Biologically, attraction is often about quickly identifying two things: health and gender. The features we unconsciously label as "feminine" are actually biological signals of high estrogen and youth.
Sexual Dimorphism: Men vs. Women
Key Term
Sexual Dimorphism refers to the physical differences between males and females of the same species. In humans, testosterone builds bone (brow ridges, square jaws), while estrogen builds fat deposits (soft cheeks, full lips).
The "Neoteny" Effect (Baby Face)
A key component of feminine beauty is Neoteny—the retention of childlike features into adulthood. These features trigger a protective, nurturing instinct and are universally seen as "cute" or "beautiful" in females.
The Heart Shape (Triangle)
Often considered the most feminine because it mimics the small jaw and wide eyes of a baby. It creates a delicate, doll-like appearance.
The Round Shape
High in soft tissue (cheeks), which signals youth and estrogen fertility. It lacks the "aggressive" angles of a square jaw.
Can a Square Face Be Feminine? ABSOLUTELY.
Think of Angelina Jolie or Margot Robbie. They have strong, square jaws (typically masculine traits), yet they are icons of femininity. Why?
This is the power of Contrast. A sharp jawline paired with large, luscious lips and eyes creates a "Femme Fatale" look—powerful yet alluring. It breaks the "cute" mold and moves into "striking" territory.
