I just had to reply to this thread: I read this a few weeks ago and was quite skeptical. Then I received a sample of deep cleansing oil from DHC, and thought, if there are women who will pay $25 for a commercial product, there has to be some merit to it!
So the sample has lasted 3 days, and I love it. No blackheads coming out yet, but the product instrux say to rinse with cool or lukewarm water. It's so light, too; I just have to rinse my hands and the oil comes right off. Then I wipe it off my face with a warm washcloth. I came back to this thread to check, because I was pretty sure I remembered the water should be "as hot as you can stand it."
So now I'm off to my co-op and hfs to try to find castor, coconut and rosemary oils. I have extremely dry skin, esp in winter, so plan to go easy on the castor. The DHC stuff is olive and rosemary (plus whatever else they won't tell me) and it's been working great. Takes my makeup right off, leaves my face feeling moist without an oil slick, but I do apply my Oil of Olay night cream when I'm done. In the morning, I rinse with water and apply my Olay with SPF.
I'll post an update with my experience, too.
