Using Stabilized Vitamin C (AA-2G) with Zinc PCA

Regarding the use of Zinc PCA with Stabilized Vitamin C (Ascorbyl Glucoside or AA-2G), it is not recommended to combine these two ingredients in the same formula.

Based on the product information for Ascorbyl Glucoside (AA-2G Stabilized Vitamin C), formulas containing AA-2G should not include Zinc PCA as it can negatively affect the stability of AA-2G.

Ascorbyl Glucoside (AA-2G) is a stable form of Vitamin C that is generally well-absorbed by the skin on its own, similar to Ascorbic Acid, due to its molecular structure.

Therefore, you do not need to use Zinc PCA to enhance the absorption of AA-2G, and doing so would actually compromise the stability of the AA-2G.
