I do this on a weekly basis, and I have noticed a big difference in my skin. It is more even-toned and radiant. Thks for sharing this tip. I was just about to buy the body shop vit c serum when I read this article of your's and it saved me a lot of money.

Vitamin C is a natural reducing agent and can lower the overall oxidative state of an environment (i.e. your skin) and when used judiciously can combat some of the mechanisms of aging. But when present in concentrations exceeding 300 ppm you get into the "too much" region(and of course there's tons of issues of "what amount corresponds to 300 ppm", and how thickly a person applies a product, and so on and so on). Your best bet to lower your oxidative state? A good diet. It's similar with the chemical sunscreens. They can hold onto a radical for a while and keep it from penetrating and damaging the DNA in your (live) skin cells in lower layers of skin, but they also seep into your skin (or so I've read; can't say that I've done work in this area) and if you skip a day, then the sunlight you're exposed to on the off day will penetrate the lower layers of skin and sunscreen from previous days' application will hold on to the radical for a longer amount of time (same as it always does) except this will take place in the derma, making it more damaging. So (again, what I've read) it's best to use sunscreen, but to use it religiously. It’s a question of the antioxidant nature of the vitamin C.

Doesn't d-ascorbic acid actually cause irritation and increase production of free radicals? I have searched long and hard to find an affordable preparation of vitamin c that contains only the helpful l-ascorbic acid in a stable form. I think I finally found something (http://www.woodridgelab.com/products/perfectC.php) but it is about $30 a month, which is hard to justify unless d-ascorbic acid is less harmful than I realize. Also the l-ascorbic acid is delivered via a silica powder. I'm certain the silica particles are more than 4 microns. Should I be worried about silicosis? Can a product with dangerously large particles of silica be approved by the FDA? What about isomers? Doesn’t d-ascorbic acid actually cause irritation and increase production of free radicals?

One problem that I am having is that my face breaks out more when I am using the Vitamin C. I have very oily skin and the Vit C application really slows down the oil production but increases the breakouts. I was wondering why that is and if anyone else has encountered the same problem....

Would it be just as good as the expensive BHA from Paula's choice?
