Coconut oil. I discovered it through my reading and then learned that my grandmother in the Philippines used it too. It doesn't just moisturize the skin, it seems to heal it. Maybe it's the medium chained fatty acids. Amazing stuff. Natural, cheap, edible. I don't want to put anything on my skin that isn't actually edible. We soak stuff up through our skin-that is why nicotine patches work.
I've written some beauty hubs, if anyone wants to check them out.
