Some of you have asked about the preservatives used in the Carolyn’s Facial Formula™ skin care line. We do not use the usual “chemical” preservatives found in most skin care products. In fact, our system works in at least two beneficial ways. Our harmoniously-working preservative method not only keeps our products fresh for up to 18 months, it has the added benefit of promoting healthy and healing properties for the skin, as well. For example, we use neem oil as one of our “preservation” ingredients. It has anti-microbial properties helping to keep the product safe from bacteria as well as restoring, rejuvenating and repairing damaged skin.
