I bought a product with a high content without knowing much, but fortunately I didn't feel any irritation. There may have been a sense of irritation when the skin barrier was compromised. It seems to work well with hyaluronic acid toners or ampoules. I recommend applying them together.
ConsThe ingredients are good and the cost-effectiveness is great! There are no troubles and there is absolutely nothing to be disappointed about.
TipPlease refrigerate. They also said that using it with a galvanic device increases absorption.

However, I had a previous experience of using a highly concentrated product that stung, so I couldn't use it properly. This time, I decided to purchase the Cosrx Vitamin C 23 Serum as I was looking for something gentle yet effective. The vitamin C concentration is quite high at 23%, but surprisingly, it's not overly irritating. The texture is a lightweight, slightly oily feel. It's not completely watery, but has a slight viscosity, which makes it easy to spread on the face and absorb well, leaving the skin looking slightly dewy and smooth. There was a slight tingling sensation when I first applied it, but that went away quickly. On sensitive days, it may still feel a bit stinging, so I skip it on those occasions. I've noticed improvements in my skin tone. With consistent use, my face looks brighter and more radiant. It has also helped fade some dark spots and acne scars, though they don't completely disappear, and the effects are gradual with continued use.
ConsThe point is that it is difficult to store! Due to the characteristics of vitamin C products, they are easily oxidized, so they must be refrigerated and the lid must be tightly closed after use. And although there was hardly any yellow tint when I first opened it, I noticed that it gradually became darker over the course of a month or two, so oxidation is definitely progressing. So it seems important to use it up quickly.
Tipit's great if you stock up during sales ㅎㅎ

Reviews by The Hwahae Testers undergo the same strict verification process as regular reviews, and if they don't meet our standards, revisions will be requested.ProsSkin type: combination/dry, late 20s😭 ✔ High vitamin C content with minimal irritation Despite the high 23% vitamin C concentration, there was little to no stinging or redness, unlike some other vitamin C products. Even with my sensitive skin, it absorbed comfortably after use☺️ ✔ Brightening effect on skin tone After about a week of use, my skin felt brighter overall. Existing minor blemishes seemed to fade, and when I applied it on dull-looking skin, it noticeably brightened my complexion. ✔ Fast absorption and lightweight feel It has a hydrating texture without any oily residue, absorbing quickly without stickiness! It seems like a good match for those who dislike the heavy feel typical of vitamin C serums.
ConsThe dropper format makes it convenient to control the amount, but the serum has a viscous texture, so it gets a bit sticky as it gets on the hands or the bottle opening.
TipStart with a small amount to help your skin adapt. Apply in the order of toner → vitamin C serum → moisturizing cream. After refrigerating, gently warm it in the palm of your hand before applying. Focus on using it in the evening, and use sunscreen during the day. Apply an extra layer on blemish marks. Using it after exfoliating will increase absorption. Following these steps will allow you to use the products more effectively without irritation.

However, even though it's a high concentration, there was no irritation at all. The best part was that there was no irritation. While the serum doesn't provide exceptional hydration, it applies and absorbs well. I haven't used it long-term yet, but I'm hoping to see improvements in dark spots and brightening effects.
ConsThe disappointing aspect seems to be nonexistent. The price is also reasonable when purchased during sales.
TipAccording to the dermatologist on YouTube, it's best to use it in the initial basic step, allow sufficient absorption time, and be sure to apply sunscreen in the morning when using it.

I have repurchased it multiple times, and while I haven't seen a dramatic effect, it seems to help maintain my skin's elasticity.
ConsThe overall skin tone seems to have brightened, but I haven't seen any effects on freckles.
TipThis product contains resveratrol+ferulic acid, or vitamin E products can be additionally applied to enhance the efficacy of vitamin C, so I have been applying them that way.
