The face is indeed a very special part of the aging process. For example, we may meet well-proportioned women at ordinary times, but their faces show signs of years prematurely, while some elderly women have incredible young faces.
In a person's life, the face will experience three distinct and unrelated forms of aging: first, of course, it is "physiological aging", followed by "external environment aging", and everyone will also cause "internal environment aging" because of different life experiences.
Physiological aging is systematic, and the external environment aging is related to everyone's lifestyle, while the so-called "internal environment aging" is purely from psychological factors and is a subjective evolution. The shape of the face is reshaped to adapt to specific feelings, which is completely different from person to person.
