Men and women differ not only in regard to emotional needs, but also in regard to physical appearance. The most significant differences between men and women are often seen in the physical traits and features of the face. It's not just one or two physical features that differentiate men's and women's faces, but a variety of factors that influence the development of feminine and masculine facial characteristics.

Female faces deemed anatomically attractive tend to be heart shaped, with rounded corners from the hairline that extend down toward the chin area. Males tend to have square-shaped faces with more intricate hairlines and slightly square jawlines. Males also tend to have longer faces at the bottom to accommodate a longer upper lip and lengthy chin. FacialFeminizationSurgery.info states that facial profiles of males and females differ as well. The profiles of women tend to be flatter, while the foreheads of men tend to slope backward and the lower portion of their faces tends to protrude forward.

Females' eyebrows are more arched and sit higher above the rims of the eyes, while males' eyebrows sit slightly above the brow bone. Often, men's eyebrows are also bushy and straight with no arch. Females have smaller, shorter-shaped noses with narrower bridges and nostrils. A female lip and the tip of the nose tend to point upward. Men have a longer distance between the base of the nose and the top of the lip. Females often have a backward slope between the top lip and the nose. Women tend to have eyes that appear larger, and the shape of the rim above the forehead influences the shape of the cheekbones.

FacialFeminizationSurgery.info states that brow bossing is more pronounced in men. Brow bossing is the horizontal bone ridge that runs across the forehead just above the eyes. Women tend to have foreheads that are more rounded and vertical. Women have fuller, rounder cheeks and they tend to have higher cheekbones than men do. Men tend to have hollower cheeks because they tend to have less fat. Men have wider jawbones than women do; this is because the muscles attached to the corners of the jawbone have a tendency to be more robust. Female jawlines form a soft curve that extends from the earlobe to the chin. Male jawlines are straighter from the ear downward and then more angular toward the chin.

According to Gettysburg College Professor Richard Russell, whose study appeared in 2009 (see Reference section), all female skin, regardless of race, tends to be lighter in color than male skin. However, females have higher contrasting features than males do. Lip color and eye color are darker among females, even though the color of their skin is lighter.

Females tend to have thinner skin than males do. GrowingBolder.com states that this is due to higher levels of testosterone hormones in males. In addition, men’s dermis and epidermis skin layers are thicker due to larger amounts of elastin and collagen. Also, men tend to have larger pores and oilier skin than women do.
