National Vitamin C Day

Vitamin C protects the skin from oxidative damage from exposure to light, heat, and pollution. SkinCeuticals, a company specializing in cosmeceutical treatments, created National Vitamin C Day "in an effort to raise awareness of the importance of vitamin C for health and beauty, to celebrate the brand's renowned, results-driven antioxidant serums and the importance of incorporating vitamin C into daily routines."

Dr. Sheldon Pinnell of SkinCeuticals undertook research about the delivery of vitamin C to the skin, and with it came the creation of the company's cosmeceuticals. Vitamin C Day is an annual celebration of this research and of the benefits of vitamin C. According to SkinCeuticals, the application of their vitamin C products to the skin corrects visible signs of aging, including fine lines and uneven skin tone, and also prevents future skin damage. SkinCeuticals is not without some credibility: According to the National Institutes of Health, vitamin C "holds promise as a mainstream drug in future dermatology practice."

Vitamin C, or L-ascorbic acid, is a water-soluble vitamin that's found in some foods and added to others and is also present in dietary supplements and topical applications. It is needed for the biosynthesis of collagen, L-carnitine, and some neurotransmitters, as well as for protein metabolism. It's a physiological antioxidant that regenerates other antioxidants, and it limits the effects of some free radicals, perhaps helping to prevent disease. It assists in immune function and in the absorption of nonheme iron, the iron from plant-based foods. Insufficient vitamin C intake can cause scurvy.

Fruits and vegetables are the foods with the best sources of vitamin C. Some with the highest amount are citrus fruits, tomatoes, tomato juice, red and green peppers, potatoes, broccoli, strawberries, kiwi, brussels sprouts, and cantaloupe. The vitamin C content of foods may lessen with cooking and prolonged storage. Steaming and microwaving are the best ways to cook foods with vitamin C to retain the vitamin. Groups at risk for vitamin C deficiency include smokers and those regularly exposed to secondhand smoke, infants fed evaporated or boiled milk, those with limited food variety, and those with malabsorption and some chronic diseases.
