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.
To ensure maximum freshness, we create C-Glow in small batches once a week (on average, by the time a C-Glow reaches our customers it is about 2-3 weeks old, and we store C-Glow in the fridge in all of our warehouses). We also recommend you to store it in the fridge, where it keeps fresh at least for 3 months (if unopened it keeps for a couple of month 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 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: 4 months from production (unopened), 3 months PAO (period after opening) - but as C-Glow is on the market now for more than 2 years, we can say from experience that stored in the fridge unopened it keeps fresh for 5-6 months.
