Why is it necessary to use vitamin C in the form of ester? Vitamin C can be delivered in many forms. The Perfect C has chosen to deliver vitamin C in the form of an ester that maintains its stability. Water readily oxidizes vitamin C. An ester creates an environment devoid of water, thus maintaining the stability of the vitamin C.
Why is lipid-soluble better than water-soluble in the case of vitamin C? Vitamin C is highly unstable when exposed to light and air. When vitamin C is in a water-soluble form, it is more susceptible to environmental exposure; as a result, it oxidizes more quickly. The nature of its water solubility only allows it to work on the outermost layers of the skin. Because it is so unstable, the water-soluble vitamin C has already started oxidizing by the time it reaches the skin, so a higher percentage is necessary to obtain any beneficial results. Since vitamin C can cause irritation when used topically, water-soluble forms tend to be more irritating because a higher percentage in the formula is needed.
How does the Perfect C's vitamin C work? The Perfect C is formulated with an emphasis on protection of the pure C and delivery into the deeper layers of the skin, using a silicone base to prevent the ester from breaking down. During topical application, two processes take place: The silicone base evaporates while the ester stays on the skin. The ester components split, making the pure vitamin C available for the skin to utilize. As a result, the following benefits are realized: Less potential for irritation because the C is lipid-soluble. Full benefits of the vitamin C percentage used (20%). Vitamin C is absorbed deeper into the epidermis than water-soluble C's.
Product Details: What makes The Perfect C different? The Perfect C Cream uses a stable, lipid-soluble ester known as Tetrahexydecyl Ascorbate. What does lipid-soluble mean? It is capable of being dissolved (liquefied) in fat/oil/lipids. What is the difference between oil-based and lipid (oil)-soluble? An oil-based product refers to the type of product emulsion: oil-in-water vs. water-in-oil. For example, a cream is typically an oil-in-water based product. A product base does not refer to ingredient solubility. Oil (lipid)-soluble refers to an ingredient's dissolvability. For example, salt can only dissolve in water; therefore it is water-soluble.
