Look up "holy grail" in the dictionary and a bottle of the SkinCeuticals C E Ferulic ($166) will be next to it. I don't think I've met a beauty editor who didn't rave about this serum that uses a combination of ferulic acid and pure vitamins C and E to protect and treat skin from, well, every skin stressor you could imagine. The only con is that it's nearly $200, but most experts will tell you the proof is in the pudding, and the price is totally worth it. Copying Cline's routine meant I got a chance to revisit the formula I used years ago and, of course, it didn't disapoint. Warning: Cline is right, this does have a funky smell, but that's sort of its thing (it's free of synthetic fragrance that would otherwise cover up the scent, but potentially irritate skin).
