Gluta Vitamin C Brightening Serum | 25% Pure Vitamin-C and 1,000ppm Glutathione, Anti-Aging and Anti-Oxidant, Reduces Dark Spots, Korean Skincare, 0.78oz.

I’ve been using this IOPE Gluta Vitamin C Brightening Serum for about three weeks, and it’s honestly excellent. I’ve tried a lot of Korean vitamin C serums over the years, but this one really stands out. My skin looks noticeably brighter and smoother, and I’ve had zero irritation — which is saying something for a 25% vitamin C formula. It feels strong but balanced, and the added glutathione really helps keep my skin calm and even. I’m 52 and post-menopausal, so my skin can be a little reactive, but this gives me a healthy glow without drying me out. It’s definitely more expensive than some others, but worth it for the results. Just remember: this is a fresh formula — you’ll want to store it in the fridge or use it within about a month to keep it potent. IOPE did an amazing job with this one. It’s potent, effective, and feels like something you’d get from a dermatologist’s office rather than a regular serum.

I'm not sure everyone appreciates just how much research and innovation goes into every bottle of IOPE skincare, and this Vitamin C serum is an excellent example of that. This is a very high percentage of C and IOPE has managed to formulate it in a way that it is non-irritating and super powerful - it's absolutely the best C I have used and it comes in at an excellent price point. Keep in mind that this is designed to be used fairly quickly - the bottle symbol states that this should be used in 2 months from opening so don't waste it by letting it sit around turning color (like we all do with our vitamin C serums). I saw results by the end of the first week and will be buying this again once I finish this bottle, although I think a new formulation is coming soon! Pair this with any of the IOPE STEM III moisturizers and you will have a perfect daily skin routine, and keep it in the fridge both to keep it potent and slow the color change as well as to have it be a little blast of cold on your skin in the morning. Love it!!

My best of them all Just one week of use I saw massive changes

I saw results on my face and neck after a week. My skin looked more radiant and illuminated. It also toned my skin. I am very happy with this product. I use it every night, dries quickly and a bottle last me about a month and 2 weeks. I follow it with a night moisturizer because your skin will feel tight and it was hard for me to go to sleep with that tight feeling.

No visible change after 3mo of consistent use. Not sure if the product was no longer effective when arrived as it released a lot of air as I opened the bigotte as if it was fermented. Texture: sticky.

Moisturizing, smooth application, fast absorption and good texture. I just can't seem to get over the weird, "gassy" smell it has. It must be the Glutathione because Vit C normally doesn't have that scent.

The vitamin c comes in an amber glass bottle sealed tight and the dropper is packaged separately in the box. As warned on the packaging, when you open the bottle, there is a release of gas. The serum does not smell the best, but I’ve experienced worse. So far it's been good, I haven't experienced any allergic reaction to the serum. It is a little sticky, but dries fairly quickly.

Love it it forms and brightens the skin not sticky once dry doesn’t leave skin oily.

なんかいい

1本使い切いきりました！ 使う前とお肌が全然違う!!! まず、透明感爆上がりしました!!! お肌もパーンとはって毛穴も目立たなくなり、全体的に弾力upしているのが分かりましあ！ これまで色んなアンプル使って来ましたが、ここまで効果があるのは初めてです。

肌がなんとなくスッキリしないのでトーンアップ 用に使ってみました 肌がふっくらするようで気になっていた毛穴部分が 目立たなくなってきたようです

ピュアビタミンC25は結構濃厚だと思います。 そのせいか独特の香りがしますがそんなに耐えられないということはありません。 塗った瞬間から肌に吸い込まれるような感じで、 少し経つとピタピタという手触りに変わります。 角質の改善とトーンアップに期待します。

楽しみに箱をあけたら、、、、。 こんな事に、返品手続きします。
