Using multiple formats of Vitamin C provides the most effective results for skin goals such as brightening and reducing the appearance of dark spots. We choose ultra-stable formats that act at different speeds (short, medium, long) and have different solubilities (lipid-soluble, water-soluble) so that we can select the formats that will work best for your skin.
Because every form we use is ultra-stable, there is no need to package our formulas in dark bottles. One of the most commonly used forms of Vitamin C by other brands (ascorbic acid) is known for instability, which has led to the misconception that all Vitamin C products should be stored in dark bottles to avoid light damage.
