Clean shaven is a style, not an absence: it exposes every line of the face and asks the bone structure to do all the work a beard would share. It reads as youthful and open, formal enough that some workplaces and militaries still require it. It is also the "before" in every before-and-after on this site: seeing your face bare next to a style is what makes the choice informed.
Who does it suit?
Shows off strong jaws and balanced features; on soft or round faces, a shadow of stubble often frames better than bare skin.
How to maintain it
A proper shave every one or two days: warm water, sharp blade, with the grain first, moisturizer after. Razor burn is the style's only enemy.
