The superciliary arches – in other words, the ridge or bossing of bone above the eyebrows – is a classic feature in biological males. This characteristic masculinises female faces, giving them a hardened expression and appearance. So facial feminising likewise includes the reduction of these arches.
To modify the brow, the frontal sinus is filed down and/or remodelled to soften its prominence. In the same operation, the hairline may also be lowered. This helps to attain a more feminine forehead, while the eye features are likewise improved.
We should bear in mind that the female face is more oval while the male’s is squarer. So it is often also necessary to change these features by modifying the jawline and chin through facial feminisation surgery.
