Hi Peri
How did you get the Infopack to download? I'm still hassling around trying to provide them a website in order to be able to do it!!
I looked at that House of Deming website. Sure enough, their Cetic-16 C serum contains l-ascorbic acid, but look at what they have to say about it:
"Vitamin C (Ascorbyl Palmitate/Palmitic acid ester - Vitamin C) a natural antioxidant derived from Vitamin C and Palm oil. Most skin care products contain the most common form of Vitamin C, L-absorbed Acid, which is only water soluble (& not Fat soluble) meaning it will never penetrate into your skin, and thus it's ineffective. Only Vitamin C as Ascorbic Palmitate is both fat and water soluble, and able to be absorbed by the skin. All of PureDeming's products that include Vitamin C use only this form of Vitamin C. This form of Vitamin C is essential for the production of collagen and it also assists in healing inflammations and promoting the growth of collagen, which in turn, firms the skin. Additionally, it is essential in the prevention of collagen break down, resulting in combating the signs of aging. There is much confusing over which form of Vitamin C to choose: L-ascorbic acid or Ascorbyl Palmitate. L-ascorbic acid is sensitive to formulary concerns, including concentration as well as the pH level needed for it to remain stable, thus most topicals containing Vitamin C in this from are ineffective [they are not high unstable and inconsistent, thus you do not receive the benefits of topical Vitamin C. Though it is most often used as it is much more inexpensive then Ascorbyl Palmitate]. Ascorbyl palmitate, which is stable, has none of the product degradation concerns that L-ascorbic acid does, this is, also, why our products use this form of Vitamin C. Note: in our Cetic-16 we use pure Vitamin C, in the form of L-ascorbic acid. There are no stability problems given when the consumer gets the product, they add the Vitamin C powder to the premix base, thus ensuring its effectiveness."
What's up with that???
