Add a bright red smile that’s a little bigger than your lips. Activate the red paint and grab a fresh cotton ball or cotton pad. Dip the ball or pad into the red paint and carefully add the iconic smile. Cover your lips and extend the smile 1–2 inches (2.5–5.1 cm) past the edges of your lips. Curve the line upwards on each cheek to give yourself the Joker’s famous smile.
