Vitamin C is a powerful antioxidant that is used to create a brighter, smoother, more youthful complexion when applied directly to the skin in the form of lotions, serums or masks. According to the book "Cosmetic Dermatology," topical application of vitamin C may also protect the skin from the harmful rays of the sun, and help reverse the signs of aging by firming the skin and reducing wrinkles 3. You can purchase an over-the-counter lotion or serum containing vitamin C, or you can make a simple at-home facial.

Apply a moisturizer suitable for your skin type. Vitamin C creams and lotions may be slightly drying and may irritate sensitive skin.

Wear a sunscreen with an SPF of at least 15 every time you go outdoors. Although vitamin C may address some of the harmful effects of sun exposure, it isn't a replacement for sunscreen.

Homemade Vitamin C Facial

Place a small amount of oil in a cup or bowl. Oils that benefit the skin and serve as a carrier for the ascorbic acid include olive or sunflower oil. You can also use emu oil, coconut oil, jojoba oil or grape seed oil.

Stir in powdered ascorbic acid until the powder is completely blended. Use approximately 1 part ascorbic acid to four parts oil. Make only enough for one facial because the ascorbic acid breaks down quickly and loses its effectiveness.

Smooth the mixture over clean, dry skin and leave it in place for 30 minutes. Rinse the mixture by splashing your face with lukewarm water and then pat your skin dry with a soft towel.

Apply a light moisturizer followed by sunscreen with a SPF of at least 15. You can also use a product that contains both moisturizer and sunscreen.

Apply a fresh vitamin C facial every week.

Tips

Although you can apply vitamin C creams, serums and lotions in the morning, applying the product before bed provides time for the acids to fully penetrate the skin.

Ascorbic acid breaks down and loses its effectiveness quickly. Lotions and creams in opaque bottles hold up longer than products in clear bottles.

If possible, purchase products in pump bottles to minimize exposure to air.

Store topical vitamin C products in a cool, dry location when not in use.
