There is a lot to learn about when it comes to the subject of organic skincare preservatives, and for one, any certified organic skincare products will not use synthetic preservatives, but rather will use natural alternatives, such as citrus seed extract, potassium and Vitamins A, C, and E. Even though the percentage of synthetic preservatives used in conventional formulas is quite small, caution still needs to be taken because some people may still experience adverse or allergic reactions to them.
