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).

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.

My absolute favourite vitC serum. Affordable and effective. When stored in the fridge, no oxidation for months.... So recommend using mini bottle to decant.
C-glow is one of the best (and most affordable) L-ascorbic acid serum I've ever used. It helps to brightens the skin and even out the skin tone and just gives a gorgeous glow to the skin.
I really like this serum so far. I‘ve been using it for about a month now and can already see my dark spots from picking on my skin (shame on me) fading! The texture is quite runny, so be careful when dropping it onto your hand!
Endlich ein Vitamin C Serum, das meine Haut nicht irritiert, sondern toll befeuchtet, und sie mit schönem Glow beschert. Nie mehr ohne!
I love your Vitamin C, and would love to order it every 3 months, but in order pay a reasonable shipping costs of 5 eur, i have to spend at least 25 euros. I don't need so much skincare every 3 months. If I buy only couple of serums, it is still not 25 eur and i have to pay 15 eur for shipping. It is unreasonable to have such high shipping costs and I have not seen any brand asking to spend 25 eur at their shop to het a decent shipping costs for 5 eur. Yes, if someone spends 50 eur , you can grant a free shipping, but others maybe want to buy a few serums plus a reasonable shipping costs, but that is not possible in your store. It is a pitty, because i do love couple of products of G&G but I cant afford these shipping costs.:( I hope you can consider to make them more reasonable.
