the whitening effect was not strongly felt.

My skin had no trouble, and it absorbed quickly, so I was pleased.

There are no major drawbacks, but there is a slight stickiness.

The product has a high vitamin content and low irritation in proportion to the content, which is good.

There are no regrettable points. It is slightly sticky, but that is the characteristic of high-vitamin content products, so I will accept it.

It has a high vitamin C content and is non-irritating in proportion to the content.

It seems to have a strong vitamin content, so it might be effective, but it's sticky and I end up not using it often.

The sticky texture makes the user experience a bit unpleasant. It's an inconvenient user experience :(

Extremely fast discoloration and browning🥲
This product discolors much faster than other products, so it's necessary to refrigerate it for use. I've used various vitamin C products with concentrations ranging from 10% to 23%, but this is the first one that discolors so quickly. It turned bright yellow so fast that I just threw away the remaining product.
Once refrigerated, the product needs to be kept refrigerated until the end of use, so I usually store and use it in a cool, shaded area, but this product definitely needs to be refrigerated.

The irritation is not too strong compared to the concentration (similar to other products)
The watery formulation makes it easy to use in combination with other skincare products
The brightening effect is not dramatic or slow, but effective
Affordable price relative to the concentration

The cost-effectiveness is a bit disappointing. But I'm glad I saw good results

It was a bit sticky, but it worked well. Good effect

I just realized that even if the ingredients are gentle, they may not suit my skin.

But after using this, I don't know why, but I keep getting breakouts...

There is definitely a feeling that my skin becomes brighter and more radiant in the morning after using it.

I'm completely satisfied, so it would be even better if the price was a little cheaper.

Since the pure vitamin C content is high, you can use more vitamin C per volume.

It would be better if I could check the remaining amount. :(

It's good. It has good spreadability and less odor compared to other vitamin products.

It is sensitive to sunlight, so it's better to apply it only in the evening when it's dark, not in the morning. For those who are sensitive when using it with retinol-based products, it's good to use them alternately every other day or more.

It may sting and cause irritation, so adjusting the amount to suit your own skin is necessary.

It has good absorbency, whitening effects, and good cost-effectiveness, so I think it's a good introduction to vitamin C serum like me.
