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 only with a couple of months shelf-life.
The official shelf life of C-Glow is 6 months from production, unopened and stored in the fridge. To ensure maximum freshness, we manufacture small batches of C-Glow every week, and we store this product in the fridge in all of our warehouses. On average, by the time a C-Glow reaches our customers it is about 2-3 weeks “old”. We recommend you to store it in the fridge, too, where it keeps fresh at least for 3 months (if unopened, it keeps for a couple of months more), while it keeps about 6 weeks at room temperature. 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 5-10 days 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).
Ingredients & Research
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.
Dimethyl Isosorbide – A new-generation solvent that aids the proper penetration of Vitamin C + solubilizes the high amount of Ferulic Acid into the formula.

Love it. Absolutely love it. It's sublte, but I do notice a visible sort of shine or glow radiating from my skin after a few days of use.
I also have sensitive skin but this somehow doesn't affect me at all.
I've used a different one before, did not notice a thing. This one is amazing.
The best vitamin c I have ever tried!!! ❤️
High concentration ascorbic acid without any adverse side effects, such as redness or irritation (and I should know, being rosacea prone) made fresh every week, no discernible smell and it can be paired with other actives - I use it in combination with azelaic acid. I’m in my third batch and definitely plan to repurchase.
Le sérum c glow est tres agreable a utiliser, il est frais du fait de sa conservation au frigo et réellement efficace. Je recommande le sérum c glow.
J ai découvert Geek and Gorgeous grâce à Cyrille Laurent.
Le rapport qualité prix est excellent.
Je suis très satisfaite de cette vitamine C que ma peau supporte merveilleusement bien.
Seule petite contrainte, la ranger au réfrigérateur pour conserver toutes ses qualités.
