I used OCM for a while, and while it didn't bother my face, it didn't do much for my acne, either. I decided it was more effort than it was worth, and switched to WO.
WO really seems to have helped. I used to have extreme combination skin--an oil slick on my forehead, and peeling and flaking on my cheeks. With just WO and jojoba as a moisturizer (and sunscreen during the day) it balanced out nicely, and I noticed fewer breakouts.
These days, I use water in the morning (and am experimenting with various sunscreens), but I use water and a rosewater/glycerin toner at night (I'm using Burt's Bees right now, but will probably just make my own when it's gone). I'm also using From Nature With Love's Camelina Rosehip oil blend
at night, which has a bunch of carrier and essential oils that are supposed to be good for skin. I'm liking it a lot.
I do occassional (maybe once a week) masks with either aspirin or clay or an herb blend. If I get any pimples, I put a drop of tea tree oil on it and it usually goes away pretty soon.
This has all worked well for me, but everyone's different, so you might just have to experiment and see!
