The nose can be changed with cosmetic surgery, but the distance between the bottom of the nose and the upper lip is unlikely to change. This area is usually about one-fourth of the distance between the base of the nose and the bottom of the chin in males and about one-third in females. The filtrum is the groove that extends from the bottom of the nose to the top of the upper lip. It can be wide, deep, narrow or shallow. This area can be concealed by a mustache to some extent, but the actual distance cannot be concealed. Observe the nostrils carefully as they can be shaped in a variety of ways. Are they straight across? Do they form an angle with the sides higher than the center or with the center higher than the sides.
