The disadvantage of pure Vitamin C is that it is super unstable, and hard to formulate with. This formula uses a low pH and extra antioxidants to help to stabilize Vitamin C, but even like this, C-Glow comes with a relatively short, 6 months shelf-life.
The official shelf life of C-Glow is 6 months from production, unopened. To ensure maximum freshness, we manufacture small batches of C-Glow every week. On average, by the time a C-Glow reaches our customers it is about 2-4 weeks “old”. To minimize oxidation & maximize freshness, we recommend to store it in the fridge, where it keeps fresh even beyond its official 6 months shelf life. If going to the fridge every day for your C-Glow does not sound comfortable, we recommend to use this 10 ml mini bottle. You can easily decant a few weeks worth of C-Glow into it, and store the mini bottle in the bathroom, while having the C-Glow bottle in the fridge. Click here for the C-Glow mini bottle.
Who is it for?
how to use it?
Apply a few drops to the face after cleansing, before using other serums and/or creams. Ideal to use in the AM, but can be applied in the PM as well. As the C-Glow formula is water-like, we recommend that you put a drop directly onto your face and quickly pat it on with your other hand.
Shelf life: 6 months from production (unopened), 3 months PAO (period after opening).

Vitamin C (ascorbic acid – 15%) – A clinically proven active that gives the skin environmental protection (antioxidant), boosts collagen production and fades hyperpigmentation. Also gives an instant glow to the skin.
Ferulic acid + Vitamin E – Antioxidants that help to stabilize Vitamin C and increase its antioxidant power. The formula contains a high amount of Ferulic Acid, and a smaller amount of vitamin E.

The product itself works well, doesn't feel greasy on my skin. I shave my face every other day, and when I use it then it does burn. On my other days, when I use it in the morning it only stings a little sometimes. As for the results, I do feel like it helps with the pigmentation of my acne scars, so that's good. The product was shipped to Germany via gls, who I had some problems with, but that doesn't have anything to do with the product.
Generally I would recommend the c glow serum, as it's a lot cheaper than similar products, seems to be working well and is fairly accessible here in Europe. Just be aware that it might burn on freshly shaved or more sensitive skin.
I've been using it for a month and I can say it's an excellent serum. It absorbs quickly and my skin is softer and brighter.
Works well and a great price compared to other brands with the same-type product.
I got the mini bottle as suggested to keep in my bathroom but the dropper is a little too short to reach the product. I have to turn it sideways to be able to get some out.
I am thrilled! C-Glow has to be the best Vit C serum I’ve ever tried - and I’ve tried a LOT. At less than half the price C-Glow rivals the famed skinceuticals product that most cannot afford. You’ll see results after a month and now that I’m on month 3, I will be a regular. No sticky after feel, no chemically scent. Per instructions, it does need to be stored in a cool dark place, however mine didn’t turn after a month. In the summer months I’ll be more careful & decant my weekly supply into a spare bottle (my fridge in on a separate floor from my bedroom.)
Unbeatable price. I definitely recommend this serum and will continue to repurchase it.
I keep it in the fridge, as recommended.
