I love coconut oil, I use it pretty much daily on my face. I agree about getting the extra virgin coconut oil, and "expeller pressed" too, if possible (which means it was not extracted with chemicals, it was just squished out).
You can get it at the health food store in the food aisle. I like the Nutiva brand, it is inexpensive, extra virgin, certified organic and expeller pressed, which as natural as you can get. You can find coconut oil in the cosmetic/skin care section as well, for a much higher price, but since it is exactly the same thing with different packaging, why pay more?
