Ingredient Feature: L-Ascorbic Acid
Blueberries, oranges and, most recently, the acai berry have gained popularity in our constant effort to seek out the answers to achieving optimal health. Known for their powerful free-radical fighting abilities, antioxidants are already finding their way into your morning smoothie or breakfast bowl, but did you know when applied topically, antioxidants can be helpful in fighting free radicals and in helping to improve the appearance of your skin?
L-ascorbic acid, the most widely known form of the antioxidant Vitamin C, has been described by many as the secret to flawless-looking skin*. It’s known to complement new collagen production and is also effective in reducing the appearance of fine lines, wrinkles and photoaging of the skin.1,2
The function and popularity of ascorbic acid has evolved over the centuries. Its first use in the 1700s and the origin of its name was actually to treat scurvy; “ascorbic” literally means “against scurvy.” At that time, it was ingested to treat and prevent the disease but later research showed that ascorbic acid could be helpful in cosmeceuticals as well. However, in order to be most beneficial to the skin, it must be in the L-ascorbic form, which, while effective, is equally difficult to stabilize.3 Unfortunately, once it is degraded, L-ascorbic acid can no longer carry out its beauty benefits and its effectiveness in fighting free-radical damage.4
The good news is that Obagi’s fan favorite, the Professional-C™ Serums, provide L-ascorbic acid in a bioavailable form for optimal skin absorption and results. In fact, they are some of our staff member’s favorite products too—they can’t help but rave about them wherever they go! With three different strength levels to choose from, Obagi has a Professional-C Serum for every skin type—dry, irritated, sensitive, normal, or oily.
