Vitamin C Forum

And now, there's a new formulation to add to the list: powder. Because vitamin C is known for being unstable in many skin care products—it oxidizes little by little every time the bottle or jar is opened, making it break down and become less effective—brands are trying to find more stable compounds of the ingredient, as well as newer methods of delivering it into the skin. This is where topical powders come into play.

As experts in Vitamin C skin care, Kiehl's has long understood the benefits of the ingredient and demonstrates extensive expertise in incorporating this potent ingredient at beneficial concentrations.
