I always thought Vitamin C serums were harsh, but COSRX's Pure Vitamin C 23 Serum surprised me with its gentle and smooth application. The texture is like a thin oil that flows like water, but once applied, it absorbs quickly with almost no stickiness. At first, I thought, "Isn't this too oily?" due to the oil layer, but after absorption, my skin felt firmer with a noticeable glow. I prefer lightweight basics with definite results, so I discovered this product while looking for a high-concentration Vitamin C. With 23% pure Vitamin C, it visibly brightened my dull complexion. I'm especially pleased to see a gradual fading of my recent sun spots and blemish marks. Recommended skin type? It worked particularly well for my sensitive, combination skin prone to blemishes. For those with sensitive skin, I suggest using it every other day at first to allow for an adjustment period. Thanks to its soothing ingredients, I didn't experience any tingling or redness. What I appreciated most was the inclusion of hydrating and calming ingredients like hyaluronic acid, allantoin, and niacinamide. This meant I could use a high-concentration vitamin serum without disrupting my skin's balance. And the ingredients are truly impressive... It contains Vitamin E (tocotrienol) to prevent oxidation, plus glutathione, caffeine, and squalane... It feels like a complete skin care serum!
ConsLike most Vitamin C serums, storage can be a bit inconvenient. It needs refrigeration and should be used within two months of opening, which might be challenging if you tend to stockpile skincare products. There's also that distinctive vitamin scent... While you get used to it, at first you might think, "Is that a hot dog smell?" Although I experienced minimal irritation, depending on your skin type and condition, you might feel a slight burning sensation at first. For those with sensitive skin, I strongly recommend doing a patch test!
TipAfter cleansing and toning, I pat the Vitamin C serum into my skin and wait about 2 minutes. Then I finish with a moisturizer, and my skin feels incredibly firm! If you want to use it in the morning, sunscreen is an absolute must! While it gives you a glow, sun exposure can actually be counterproductive, so I strongly recommend pairing it with a physical sunscreen of at least SPF 50. Keeping it cool is a real treat. Storing it in the fridge not only cools your skin when you apply it in the morning but also leaves you feeling refreshed - it's a win-win!

After using it for 3 weeks, while I haven't noticed my dark spots fading, I can definitely feel that my complexion has brightened.
ConsI'm not sure if it's a design flaw or if I'm just not closing it properly, but the lid doesn't seal correctly and keeps spinning loosely. Even when I try to tighten it, it won't stay closed, so I'm trying to use up the product as quickly as possible...
TipI heard that vitamin serums are sensitive to temperature, so I've been keeping it in the fridge during summer. It feels refreshingly cool and nice to use!

The review is completely unbiased and honest, with no guidelines or restrictions. 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.ProsI've been using this for about 3 weeks, and I love how lightly it applies. Many high-concentration vitamin products tend to be sticky, but this one goes on very smoothly with less irritation (though not completely irritation-free). It does feel a bit rich, but it's not overly sticky and leaves a soft, velvety finish. I've never experienced any tingling when applying it, and it hasn't caused any blemishes, making it great for daily use.
ConsFirst off, the color is somewhat yellowish, and the texture is quite unique. When you drop it on your skin, it doesn't adhere at all - it rolls around like oil. Even when you try to rub it in, it feels as if your skin has become water-repellent, with droplets forming instead of absorbing immediately (maybe because my skin is dry?). It feels more rich than hydrating. I noticed something peculiar while using it... After applying this serum, if I try to layer on a soothing gel or hydrating ampoule, those products turn watery and just drip off like when you're washing your face. I was so shocked at first! I tried to use an aloe gel pack, but it just turned into liquid and started dripping. The same thing happens with sheet masks, though not as severely. They say vitamin products should be applied in the first step, but with this one, I think it might be better to apply it later in your routine. I hope this information is helpful for those using this product.
TipSince this product turns other hydrating products into water when layered, it might be better to apply it in a later step when using multiple ampoules, or make sure it's fully absorbed before applying other products.

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.ProsI bought this product hoping for its effects on dark spots and skin brightening. It applies smoothly like a toner and absorbs quickly into the skin. Although it has a water-like consistency, after it dries, it leaves a slight yellow tint, making it easy to see where you've applied it. When purchased on sale, I think it's a cost-effective vitamin ampoule.
ConsThe bottle is opaque and uses a dropper, which makes it a bit difficult to check how much product is left. I feel a slight irritation when using it.
TipThis product seems to work hard on improving complexion and evening skin tone. It absorbs well without feeling sticky, which is great for those with combination dehydrated skin. The slight yellow tint it leaves behind could contribute to that coveted "Inner Glow" effect. However, those with super sensitive skin should be cautious due to the potential for irritation. It might be a good addition to a daily skincare routine for those looking to boost their hydration and brighten their complexion.

The absorption is excellent.
ConsThere's nothing disappointing to report yet. It's a set of two, and I appreciate that it comes with a separate dropper, which makes it more hygienic.

However, if you have dry skin, you might want to finish with a more moisturizing cream or add a hydrating essence before this step!
ConsI didn't know there was a 16 shade and started with 23. At first, it felt quite tingling and seemed to irritate my skin. So I tried applying it after a hydrating essence, which reduced the tingling sensation!

The absorption and application are quite nice too. Even with the characteristic fishy scent of Vitamin C, it's still worth using when you take that into account.
ConsThe scent is a bit... noticeable. While all Vitamin C serums tend to have this issue, this one seems a bit stronger, probably due to its higher concentration.
TipBe cautious when applying to areas with blemishes or wounds, as it may cause a tingling sensation. If you have super sensitive skin, it's best to do a patch test first. This product contains pure Vitamin C rather than a derivative, so it might cause irritation or breakouts for some people.

It's not overly sticky and absorbs well into the skin. Rather than providing dramatic results, it gradually brightens the complexion over time.
ConsThe product volume is quite small, resulting in a short usage period. It's also challenging to layer with other skincare products.

ConsI used it diligently every evening for a month, but didn't see any results. I'm not sure if I need to use a few more bottles, but with one bottle I didn't notice any difference in brightening or other effects...
