One of the primary reasons that men’s faces seem to age better than women’s is that men exfoliate their skin with safety razors. Now, an increasing number of women are shaving their facial hair to gain the same benefit. While this may seem to be a somewhat odd (and even counterproductive) habit, notable women such as Elizabeth Taylor and Marilyn Monroe reportedly shaved their faces. Contrary to popular belief, shaving does not encourage women’s facial hair to grow back thicker. Cutting off hair at the skin’s surface does not cause hair to change on a cellular level, and removing fine facial hair will not result in thicker, darker hair unless it was there to begin with. On top of that, shaving with a razor mechanically removes the top layer of skin. This form of exfoliation promotes collagen production and removes fine wrinkles, which makes facial skin look younger.
