An anti-oxidant is a molecule that helps prevent something from being oxidized. Normally in the human body there are many processes that result in oxidation (just from the mere byproduct of living and breathing), but too much oxidation in your body results in damage and with a proper diet of vitamin C (commonly found in citrus fruits in lemons, lime, oranges, etc) you can minimize it. Thus eating a diet rich in vitamin C will give your skin the nutrients needed to stay healthy.
2. Vitamin C helps with the production of collagen.
With a proper diet of foods rich in vitamin C you can have enough vitamin C so that your body can produce collagen (proteins in your body that give your skin flexibility and strength). With enough production of collagen, your skin will stay strong and durable.
3. Vitamin C efficacy can be destroyed easily
Being near copper, boiling, cooking, pasteurization (a process that slows the microbial growth in foods such as milk) will destroy any vitamin C in the item, so its best to be careful on how you prepare foods rich in vitamin C.
4. Vitamin C is unstable.
The very virtue of Vitamin C being a antioxidant gives it ... its very nature to be unstable. Left just being exposed to air will oxidize vitamin C and will make the very potent effects of vitamin C rendered useless. So that's why products such as the Cellex-C Advanced C Serum are kept in a glass polarized glass bottle to prevent sunlight and other things from oxidizing its contents.
5. Vitamin C can prevent scurvy.
Scurvy is a disease that afflicts people with a deficiency in vitamin C making their connective tissues begin to fail and some bleed to death due to it. In the past, the main people who had this disease were people who were out at sea for extended periods of time such as sailors and pirates who tend to be out at sea longer than the supply of fresh fruit can be transported.
6. Vitamin C can be obtained in meat.
Chicken, beef and pork livers are an excellent source of vitamin C, however cooking them too much will destroy any efficacy of it in your diet.
7. Vitamin C can be produced in most animals but not humans.
Most plans and animals can produce their own supply of Vitamin C in their bodies. Thus do not need to necessarily have vitamin C in their diet. However people are the few mammal species that need it specifically in their diet. Thus its important to have a ready source for yourself (ideally fresh) at all times.
8. Vitamin C is essential to many metabolic processes.
Many of your body's normal metabolic processes need a co-enzyme (such as vitamin C) to create the byproducts that of which we need to live. Without these your skin can suffer.
9. Vitamin C in vitamin tablets or capsules is a poor source for Vitamin C.
Due to the limitations of how much your body can absorb at one time plus the fact that your stomach is full of acid to destroy much of the potency of vitamin C, your best bet to either apply vitamin C directly to where you need it with a proper skincare products or have it in your diet where the digestion process will allow for your body to absorb the nutrients more easily.
10. There is such a thing as too much vitamin C.
Having too much vitamin C in your diet can be the cause of diarrhea (intense more liquid bowel movements). This may flush out nutrients in your diet that may not have been absorbed fully and also the loss of water in your diet. All of these things will affect the health of your skin.
