What Is Vitamin C?
Vitamin C, also known as l-ascorbic acid in its pure form, is a powerful antioxidant and skin brightener. It helps neutralize free radicals and reduces cell damage caused by the environment.
The Benefits of Vitamin C for Your Skin
Free radicals are unstable molecules triggered by a variety of environmental factors, including sun exposure, pollution and smoke. When free radicals are exposed to the skin, they start to break down collagen, so skin can show more obvious signs of aging -- wrinkles, fine lines and dry skin. To protect your skin and form a barrier against free radicals, you should wear a broad-spectrum SPF every day. Topical antioxidants, such as vitamin C, can provide an extra line of defense.
What to Look for in a Vitamin C Product
Look for a steady concentration of vitamin C to avoid skin irritation, and make sure the formula you choose comes in a dark bottle to avoid exposure to light, which can lead to oxidation, making it less effective.
