This is my first time trying the hyaluronic acid serum from Isoi, and wow - my skin is absolutely glowing! The hydration level is just perfect. If you're a fan of that radiant look, apply it the night before and you'll have a beautiful canvas for your makeup the next day. With its affordable price and generous amount, there's really nothing to complain about. I'll definitely keep using this product. The serum provides that coveted "Inner Glow" effect, leaving your complexion looking luminous and healthy. It absorbs well without feeling sticky, making it ideal for layering in your skincare routine. This product works hard to even out your skin tone and boost hydration, which is great for those with combination dehydrated skin or anyone looking to achieve that lit-from-within radiance. - ko******Dry SkinSensitive SkinRecommendedJun 26, 2025
This serum has a slightly brownish, runny texture reminiscent of nasal mucus. Thanks to its hyaluronic acid content, it feels wonderfully hydrating when applied. The formula isn't overly sticky, making it comfortable to use. It applies smoothly even with multiple layers, making it convenient to use. - dm********Combination SkinSensitive SkinRecommendedJun 22, 2025
Thanks to the hyaluronic acid, I was able to use this product with great hydration. Even though I have combination dehydrated skin and layered it a few times, I didn't experience any blemishes. The product's opening is not ideal. I think a dropper would have been more convenient. - th*******Dehydrated SkinSebum/BlackheadsDead Skin CellsRecommendedJun 11, 2025
It's so hydrating and lovely! The packaging is designed for easy squeezing, making it super convenient to use. The scent is really not my cup of tea... Personally, if it weren't for that, it would be absolutely fantastic. This product offers great hydration and user-friendly packaging. However, the fragrance might be a dealbreaker for some. If you're not sensitive to scents, you'll likely find this to be an excellent choice. - py******Oily SkinAcne SkinAtopic SkinRecommendedJun 2, 2025
Skin type and focus areas: Combination dehydrated skin with concerns about pores, excess sebum, and redness Packaging: This was my first time using this type of container, but it's incredibly user-friendly. I wish all products came in this packaging! The generous volume offers great value for money, especially for someone like me who loves to apply skincare products liberally. Texture: It doesn't drip when applied directly to the face. The consistency isn't sticky or heavy, but has a pleasant lightweight feel with just the right amount of substance. Application experience: It provides ample hydration without being excessive, and the moisturizing effect lasts for a long time. As someone who doesn't wear makeup but uses mineral sunscreen, I'm pleased to report there's no pilling. It also layers well with most other skincare products. Scent: Seems to be fragrance-free? Comparison with other ampoules and serums I've tried: I'm truly satisfied. The ease of use, volume, absorption, and long-lasting hydration are all excellent. I'm definitely considering repurchasing. I haven't experienced any disappointments while using this product. There were no blemishes, and the product is genuinely good. - li*****Dehydrated SkinSensitive SkinAcne SkinSebum/BlackheadsDark CirclesEnlarged PoresRecommendedMay 28, 2025
It was a decent product. I appreciated being able to try it out at such an affordable price. I can't say there was anything particularly disappointing about it. - ra******Combination SkinBrightening/Dark SpotsSebum/BlackheadsInner DrynessEnlarged PoresDead Skin CellsRecommendedApr 28, 2025
I've been using this for a month after receiving it as a gift from a friend, and I even gifted it to my parents. It's been gentle on the skin, and I've noticed that using just a small amount has kept my skin hydrated. My wrinkles have reduced, and my complexion has visibly brightened. I've learned that consistent application is key. So far, I haven't found any drawbacks. However, for those used to applying generous amounts of product, it might be disappointing that only a small amount is needed. I recommend applying a small amount separately to the neck and face. - rl*******Dehydrated SkinSebum/BlackheadsInner DrynessEnlarged PoresRednessRecommendedApr 27, 2025
As someone with combination dehydrated skin, I'm always on the lookout for hydrating products, and when it comes to hyaluronic acid, you can't go wrong! I really enjoyed using this because of its clear formula that absorbs well into the skin. I have to say, the scent wasn't particularly pleasant. But I suppose that might mean it contains fewer artificial ingredients? - ho*******Dehydrated SkinSensitive SkinAcne SkinAtopic SkinBrightening/Dark SpotsSebum/BlackheadsDark CirclesInner DrynessWrinkles/ElasticityEnlarged PoresRednessDead Skin CellsRecommendedApr 26, 2025
I've been using this product so diligently that the outer packaging isn't even pristine anymore. It's a serum that feels like an ampoule, so I find it to be great value for money. The ingredients are excellent, which is why it works so well for me. I love that I can skip toner, apply this product, and follow up with a hydrating moisturizer for non-sticky, deep hydration. The scent is a bit peculiar - slightly reminiscent of traditional herbal medicine. Those who don't appreciate that kind of fragrance might find it off-putting. - kt*****Oily SkinSensitive SkinAcne SkinRecommendedApr 20, 2025
I've been using this for 5 years now. While it's fragrance-free, it absorbs well and provides excellent hydration. There's nothing I can really fault it for so far. It seems to be the most reliable option.
