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.
Dimethyl Isosorbide – A new-generation solvent that aids the proper penetration of Vitamin C + solubilizes the high amount of Ferulic Acid into the formula.

Best formulation for a pure form of vitamin C.
My skin loves it! It’s the first step of my morning skincare routine after cleansing. No irritation, spreads beautifully over my dry and mature skin.
Results: healthy skin, well protected against sun and pollution damage. Even completion.
Together with other serum, helps fade my dark spots.
Ne me donne pas d'irritations.
ça fait des années que j'utilise C-GLOW.
En plus avec un excellent rapport qualité prix.
Très satisfaite de ce produit.
Great value Vitamin C that really works. Applies smoothly, does not leave sticky feeling on skin, interacts well with other skin care products.
I see an improvement in my skin tone, it is more radiant, dark spots are definintely lighter, although I've been using this serum only few weeks in my morning routine. Used another much more expensive serum before and have not noticed such an improvement as using G&G!
Will definitely repurchase.
For someone it is not very convenient to keep it in fridge, for me it is fine.
This is a very light serum that effectively rejuvenates your skin with out breaking it out!
