Review: One of the Best Vitamin C Serums I’ve Tried - 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.
Review: UTTERLY AWESOME FORMULATION - Super Potent & Non-Irritating - Excellent Price Point! - 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!!
