Well, I've been living on the road for almost two months now and I thought I would share an update on how all this oily face thing has worked out.
Turns out it isn't a problem AT ALL. In fact, it is less of a problem than it has ever been in my entire life.
I wipe my face down (starting with my eyes) with an un-scented, alchohol-free baby wipe (I use the Parent's Choice brand at Walmart), then I wipe my face with a slightly-dampened microfiber cloth.
That's it. I only have to do this twice a day. Once when I am changing clothes in the morning and once at night. This is actually less often than I used to have to rinse my face with water in the bathroom sink every day. My face doesn't get nearly as oily as it used to. Now, I lived in Tucson for over two years, and I still had the oily face problem when I lived there. So I am convinced that it is NOT the dry air that is making my face not get oily. I am convinced that my face was only getting so oily because I washed it every day. I did not use particularly harsh soap to wash my face. Nor was the soap especially made for oily skin. I just used Lever 2000 for everything.
Now, if I do not wipe with water, then whatever is in the baby-wipe will start to bother my eyes in about 8 hours or so. If I wipe with water, then my eyes never burn at all (remember my face-oils used to burn my eyes about 6 hours after normal washing), and I'm good all the way through to the next time I "wash" my face.
So the whole notion of not NEEDING to wash every day is not about learning to live with being dirty. It truly is about how human skin just doesn't need to be (and doesn't want to be) washed that damn often.
As to the microfiber cloth. If you have used one, you know that they don't want to absorb water if they are completely dry. So, I dampen my cloth by putting about 2 tablespoons of water in the bottom of my measuring cup, wadding up the cloth, stuffing it into my measuring cup, and letting it sit for a while. If I start the "cloth dampening process" just before I start washing up then it is ready to use by the time I finish my other washing up stuff. Usually in about five minutes. After I wipe my face, I just hang the cloth over my steering wheel to dry and use it again next time. The baby wipe has gotten all the dirt off my face and the cloth doesn't really accumulate any dirt at all. So, all total, I'm using about 4 tablespoons of water per day to wash my face. You can't beat that with a stick.
