Cellex-C: Any Different from Other Brands of C?

Look at these before and after pictures.

They are of someone who has been using Cellex-C since she was 42. The first photo was taken when she was 30, and the second when she was 60. I've seen a lot of before and after pictures, but this one is intriguing because the "before" picture was taken when the woman was younger, and the "after" picture shows aging.  But it clearly demonstrates that the product works.

As someone who has used Obagi C  for years, and know that vitamin C does work, I'd like to try them both and compare. Cellex-C also contains zinc, and that may make it more effective than Obagi, which is simply a 10% C serum.

As soon as I get my hands on it, I'll let you know.
