Ultraviolet light results in photocarcinogenic and photoaging changes in the skin. Antioxidants protect skin from these radical changes.
The study from Duke University defines formulation characteristics for delivering L-ascorbic acid into the skin to supplement the skin’s natural antioxidant reserves.
L-ascorbic acid must be formulated at pH levels less than 3.5 to enter the skin. Maximal concentration for optimal skin penetration or absorption was 20%.
Delivery of topical L-ascorbic acid into the skin is critically dependent on formulation characteristics. This is why our formulation is so critical to how well the product will perform on the tissue.
By applying Anhydra (waterless) Ascorbic Acid (Vitamin C) Serum and Cream to the face, neck and body, where needed, the deep layers of the skin are stimulated to produce collagen at a high rate and reduce free radical at a high rate as well.
Other benefits of using Anhydra Vitamin C Body Cream are the anti-inflammatory and wound healing effects of L-Ascorbic Acid as well as its photo preventive effects against cutaneous malignancy.
With daily applications you will see the skin tone change and dark spots start to disappear and you end up with skin tone being the same coloring and skin tissue becoming thicker day by day as you thicken the collagen layer of the skin. This will help stop the tissue from bruising and browning with everyday movement.
As one of the most powerful antioxidants in the skin, vitamin C has been shown to protect against photoaging, ultraviolet-induced immunosuppression, and photocarcinogenesis. It also has an antiaging effect by increasing collagen synthesis, stabilizing collagen fibers, and decreasing collagen degradation. It decreases melanin formation, thereby reducing pigmentation. Vitamin C is the primary replenisher of vitamin E and works synergistically with vitamin E in the protection against oxidative damage.
Topical L-Ascorbic Acid (vitamin C) at 20% has a wide range of clinical applications, from antiaging and antipigmentary to photoprotective. The challenge lies in finding the most stable and permeable formulation in achieving the optimal results. This is what we have achieved to date. A stable topical L-Ascorbic Acid (vitamin C) at 20%.
Vitamin C is available in a number of active forms. Among all forms, L-ascorbic acid is the most biologically active and well studied. L-ascorbic acid is a hydrophilic and unstable molecule, hence the poor penetration into the skin. L-ascorbic acid is also a charged molecule, which further limits its penetration. Reducing the acidity of L-ascorbic acid to a pH below 3.5 is an effective method of improving its stability and permeability. This has shown to greatly aid its penetration, largely because of the transformation from the charged to the uncharged form of the molecule. The addition of ferulic acid aids in both stabilization of the molecule and achieving an acidity of a pH below 3.5.
