dk********Dehydrated SkinSensitive SkinAcneInner DrynessWrinkles/ElasticityEnlarged PoresRednessRecommendedMay 14, 2026 (UTC+0)I did my research before buying this product, and I'm using it every other day. I can honestly say it's delivering results! The day after I apply it, my skin looks noticeably brighter and more radiant. It does feel a bit rich, but it absorbs well without any issues. Nothing really to complain about. Apply right after cleansing, before toner, for best absorption. 
pk***Combination SkinSensitive SkinAcneInner DrynessEnlarged PoresRecommendedApr 29, 2026 (UTC+0)One reason I don't use vitamin C serums regularly is because of how they feel on the skin, but this one doesn't have that typical slippery sensation. It doesn't sit on top of your skin leaving behind that oily residue—instead, it absorbs beautifully and feels like it's melting right in. After using it consistently for about two weeks, I noticed my skin texture became smoother and my complexion looked noticeably brighter. That said, I was being really intentional about my skincare routine during that time, so other factors probably played a role too. But honestly, the texture was so pleasant that it didn't matter—I was happy with it. The results weren't as dramatic as I'd hoped. Beyond the texture, I couldn't really pinpoint what makes this stand out compared to other brands—nothing that would make me think, "I definitely want to repurchase this over everything else." - ke*******Combination SkinSensitive SkinAcneBrightening/Dark SpotsSebum/BlackheadsDark CirclesRednessDead Skin CellsRecommendedFeb 28, 2026 (UTC+0)
This formula has such a lightweight, water-like texture! It absorbs beautifully and leaves your skin feeling plump and bouncy. I'm really excited to see how it tackles blemishes and brightens my complexion over time. The feel is great, and considering the high concentration of active ingredients at this price point, I'm giving it a full five stars. I'll come back with an update after a month of using it. Since this contains 23% ascorbic acid, I did experience some tingling when I first applied it. The bottle felt like it wasn't completely full, which was a bit disappointing. When it arrived, it felt so light that I honestly wondered if they'd sent me an empty container! I read reviews mentioning that this oxidizes faster than other similar products, so I've been storing mine in the refrigerator to keep it stable. - rn*********Dry SkinSensitive SkinAcneAtopic SkinRecommendedFeb 22, 2026 (UTC+0)
1. Great Value for Money This vitamin C serum oxidizes quickly, so it's recommended to use it within three months. That's why it comes in a small 20ml size. Even considering this, it's more affordable than competing products—I picked mine up for under 10,000 won. 2. Smart Packaging Design The dark, opaque bottle protects against light-induced oxidation so you can't see the contents. To prevent oxygen-related breakdown, the bottle comes sealed with a protective seal the first time you open it. 3. Excellent Oxidation Stability Even after two months of use with refrigeration, there's barely any color change. 4. Minimal Irritation There's a slight tingling, but it doesn't cause breakouts or any adverse reactions. 5. Impressive Results on Discoloration and Scars Doesn't do much for age spots or freckles, but it works incredibly well on post-acne marks. (I lost my before photos, so I can't share a comparison.) It outperforms pharmacy scar gels like Scar Derm. Compared to using scar cream for a month, then stopping for months, then using this vitamin C serum consistently for a month and a half—this serum caused less irritation, wasn't as itchy, and delivered better results. 6. Noticeably Improved Skin Barrier The high-concentration vitamin C boosts collagen production, so my dull, rough skin definitely feels more hydrated and healthier overall. That said, fine lines—especially smile lines—didn't see major improvement. You'd probably need longer-term use or professional treatments for those. 1. Can Cause Tingling Around Eyes If it gets in your eyes, it stings quite a bit. Be extra careful, especially if you wear contacts regularly or have had vision correction surgery. 2. Leaves Yellow Stains on Surrounding Items If you apply it before bed, I'd recommend using disposable pillowcases. Even small amounts on your hands leave stubborn yellow marks, so wash your hands thoroughly after use. 3. Oxidation Prevention Requires Care Once oxidized, it can actually harm your skin, so always seal the bottle tightly and store it in the refrigerator after each use. 4. Dropper Doesn't Reach the Bottom When there's a little left sloshing around at the end, you have to pour some into a small dish, tilt it, and use the dropper to suck it up before dotting it on your face. It's tedious. (I don't recommend just rubbing the sticky residue on your hands since it leaves yellow stains.) 5. Skip the Powder Since ascorbic acid is water-loving and absorbs better when slightly tacky, leave your skin feeling dewy rather than powdered. If you use powder, it'll pill and flake off like dirt (speaking from experience). 1. Prep with a Mild Acidic Toner Dampen your face with a pH-balanced toner first so the water-loving, acidic ascorbic acid absorbs into your skin more effectively. 2. Wait About 15 Minutes Give the serum time to fully absorb after application. 3. Layer with Hyaluronic Acid Serum Apply one or two drops of hyaluronic acid serum next. 4. Wait 5 More Minutes 5. Apply a Barrier Cream Lock everything in with a nourishing moisturizer. 6. Finish with Sunscreen Use your go-to SPF product to complete your routine. - sy*****Dehydrated SkinAcneBrightening/Dark SpotsInner DrynessWrinkles/ElasticityEnlarged PoresRednessRecommendedJan 13, 2026 (UTC+0)
I've been using vitamin C consistently because of dark spots and uneven pigmentation, and honestly, it's become my holy grail product now. I really recommend sticking with it regularly. The absorbs beautifully, and after using it, my skin texture feels noticeably smoother and more refined. The price point is a bit disappointing. The dropper feels stuck, which makes it frustrating to use every last drop. Make sure to store it in the refrigerator and use it in the morning—sunscreen is absolutely essential after applying this product. - yj****Combination SkinSebum/BlackheadsEnlarged PoresRecommendedJan 3, 2026 (UTC+0)
This is my third repurchase! My complexion has become so much clearer, and those stubborn spots and blemishes have really faded. I'm keeping this as a lifetime staple in my routine. I'm absolutely thrilled with it. The formula is a bit too thin and tends to run, which is disappointing. That said, considering the price and how well it actually works, it's honestly not a dealbreaker. I'm really loving this product. No additional context needed for translation. - yj****Combination SkinSebum/BlackheadsEnlarged PoresRecommendedDec 13, 2025 (UTC+0)
This is my second repurchase! After trying the first bottle, I noticed my dark spots and acne marks started to fade, which made me so happy. I decided to buy it again because I'm really seeing results. I'm planning to keep using it consistently. The texture is quite thin, so I'd recommend dispensing it into your hand first before applying it to your face for the best results. The synonym list provided includes relevant terms like "blemishes" (여드름), "complexion" (피부톤), and "hydration" (수분) that could enhance cosmetics-related descriptions. The translation maintains a friendly, consumer-oriented tone while removing any cultural idioms and ensuring natural expression of satisfaction and product experience. - rn*********Dry SkinSensitive SkinAcneAtopic SkinRecommendedDec 10, 2025 (UTC+0)
*This review was written on the day of first use. 1. Antioxidant packaging The packaging is really thoughtful, especially since this contains pure vitamin C. The dropper comes separately sealed to prevent unnecessary air exposure. 2. Irritation The irritation is actually milder than I expected. When I layered it 2-3 times, I only felt a slight tingling sensation that goes away if you wait it out. Personally, I found it less irritating than 7% glycolic acid. My skin is super sensitive with a history of eczema and dryness. I had recently damaged my skin barrier and spent a week recovering before trying this. The only issue was one small blemish that turned red, but otherwise no major side effects. 3. Ingredient formula With 23% ascorbic acid plus panthenol and vitamin E, the high-concentration vitamin C absorbs stably and the panthenol helps reduce some of the irritation. I really appreciate getting such potent vitamin C without excessive irritation and at a great price point. 4. Value for money I purchased it on sale for around 14,000 won, which is even cheaper than CosRX. I'm really happy with that price. 5. Oil and moisture balance When I layered it 3 times, it felt sticky and rich. There's a protective film sensation, so I didn't experience significant dryness afterward. Those with oily skin might find that sticky layer uncomfortable. I have some pretty noticeable acne scars on my cheeks, and I'll share results on whether this helps after a month! 1. Oxidation concern (will check again after a month) Depending on the lighting, it looked slightly yellowed from the first day I opened it, suggesting oxidation (see photo 1, taken against white paper). Other reviews mention the oxidation happens fairly quickly, so I'd recommend sealing the container tightly and treating refrigeration as essential, not optional. 2. Packaging improvement wish (individual sachets) I've seen affordable plastic containers with individual vitamin serum vials like artificial tears these days. If this vitamin C came in that format, it would prevent oxidation and be even better. 3. Pilling occurs After cleansing, I applied the vitamin C 2-3 times on bare skin, waited 10-15 minutes, then layered my usual products and mineral sunscreen. After 2-3 hours, it started pilling like dead skin cells (see photo 2). The skin looks smooth on the surface, but when I rub with my fingertip or nail after the sunscreen sets, white flakes come off like dead skin. This pilling doesn't happen without sunscreen. When I apply powder over the mineral sunscreen, by evening when I use cleansing oil, it completely wipes away like eraser shavings. *Products used - Wellage hyaluronic acid serum - Purito squalane toner - O'TwoLab Ectomide Derma cream or Aestura Atobarrier 365 cream or Illiyoon Ceramide intensive cream - Pure mineral sunscreen 4. Slight dryness after application When I move my face, my eye area and cheeks feel a bit tight and dry. This seems like a natural characteristic of vitamin C serums. Personally, I don't mind since it reduces the excess oil on my T-zone that usually bothers me, but I should be careful when going out. 1. Refrigerate the product 2. Layer multiple times on slightly damp skin after cleansing (this balances pH and creates a hydrophilic environment for better absorption) 3. Apply 2-3 layers 4. Wait about 10 minutes, then apply hyaluronic acid serum 5. Wait about 1-2 minutes, then apply moisturizer 6. If using during the day, sunscreen is absolutely essential (this is also mentioned in the product description) *I plan to use this every 2-3 days due to skin sensitivity (for example: Wednesday-Saturday or Monday-Wednesday-Saturday). I've heard that it takes about 30 minutes for products absorbed in the dead skin cell layer to penetrate deeper, so on weekends I might use a humidifier and take my time applying it while watching videos for a more relaxed routine. - ki****Dehydrated SkinSensitive SkinAcneBrightening/Dark SpotsSebum/BlackheadsDark CirclesInner DrynessWrinkles/ElasticityEnlarged PoresRednessDead Skin CellsRecommendedNov 20, 2025 (UTC+0)
This product is wonderfully straightforward and reliable. It doesn't cause any irritation, and it absorbs beautifully with a lightweight feel that makes application effortless. Be careful when you first open this! Compressed air bursts out and sprays the solution everywhere. The actual amount of product inside is disappointingly small compared to the bottle size. When you pick it up, it feels like there's barely a fifth of the bottle filled. The reviewer appreciated the gentle formula and smooth application, but felt misled by the packaging—the bottle appears much fuller than it actually is, with significant empty space inside. - yj****Combination SkinSebum/BlackheadsEnlarged PoresRecommendedNov 19, 2025 (UTC+0)
I'm really impressed with this high-concentration vitamin serum! A tiny bit accidentally got in my mouth while I was applying it to my face, and wow, it's seriously tangy. The price point is fantastic for such a potent formula, and I'm definitely planning to keep using it regularly. The texture is way too thin and runny—it just drips right down my face. I think I'll need to dispense it into my hand first before applying it. No additional context needed for these reviews.
