The term 'clean-shaven' refers to a person who has no facial hair. This can be described in three different ways: SMOOTH (6 letters), BEARDLESS (9 letters), and smoothfaced (11 letters). SMOOTH means having a surface that is free from irregularities, while BEARDLESS means having no facial hair, and smoothfaced means having a face with no facial hair. All three terms refer to the same thing - a person who is clean-shaven.
