The aging process of the face

If we want to know the signs of aging, then the skin is the most obvious one. As we age, our skin condition changes all the time, and the most obvious sign of aging is wrinkles. Therefore, many women pay great attention to facial care when delaying aging. So, what is the facial aging process like? After understanding, we can better delay aging.

An activity that occurs and develops during life, and is a process of loss and degeneration of the body's constituent materials, organizational structure, and physiological functions. The aging process occurs continuously from the fertilized egg to death, and the characteristics of aging only become more obvious at a certain stage. The physiological changes during human aging are mainly reflected in the loss of tissue cells and constituent substances, the slowdown of the body's metabolic rate, and the decline of body and organ functions. Aging is inevitable, but delaying aging is possible. A reasonable diet and balanced nutrition are one of the important measures to delay aging and prolong life.

The main physiological manifestations of aging are:

(1) Morphological changes. Includes: ① Cell changes. The main manifestation is a gradual decrease in cell number. ②Changes in tissues and organs. As the number of cells in internal organs and tissues decreases, they atrophy and lose weight. ③Overall changes. As we age, our body shape and appearance change, such as graying hair; reduced skin elasticity, wrinkles, and age spots; loosening and falling teeth; deafness, blurred vision, hunchbacks, and a gradual decrease in height.

(2) Decreased physiological functions. Including: ① Decline of cardiovascular system function. For example, myocardial fibers gradually atrophy, senile pigments (lipofuscin) are deposited in myocardial cells, and heart valves become hypertrophic and hardened, with reduced elasticity. ②Aging of respiratory organs. It manifests as reduced lung capacity, significantly decreased respiratory function, and reduced compensatory ability. ③Changes in the digestive system. The main symptoms are weakening of oral and gastrointestinal functions, and atrophic changes in gums and teeth. ④Changes in the musculoskeletal system. It is mainly manifested in that with age, muscle fibers become thinner, their elasticity decreases, and their contraction force weakens; the organic components in the bones decrease, and the inorganic salts increase, which causes the elasticity and toughness of the bones to decrease, making them more susceptible to fractures. ⑤Changes in the nervous system. The main manifestations are a certain degree of loss of brain cells; decreased nerve conduction velocity; slow movements and reduced reflexes in the elderly.

(3) Decreased function of major sensory organs. Such as decreased vision, hearing, smell, taste, and skin sensation (including touch, temperature, and pain). In addition, the psychomotor responses of the elderly are also correspondingly slow.
