- as*******Combination SkinAcne SkinSebum/BlackheadsDark CirclesRecommendedApr 26, 2025
I've been using this for about 6 months now, and while I'm not sure about the brightening effects, I can definitely feel an improvement in my skin texture. To be honest, I'm not sure about the brightening effects. You need to use more product per application than expected. - ch******Normal SkinAcne SkinBrightening/Dark SpotsWrinkles/ElasticityRecommendedApr 3, 2025
Among affordable niacinamide serums, this is my top recommendation. It contains 10% niacinamide + 10% vitamin C derivative & panthenol, plus other great ingredients! I'm extremely satisfied with this product. There's nothing I can really complain about. They've even improved the packaging, which is a nice bonus. - ro****Oily SkinAcne SkinRecommendedApr 1, 2025
The price is incredibly reasonable considering its performance and volume. It's an excellent niacinamide ampoule. I've finished one bottle and repurchased. While I'm not sure about its whitening effects, it definitely improves skin texture and brightens the complexion. This product has made me remember the brand ISOI, and I occasionally buy their new releases. The container is also great - it's like a dropper, making it easy to control the amount. It's not unnecessarily large, fits perfectly in one hand, making it very convenient to use. There's nothing I found disappointing. But since I need to write 20 characters: I'm satisfied with its performance, price, volume, and packaging. However, as it contains a high concentration of niacinamide, I recommend those with super sensitive skin to opt for a milder product. If you do purchase it, start with just one or two drops. - me****Oily SkinAcne SkinRecommendedMar 27, 2025
It absorbs as smoothly as water. Great even for combination dehydrated skin! While the packaging is slightly disappointing, everything else is quite satisfactory. - yy******Combination SkinSensitive SkinSebum/BlackheadsDark CirclesEnlarged PoresRednessRecommendedMar 27, 2025
I'm really satisfied because I feel like my complexion definitely brightens up with consistent use There wasn't anything particularly disappointing! I just hope the Isoi brand continues to operate - du********Combination SkinSensitive SkinAcne SkinInner DrynessRecommendedDec 20, 2024
The brightening effect is definitely noticeable, though I'm not sure about the vitamin C The volume is a bit small. While the 10% version comes in 100ml, this one is only 50ml... - 87*****Combination SkinSensitive SkinAcne SkinAtopic SkinRecommendedOct 21, 2024
The price is incredibly reasonable. It's a cost-effective ampoule containing niacinamide. While the brightening effects might need consistent use to be noticeable, it seems to have a slight impact on blemishes and helps refine skin texture, making makeup application smoother. However, given the active ingredients, it's great if it suits your skin, but for those who might be sensitive to niacinamide, I recommend starting with a small amount and gradually increasing usage. Nothing in particular! An ampoule priced just over 10,000 won is such a bargain. I hope they maintain this price without any increases. - qn******Oily SkinAcne SkinSebum/BlackheadsDark CirclesWrinkles/ElasticityEnlarged PoresRecommendedOct 9, 2024
30s / Male / Oily skin / Prone to excess sebum and acne Before using this product, I used to apply vitamin C and niacinamide serums separately. I decided to purchase this product because it combines both ingredients, and I thought the vitamin derivatives might be less irritating. - Absorption: It has a light, water-like texture similar to a toner. It applies smoothly and absorbs well into the skin! The squeeze bottle is more convenient than a dropper. - Effectiveness: After using up one bottle, I can say it's gentle and non-irritating. While the effects might seem less noticeable compared to my previous products, I think it could be better in the long run. It seems to focus more on skin soothing, which isn't bad at all! One of the biggest advantages is its affordable price, making it accessible. The ingredients are also trustworthy. Since I used to apply two separate high-concentration products before, I feel like the brightening effect is less noticeable with this one. For best results, I recommend applying sunscreen after using this product or incorporating it into your night care routine. It's also said to be more effective if you apply this product right after your toner, let it absorb, and then continue with the rest of your skincare routine. - js********Oily SkinSensitive SkinAcne SkinRecommendedSep 27, 2024
It's hard to find a product this good at this price point. I wholeheartedly recommend it! It seems they've changed it to a dropper format now, but mine wasn't like that. I didn't like how it turned yellowish and stuck together. - ki********Dehydrated SkinSensitive SkinSebum/BlackheadsInner DrynessWrinkles/ElasticityEnlarged PoresRecommendedSep 7, 2024
While not dramatically transformative, this niacinamide essence is wonderfully gentle and hydrating, making it perfect as the first step in your skincare routine I can't think of any downsides... Personally, I find the packaging very convenient to use. Despite the large volume, the compact size makes it even more appealing
