Vitamin C Facts:
L-ascorbic acid is the only form of vitamin C that the body can recognize and use. A product must have a pH below 4.0 in order to be effective and penetrate into the skin. A product must have a minimum share of 10% L-ascorbic acid to changes in the skin (eyes, levels greater than 5% are not recommended) to create. However, the skin can not use more than 17.5% L-ascorbic acid. Water-soluble (L-ascorbic acid) vs. fat / fat-soluble (ascorbylpalmitate, ascorbyl magnesium, ascorbyl phosphate and sodium ascorbate)
These are different derivative forms of vitamin C and only a small percentage of the vitamin C will be delivered to the skin. Why? Because the size of the molecule is much larger and our bodies do not recognize these derivative ingredients. In order for our bodies to utilize the derivative form of vitamin C our enzymes must attack these lipid soluble molecules, resulting in at most 30% of the Vitamin C is delivered and used by the skin. Cellex-C provides 100% L-ascorbic acid on the skin.
Does this mean that other topical vitamin C products do not work. No, the work of other products topically to the skin as a moisturizer and antioxidants. They can not penetrate to the same level and therefore do not have the ability, reverse damage to the skin and rejuvenates the skin. Color Change-Oxidation is a natural occurrence that is a part of all the products thatcontain L-ascorbic acid. Even products that stabilized versions of vitamin C containing oxidized. Ex: Jan Marini, Skinceuticals.
Why does pH matter?
L-ascorbic acid is a pH of 2.0-4.0 have to penetrate to the skin. When the L-ascorbic acid acidýs pH is higher than 4.0 it is converted into D-ascorbic acid, and is not penetrated. Ex: Jan Mariniýs C-Esta has a pH of 5.0. We are very concerned about the pH values and% of L-ascorbic acid in our products to open, because they are very importantIndicators of the effectiveness of the products. Many lines not readily provide this information.
What is the shelf life of L-ascorbic acid?
Tests have shown that a product once opened 2nd % In May to lose 6-8 months, but that it is still effective and the product is still viable. (Some have said that the shelf life of ascorbic acid is only 3 weeks and that it is no longer correct after 3 months, as the concentration decreases by 10%. This is simply not have). Powder or crystal forms ofL-ascorbic acid, which can be effective with a diluent to mix. However, the formula may be different, because it can be difficult to obtain a homogeneous solution using this method.
The stabilization of L-ascorbic acid is relative. When the L-ascorbic acid is a perfectly stable derivative form, it is already associated with another molecule, for example, ascorbyl:. It is very difficult to break apart the molecules and to provide the benefits of L-ascorbic acid into the skin. There is no evidenceAscorbyl is anything but a good moisturizer.
Ester of vitamin C (as magnesium ascorbyl phosphate, ascorbyl palmitate, etc) are less than one fourth of vitamin C, the rest is the protective molecule. This means that you would need a significant amount of the ester to obtain a reasonable concentration of vitamin C in the skin. The absorption of L-ascorbic acid is an active process, not a passive process
