All You Need to Know About Ascorbyl Glucoside

What is Ascorbyl Glucoside?​

This is probably among the famous Vitamin C derivatives in skincare industry. People usually address this ingredient as ascorbyl glucoside but in some cases, we can see people name it as AA2GTM. It is a specific derivative of vitamin C with glucose added to the  side chain and is known or its high stability under exposure to heat, light, air and water. AA2GTM stands for ascorbic acid 2-glucoside. This ingredient existed mainly due to vitamin C instability due to many factors. Before we go deeper about Ascorbyl Glucoside, let’s get to know about Vitamin C or its chemical name is Ascorbic Acid.

All About The Famous Skincare Antioxidant: Vitamin C

Vitamin C or Ascorbic Acid is one of the famous potent antioxidant in skincare industry other than glutathione, niacinamide, vitamin E and others. You can read more about antioxidant role in skincare in this ENTRY HERE.

Antioxidant helps fight free radical damage on your skin in which these culprits accelerate your skin’s aging, making wrinkles and fine lines to appear faster than your actual age. This ingredient also provides brightening effect to your skin by increasing collagen production for firmer and younger-looking skin. 

However, formulating skincare containing Vitamin C is hard since this ingredient is extremely unstable in the presence of light, air, high water content and high pH. The instability will accelerate oxidation of vitamin C, causing the solution easily turns into dark orange to brown colour. Oxidized product does not harm your skin but it will no longer give effect to your skin as what the skincare claims. Hence, opting for Vitamin C derivatives would be the best choice to reap vitamin C benefit while formulating stable Vitamin C form in a finished product.

Reasons Behind Ingredient Upgrade of ZarZou Beauty

Due to Vitamin C instability, ZarZou Beauty has upgraded the Vitamin C in the old formulation of Brightening and Hydrating Facial Serum to Ascorbyl Glucoside

Based on research in 2012, ascorbyl glucoside is found to have high stability, making it difficult to oxidize like pure ascorbic acid. For those who are scared of getting purging (not to confused with breakout. Read here for the differences between purging and breakout), this ingredient is for you as it is not as potent as pure ascorbic acid that increases cell turnover and accelerates outbreak of existing acne. You can still reap same brightening, antioxidant and anti-aging effect just like from ascorbic acid.
