I haven't found the pH posted online or on the SkinCeuticals website, but I would assume it is around or below 3.5.

SkinCeuticals was a pioneer of ascorbic acid (Vitamin C) in skincare, and their Duke research in the 1990s found that a pH below 3.5 is optimal for its absorption. They actually have a patent on 3.5 pH cosmetic products containing ascorbic acid--according to the Duke Antioxidant Patent, they are the only company that can make ascorbic acid products at this pH. This product falls under the Antioxidant Patent, which leads me to assume that the pH is optimized for this product, and that the pH is likely at or below 3.5.

Cheers!
