According to the U.S. National Library of Medicine, “normal skin contains high concentrations of vitamin C, which supports important and well-known functions, stimulating collagen synthesis and assisting in antioxidant protection against UV-induced photo damage.” As you age and through exposure to external forces like smoking and the sun, your levels of vitamin C in your skin decline, leaving it vulnerable to wrinkles and age spots. Enter vitamin C products, creams and serums.

Perfect for all skin types, these topical treatments will help increase production of collagen and protect the skin from sun damage and dark spots while leaving skin glowing and help fight signs of aging, according to prevention.com.

When choosing the right product to use, keep in mind that “you can maximize the benefits of vitamin C by combining it with other antioxidants,” according to cnn.com. “This works best with vitamin E and ferulic acid.” Always consult your doctor prior to adding a vitamin C product to your skin care routine.
