Anatomy of the Nasal Bridge: Light Reflection vs. Shadow Lines
The human nose consists of the nasal bones, upper lateral cartilages, and greater alar cartilages. When light shines directly on the face, the center dorsal ridge reflects bright light while the lateral sidewalls fall into soft shadow. Amateurs make the mistake of drawing contour lines down the far outside edges of the nose, which actually makes the nose look wider.
To slim and define, you must draw your parallel contour lines closer together directly on top of the dorsal bridge, leaving only a thin 3-millimeter center strip. Using a cool-toned desaturated taupe mimics the natural shadow created by facial bone recession.
The Exclamation Point Highlight Trick
Never draw a continuous solid stripe of bright highlighter all the way down the bridge to the tip of your nose; this elongates the nose and can make the tip look drooping.
Instead, use the 'exclamation point' method: draw a thin, straight highlight line down the upper two-thirds of the bridge, stop before reaching the tip, and place a tiny, bright dot on the very upturned tip of the nose. This creates an immediate button-nose lifting effect.
