Four numbers separate a masculine face from a feminised one, and every one of them is easy to overshoot in surgery. We aim deliberately short of the target.
The angle between the upper lip and the base of the nose is the single measurement that decides whether a male nose reads as male. In men it sits around ninety to ninety-five degrees; in women a hundred to a hundred and five is considered attractive. Rotating a man's tip up to a number that looks good on a female patient feminises the whole face, and no amount of dorsal work compensates for it afterwards.
A male brow is straight, relatively low, and sits at or just below the bony orbital rim. A female brow arches and sits above it. Lifting a man's brow — surgically, or with too many units of botulinum in the wrong place — produces the permanently surprised look that reads instantly as work done. In male patients we treat the frown complex and the crow's feet, and stay deliberately conservative on the forehead to keep the brow down.
Most men who ask for a jaw implant have a full submental fat pad blunting the angle between chin and neck. That angle should be roughly ninety to a hundred and five degrees; when fat fills it, a strong jaw disappears regardless of the bone underneath. Liposuction of the neck, sometimes with a small platysma tightening, restores the line for less money, less risk and no foreign material. Implants are for genuinely deficient bone, which is a minority.
With men we deliberately aim slightly short of the target and review at twelve months. Undercorrection is invisible; overcorrection is the thing people notice, and reversing it means a second operation with worse odds. This is also why we decline requests that fight the rest of a face: a very upturned tip, a high arched brow, cheek filler placed as it would be on a woman. Saying no is part of what you are paying for.
Male skin is thicker and more vascular, so bruising is often heavier and swelling lasts a little longer — particularly in the nose, where thick skin delays tip definition by several months.
Sometimes the honest answer is no. A large change to a defining feature will be noticed. What we control is whether it looks like a different nose or like surgery, and that is a question of proportion rather than size.
