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).

I am very satisfied!
J'aime énormément ce sérum que je recommande régulièrement car il donne un super teint et un très bel éclat. J'apprécie également la fraîcheur du produit fabriqué régulièrement en fonction des commandes.
The best Vitamin C serum I've ever used (and I've used a lot). Nice texture, no smell, very reasonable price and excellent results. My brown spots disappeared and my complexion is clear and luminous after use of one month. I am on my fourth bottle and I'll continue using it in order to keep my skin in good condition. P.S. Worth mentioning, the excellent customer service of Geek & Gorgeous.
