Welcome back to part four of my Vitamin C Skin Care Series. As we all know, eye creams are important for toning, firming and tightening up the sensitive orbital area of your eye. That's where you first begin to see fine lines and signs of aging. Here are three vitamin C-infused eye creams that help to stunt the aging process and keep your eyes looking taut and smooth.

Jan Marini C-ESTA Eye Repair Concentrate ($77) is a medically tested eye treatment to help significantly slow down the signs of aging around the thin-skinned areas of your eyes.

It is suitable for all skin types and contains a high concentration of vitamin C. Apply just a little bit to your lower and upper eye area, stopping at the crease.

Rejuvenal-C Orange Eye Pads ($4) are infused with orange, vitamin c, ginkgo biloba, green tea, and chamomile to tighten, calm and reduce puffiness in your eyes. The package contains five pairs of eye pads that are safe for all skin types.

It is recommended to take out contacts before use. Simply place a pair of pads over your eyes and relax for anywhere from ten to thirty minutes while "the C" works its magic. For a treat, try chilling the pads—it's refreshing and enjoyable.

N.V. Perricone M.D. Cosmeceuticals Vitamin C Ester Eye Area Therapy ($50) is an eye serum that nourishes and restores balance to your delicate eye area. Use in the morning and at night for maximum benefits. After a week or so, you should begin to notice a change in tone and texture in your skin.
