I first came across jojoba when I was looking into tea tree oil, primarily for foot care. Jojoba oil was mentioned as a good carrier oil for tea tree oil. Since then, however, I have heard very good things about the use of jojoba oil as an aftershave and beard oil, among other things.
One of the more perplexing things about jojoba oil is that it is not actually an oil. The distinction between wax and oil is not precise, but rather has to with the nature of lipids. Generally speaking, an oil is liquid at room temperature, whereas a wax is solid. A wax ester, however, results from condensation of a fatty acid and fatty alcohol.
