epidermis and stratum corneum) to neutralize and protect
against free radicals such as sun and smoke, which are
environmental stressors that accelerate the visible signs of
the aging process
-
Unlike other vitamin C products, the vitamin C serum in the
Obagi-C Rx System is very stable and maintains potency longer
Proven, superior skin penetration.
Total absorption was calculated by adding amounts of L-ascorbic in the
reservoir, determined at .5, 1.5, 3.0, 6.0, 10.5 and 19 hours.

study, the vitamin C serum in the Obagi-C Rx System provided
50% more penetration into the layers of the skin to provide
greater antioxidant therapy and effectiveness.
