Lipid Soluble Vitamin C – Tetrahexyldecyl Ascorbate
I have written a fair amount on Vitamin C and its numerous benefits for the skin as can be seen with the following blog articles: Vitamin C Serum, Vitamin C Quick Reference Guide, Vitamin C in Skin Care Products and Why Use Vitamin C in Your Skin Regime. All of these articles can be found at: Vitamins For The Skin.
So the question is how many more articles can we write on Vitamin C and the answer very simply is not many more. All its benefits, uses and recommended products are mentioned in the above blog articles but I thought considering we are running a Dermaquest C Infusion promotion this month we should visit the unique ingredient that is being used in the C Infusion Serum: TETRAHEXYLDECYL ASCORBATE.
What Is Tetrahexyldecyl Ascorbate?
“Tetrahexyldecyl ascorbate is a form of vitamin C that’s been modified to be more lipid soluble.” Dr Alek NikolicThis modification allows it to better penetrate the skin. The problem with most topical forms of vitamin C is they’re water soluble and can’t make it through the lipid-rich skin barrier to reach the dermis of skin where they could have maximal benefits. Tetrahexyldecyl ascorbate is able to successfully penetrate the epidermis and move to the layer underneath called the dermis. It’s in the dermis that collagen, a protein that gives skin its youthful firmness and ability to resist wrinkles, is made.
Why Choose a Skin Care Product with Tetrahexyldecyl Ascorbate?
In my opinion and looking at new study results this should be our go to topical Vitamin C ingredient.
“The best, most stable, non-acidic form of Vitamin C is Tetrahexyldecyl Ascorbate (abbreviated THDA or THD Ascorbate).” Dr Alek Nikolic
Tetrahexyldecyl Ascorbate Summary of Skin Effects:
- An oil-soluble form of Vitamin C that can penetrate the lipid bilayer
- Retained in the epidermis and dermis (whereas Ascorbic Acid passes through), forming a reservoir of Vitamin C
- Its antioxidant action is 80 times longer than Ascorbic Acid because it is a slower free radical scavenger
- It has a two-year stability
Common Forms of Vitamin C:
- Ascorbic Acid (L-Ascorbic Acid)
- Ascorbyl Palmitate
- Sodium Ascorbate
- Sodium Ascorbyl Phosphate
- Magnesium Ascorbyl Phosphate (MAP)
- Tetrahexyldecyl Ascorbate (THDA) (also denoted Ascorbyl Tetraisopalmitate)
- Ascorbyl Glucoside
- Ascorbyl Glucosamine
- Ascorbyl Methylsilanol Pectinate
I hope you found the article on Tetrahexyldecyl Ascorbate interesting and valuable and that it gave you a new insight in the different types of vitamin C that are available and their specific strengths and weaknesses.
