Face is feasibly susceptible to aging.

Face is considered the most aging-sensitive biometric trait. While it’s affected by the natural process of growth, it’s also influenced by the climate conditions, health habits, gastronomic preferences, lifestyle, stress, and so on.

Other traits are less affected by aging. For example, human fingerprints stay permanent for the entirety of life with a few minor changes that cannot thwart biometric recognition.
