Orange you glad your mom made you drink your OJ as a kid? Welcome to the first part of my five-part series on vitamin C and beauty. Lately, there has been a lot of hype about vitamin C in skin care, so l decided to find out about the benefits.

Apparently, it takes 24 hours for any vitamin C that your body digests to reach your skin and not nearly enough of it makes its way there. Hence, the popularity of topical treatments. Studies show that "C" helps with firmness and overall health of your skin, plus it's a great antioxidant that helps fight environmental damages! Looks like for a great complexion, orange is all the rage.

Darphin Arovita C Line Response Lifting Serum ($125) is a deliciously scented vitamin C face serum that stimulates the skin and helps it stop the signs of aging. It improves resilience, combats lost elasticity, gives your skin a nice glowy look and it helps reduce fine line and wrinkles. Use in the evening for a more intense treatment.

For two more vitamin C-enriched facial serums,

Natura Bisse C+C Vitamin Complex Concentrate Serum ($150) comes individually packaged in six vials. This intense repair treatment helps skin fight back against damage from sun exposure, pollution, free radicals and stress which wreak havoc on your face.

It's formulated with a high concentration of pure vitamin C for deep penetration. Also, it's a gentle skin lightener and it's perfect for smokers whose skin elasticity is suffering.

John Masters Organics Vitamin C Anti-Aging Face Serum ($30) is a facial serum that nourishes the skin with moisture, antioxidants and pro-collagen production. It is certified organic—for those of you who are interested—and the smell is really fresh and sweet.

Apply a few drops to your face and neck before bed and after your skin has been cleansed. Use slightly more product on areas that have been exposed to the sun. No moisturizer afterwards is necessary.
