Our take on the Obagi C Fx C-Clarifying Serum

Obagi C Fx C-Clarifying Serum is a vitamin C serum built around arbutin, made for uneven tone, dark spots and fine lines. It is the clarifying step of the Obagi-C Fx system and is hydroquinone-free. The best new price is $108.75 at Obagi as of November 5, 2026, and only one store lists it new, so there is no cheaper new option to compare against right now.
