    Facial recognition uses a few key elements of the face to hone in on matches, and traditional makeup doesn’t obscure any of those areas. In order to fool facial recognition, the goal is often to avoid face detection in the first place; Asymmetry, large contrasting colors, obscuring one (or both) eyes, hiding the oval head shape and jawline, and rhinestones (which sparkle and reflect light nearly randomly, making videos more confusing) seem to work well. But as neural nets improve, they also get harder to fool, so what works for one system may not work for every system.

    CV Dazzle (originally inspired by dazzle camouflage used on some warships) is a makeup style that tries to fool the most popular facial recognition systems.

    Note that those tend to obscure the bridge of the nose, the brow line, the jawline, etc… Because those are key identification areas for facial recognition.
