Vitamin C has long been hailed as the immune system's best friend when it comes to fighting winter colds, but as it turns out, it can also make you look really good, too.
"Vitamin C is integral in the production of collagen, which prevents the thinning of the skin," says Dr. Neal Schultz, the New York City dermatologist behind skin care brand BeautyRx. "It also causes the oxidation of existing melanin and inhibits the enzyme that makes new melanin, so it both fades existing hyperpigmentation and prevents new hyperpigmentation—and you're left with brighter, softer skin."
When incorporated into a skin-care routine, vitamin C has both anti-aging and brightening properties, so it can be used to prevent and treat wrinkles, redness, dark spots, and a general lackluster appearance. Get enough vitamin C, and you'll look and feel your best.
But don't try to make a mask out of Emergen-C and call it a day (seriously, don't). Since vitamin C is water-soluble, it needs to be specially formulated to penetrate the top layer of the skin and work its magic.
