If you meaning shaving the face there are a few reasons why it can do some good. For one, it looks better on most men. Another reason is that it is more hygienic as beards can trap food, etc. Beards can also cause acne, as you might not be able to wash your skin as easily, it also can't breath as easily, and won't absorb moisturizer as readily. Another great reason to shave is it can actually prevent aging somewhat. Have you ever noticed that men at the same age as women tend to have firmer more line free skin? This is because men are exfoliating their skin daily while shaving, not allowing wrinkles to form, because they remove some of the top layer of the skin. Though, of course, some people find beards and facial hair very attractive, and some men look better with it than without. Say you have a weak chin, a beard can often make it look as though it's bigger. If you have big fishy lips you don't like a mustache can hide them and make them appear normal.
