So, you’ve heard that you should add a topical Vitamin C into your skin care regimen. It can help defend against skin aging, fortify against sun damage, help your skin retain moisture and so much more. But what kind of topical Vitamin C is the best, you ask? Here’s the thing: not all topical Vitamin C is created equally.

Obagi’s Professional-C® line uses L-Ascorbic Acid (pronounced L’ uh-skor-bik-as-id), which is known not only as the most potent form of Vitamin C, it’s also the most bio-available – a.k.a powerful – form. It’s a powerhouse antioxidant that protects against damage caused by harmful molecules called free radicals, as well as environmental pollutants.

 

But how does L-Ascorbic Acid work?

Vitamin C neutralizes free radicals, such as UV rays and air pollution, helping to reduce their damage to the skin. Furthermore, studies have proven the skin benefits of Vitamin C and confirmed that it can fortify the skin’s defenses against environmental stressors and minimize the appearance of fine lines and wrinkles.

However, with all its benefits comes a catch: While L-Ascorbic Acid is more powerful than many forms of Vitamin C, it is also unstable when exposed to light and oxygen. So when searching for an L-Ascorbic Acid serum, it’s important to look for a formula with a base that will provide the best protective environment to uphold its potency. The good news is, Obagi Professional-C Serums use L-Ascorbic Acid in a special stabilized base that enables it to absorb and remain in the skin to offer maximum antioxidant benefit. Our Professional-C Serums are available in 3 strengths for different skin types and needs.

Topically, L-Ascorbic Acid is found in Obagi’s Professional-C serums in concentrations of 10%, 15%, and 20%. You can apply a few drops of the serum to the face, neck, and chest every morning right after cleansing and toning to start gaining the beneficial properties of Vitamin C. Check with your skin care physician to see if one of our Vitamin C serums would be a valuable addition to your regimen.

 

Obagi’s Professional-C Microdermabrasion Polish + Mask also offers an unparalleled level of 30% L-Ascorbic Acid and helps to exfoliate and immediately reveal more luminous skin.
