Have you seen the movie The Curious Case of Benjamin Button starring Brad Pitt, in which his character ages backwards? From an elderly man through middle age to youth, he grows younger and younger as time goes on. Unfortunately, aging backwards is not actually possible in real life, but diminishing the look of visible signs of skin aging can be! With an effective skin care regimen and a bit of perseverance, your skin can appear fresher and younger looking.

As we age, our skin doesn’t snap back like the way it did in our younger years, resulting in more signs of skin aging, such as the appearance of fine lines and wrinkles. L-Ascorbic Acid is the active form of Vitamin C and is proven to help reduce the look of fine lines and wrinkles.1,2 In addition, Vitamin C has been shown to help:  

  • Brighten skin3
  • Improve skin texture
  • Even skin tone
  • Defend against free radicals

Topically, L-Ascorbic Acid is found in the 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 before your sunscreen 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.

You might not grow younger (a la Brad Pitt), but your skin can certainly benefit from Vitamin C.
