Some of you have asked about the preservatives used in the Carolyn’s Facial Formulas™ skin care line. Rest assured, the “organically preserved base” used in the CFFormulas™ skin care line is a unique and innovative preservative system. We have combined the properties of rooibos extract, vitamin E, black willow bark extract, rosemary oleoresin and neem oil at specific levels that have created a synergetic preservative system. We also take even more effort to help preserve these organic products by using airless bottles and our dark blue, glass bottles to prevent oxidation and to keep them safe from light exposure. You can read more about the preservatives in CFFormulas™ on the Preservative Info webpage and the Ingredients Demystified page, as well.
