Condensed from Ein Ayah, Shabbat 8:42 Smoothness, Youthfulness, and Purity
An early state of development in the vegetable world has its impact even on the human body, because they share the characteristic of growth and therefore the former can give a style of youth to the latter. That is the reason that smearing premature olive oil on a woman’s skin will bring back youthfulness or reverse premature aging. The purity of youth and the balance of their constitution along with the lack of “strong heat” cause hair not to grow [throughout the body]. This lack of hair is an element of true beauty, whose inner characteristic is of aesthetic adornment, which indicates proper qualities. It is proper that when one strives for such a standing, it should make its imprint in such a manner that all will sense the beauty. The internal purity of the characteristics is that which causes the skin to be smooth, including possessing a charm of spiritual fineness. This is an attribute that is well beyond the coarseness of animalism, which gives the skin a sign of moral ugliness, which is the opposite of smoothness.
