I bought this duo primarily for the C serum, as I wanted to see how it compared to a few of Skin Ceutical's C serums (CE Ferulic, 20% AOX, Silmarin CF). It's less oily, less moisturizing, less smelly, and it doesn't leave as much of a sheen on skin after it's absorbed/dried. Does it work better than Skin Ceutical's serums? I am not sure, though I assume it's as effective, as I haven't noticed much of a difference in my skin. I think this product would be great for people with oily skin or who don't like a sheen after applying a C serum.
