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).

This is the best Vitamin C I’ve tried that actually works and I’ve tried a lot! Plus it’s cheap. 😍
As a guy, skincare can be a world of something we’ve never experienced. I found G&G on a post and was stoked that their website explained everything that the products were used for as well as their ingredients. The C glow specifically makes my skin feel refreshed and renewed. I’ve been using it in the morning and night for about a month and I feel like it’s making a huge difference in the appearance and feeling of my skin.
Uso la vitamina C da molti anni ma non sono mai riuscita a trovarne una veramente adatta alla mia pelle. Alcune erano troppo appiccicose, altre addirittura si ossidavano sulla mia pelle, facendomi diventare arancione... La svolta è arrivata quando ho sentito una persona su Instagram parlare della vitamina C di Geek & Gorgeus e ho deciso di provarla... SPETTACOLARE! È la vitamina C perfetta: liquida, non appiccicosa, si assorbe subito. Per me da 10 e lode!
Ho provato diversi sieri alla vitamina C . Questo è in assoluto il migliore. Uso questo siero tutte le mattine e dopo un mese la mia pelle è cambiata. Mai più senza!
