Sodium Benzoate is a preservative. It's used in both cosmetic and food products to inhibit the growth of mold and bacteria. It is typically produced synthetically.

Sodium benzoate works as a preservative by inhibiting the growth of bacteria inside of cells. It prevents the cell from fermenting a type of sugar using an enzyme called phosphofructokinase.

Studies for using ascorbic acid and sodium benzoate in cosmetics are lacking, especially in skincare routines with multiple steps.

Most effective vitamin C
This is the product I let myself splurge on because I haven't found anything that compares so far. This is so fast-acting for lightening my dark spots/acne scars. I use one pump on the whole face, once a day in the AM so the bottle tends to last me about 3 months. Highly, highly recommend for dark spots!
Did nothing for my dark spots, instead destroyed my skin barrier.
