C-Glow

Pure Vitamin C (or Ascorbic Acid) is a 3-in-1, clinically proven superstar that gives the skin environmental protection (antioxidant), boosts the skin's own collagen production and fades hyperpigmentation. This water-light formula contains 15% Vitamin C & extra antioxidants to give a healthy glow, even and firm the skin.

3-3.4 pH
15% Ascorbic Acid
+ Ferulic Acid Tocopherol

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, 8 months shelf-life. 

The official shelf life of C-Glow is 8 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 fresheven beyond its official 8 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.  

Everyone looking for a light-textured, pure Vitamin C + extra antioxidants formula. However, if you have sensitive, redness-prone skin, we do not recommend C-Glow due to its low pH and high pure acid content.

Skin Type: all skin types except for sensitive 
Skin Problem: dark spots, aging, dull and uneven skin
Texture: fast absorbing, water-like, weightless liquid

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: 8 months from production (unopened), 3 months PAO (period after opening).
