It also seems to be quickly absorbed.
ConsWhen applied before sleep, it leaves a yellow stain on the pillow ๐ข And when applied by hand, it leaves a strong metallic-like odor on the hands.
TipIf you tend to toss and turn while sleeping, it would be a good idea to apply it in the morning or lay a dedicated towel on your pillow and sleep on it in the evening!

I don't usually have many blemishes, but my skin is thin and prone to fine lines. If my skin doesn't stay moisturized well, it dries out quickly, so I prefer a dewy finish. The most satisfying aspect of using this product was that my face looked brighter in the morning. After applying it before bed, my skin appeared clearer when I looked in the mirror the next day. It was more of a refined skin tone effect rather than an immediate whitening effect. Many vitamin products feel heavy or sticky, but this serum is lightweight and absorbs quickly, making it easy to use both morning and night without any burden. The reasonable price is also an advantage. Vitamin serums are often expensive, making consistent use difficult, but this product can be used comfortably without much financial burden. Since it's a product that requires consistent use to see results, I think choosing a good value option is important, and in that regard, I was very satisfied.
ConsVitamin serums are often expected to have an immediate whitening effect, but as seen in YouTube and Instagram reviews, it can be difficult to experience dramatic whitening results. Of course, using it consistently can give a sense of improved skin tone, but using it once or twice does not necessarily make the skin significantly brighter. Another disappointing aspect is that when the skin condition is not good, using the serum can cause a stinging sensation. As I have reddish skin, my face felt slightly flushed right after application. Fortunately, this subsides over time, but it's best to avoid using it on sensitive skin days. Also, possibly due to the vitamin ingredients, a yellowish color was left on the cotton pad when cleansing the next morning. While there was no lingering serum feeling, it's a good idea to cleanse thoroughly.
TipThis product is said to be most effective when applied immediately after cleansing, so it would be best to keep it in the bathroom and apply it right away. Also, if used together with the niacinamide product from the same line, you can see the effect of brighter skin in the morning, so if you want to focus on whitening care, it is also recommended to use them together!

I'm on my 6th purchase now and my skin has noticeably improved!!!
ConsI find the high concentration ones to be a bit too irritating, so I really like the 13 one!! If you have sensitive skin, use the 13.

I was initially not interested in functional cosmetics as I have sensitive skin, but I gradually became interested in skin brightening and wanted to try a vitamin serum. I happened to come across the COSRX Skin Booster & Vitamin Serum Set on sale at a good price, and since the reviews were positive, I decided to purchase it. When I read the reviews, many people mentioned seeing brightening effects and that it was non-irritating, so I tried it out. True to the reviews, there was no irritation, even though I was worried it might sting. The price was also very reasonable, so it was a great value. I think this product would be a good option for beginners.
ConsAs I decided to use the vitamin serum, the whitening effect is honestly the part I'm most looking forward to, but I'm not really sure about that. The concentration is low, and since it's written that I should be careful because of my sensitive skin, I don't know if that's the reason. Also, there was a slightly sticky and adherent finish. I bought it when it was hot and used it while refrigerating it, but it was a bit of a hassle. Unless I feel like the whitening part has improved in some way, I don't think I'll repurchase it.
TipWhen using a vitamin serum, use a soothing cream. When you should use a retinol cream, use a soothing serum. I learned not to use vitamin and retinol together, so I used them that way.

ConsAside from the slightly sticky feeling, everything else was great!

And I've never had any trouble because of this, and I really wanted my skin to become whiter and to get rid of skin discoloration, so I bought it and I'm using it with complete satisfaction.
ConsThe only downside is that the application method can be a bit inconvenient due to the nature of vitamin C. And there's a slight unpleasant vitamin C-like odor. Ah, and the short shelf life is a bit disappointing too - once it discolors, you have to discard the remaining product regardless of the amount.
TipIt seems that taking vitamin C supplements along with this product can have better effects on the skin!! It's also good to drink a lot of water at the same time!! You should apply this ampoule while your skin is slightly damp after toner application! And wait for 3-5 minutes before applying the cream, this will enhance the effects!! When using it during the day (daytime use is also great!), don't forget to use it together with sunscreen~~ Also, don't forget to store it in the refrigerator and use it!

It's definitely less stimulating than 23. I think those new to using it would do well to start with 13, and it's quite effective for skin pigmentation and whitening! It's better to say that the skin becomes brighter rather than whiter.
ConsIf you use it directly on bare skin, it can be irritating, so be sure to apply it as the second step after using a skin and toner.

Since it is pure vitamin C, it also has an antioxidant effect, of course. The color has a yellowish hue. When applied to poor skin conditions, it can cause more inflammation and chaos. I recommend using it when your skin condition is good.
ConsWhile it has a whitening effect, it can be irritating, so I recommend using only a very small amount if you have sensitive or reactive skin.
