I did it everyday for a week at night. I made a blend of 30% castor oil, 70% sunflower oil. After I cleanse, I'll dab a bit of tea tree oil on any existing blemishes and then moisturize with jojoba oil. In the mornings, I only wipe my face with a warm wash cloth - no cleanser.
I've since gotten a Clarisonic, so I'm still feeling out my routine. I think I'll do OCM a few nights a week now. When I don't use OCM, I use iS Clinical cleanser, which is very gentle.
GL if you try it! I love what it's done for my skin so far!
