Vitamin C is third in my list of all-time skincare ingredients, second to only retinoids and sunscreen. Since vitamin C as L-ascorbic has been proven to do everything from lightening sunspots to enhancing collagen production, to evening out skin tone to preventing future UV-induced skin and hair damage (International Journal of Pharmaceutics; Cosmetic DermatologyBritish Journal of Dermatology).

Unfortunately, vitamin C as L-ascorbic acid is also very unstable in the presence of light, heat, and air. Anyone who has purchased a 1 oz or larger dropper bottle of vitamin C knows that the product can become yellow, dark, crystallized, or hardened as the vitamin Ctherein oxidizes and is no longer as viable. (Although rumors persist on the internet that vitamin C can become pro-oxidant and thereby harmful to the skin, this has been refuted, see blog post here.)

That said, the following forms of vitamin C currently exist:

Even so, I remain skeptical of many forms of vitamin C, because they need to be formulated at a pH of 2.0 to 2.5 to be absorbed into the upper layer of the skin maximally (Journal of Biochemistry, 1993; Dermatologic Surgery, 2001), and then there’s that concentration and conversion issue — you might need 20% of a vitamin C + fatty acid compound to be equivalent to 10% L-ascorbic acid, plus the former still has to be converted to L-ascorbic acid. Considering that we don’t always metabolize properly, I don’t feel right declaring “a perfect 20% ascorbyl glucosamine converts to 10% L-ascorbic acid” every time.

Is Vitabrid CG the Ideal?

The ideal form of vitamin C would do three things:

  1. Penetrate the skin as deeply as tetrahexyldecyl ascorbate;
  2. Convert to L-ascorbic acid quickly, or contain L-ascorbic acid therein, like 3-0-ethyl ascorbic acid;
  3. Be more stable than early L-ascorbic acid alternatives (like ascorbyl palmitate), in the way magnesium ascorbyl phosphate is.

More research needs to be done (in my mind) to confirm this, but Vitabrid CG thus far has the chops to seemingly hold up to these standards. Developed by world-renowned chemist Dr. Jinho Cho, the main component of Vitabrid C12 products, Vitabrid CG is not so much a new form of vitamin C as a delivery and preservation system. Vitabrid CG delivers active, stable Vitamin C through multiple layers of the skin through a patented Layered Double Hydroxide (LDH) Technology. The parent company states this allows vitamin C to be delivered into the dermis (deepest layer of the skin) continuously for over 12 hours.

How To Use

After cleansing your face, you add 1/2 a teaspoon of powder to either water or your favorite toner/serum. You mix well, and then you apply it all over your face.

It doesn’t specify how much toner/serum to use with the powder. I started with a dime-size amount, and it made my skin feel a bit chalky. The next time, I added the booster to a quarter-size amount of toner/serum, and that felt better on my skin — smoother, and more absorptive.

I personally am not a huge fan of boosters, but I do like the promise of Vitabrid C12. I guess I don’t like boosters because they’re messy. (I’m messy enough on my own without having a powder contributing!) I also don’t like boosters because know all that goes behind formulation, and everything from pH to viscosity to volume of product makes a difference in the potency of an active ingredient. That said, I would only use a vitamin C booster in a vitamin C serum, and never with retinoids (which require slightly higher pH levels for optimal activation) or niacinamide.

Bottom Line

Although I’m not a huge fan of boosters and do not mix vitamin C with niacinamide (and Vitabrid C12 has 5% niacinamide), I tried the Vitabrid C12 powder mixed into a favorite vitamin CE serum.

Overall, I loved the idea that it was getting vitamin C delivered into the deepest layer of my skin and that it had a heightened level of stability. I would like to try other Vitabrid C12 products that don’t have niacinamide in them, and which weren’t booster powders to begin with. That said, it seems to be a good product, and I’m excited for the future of Vitabrid CG and what products it will be found in next.
