skin aging
Introduction
Introduction Skin aging is a phenomenon of skin aging caused by natural or unnatural factors. After birth, the skin tissue is increasingly developed, and its function is gradually active. When it reaches a certain age, it will begin to degenerate. This kind of degradation often takes place slowly and unconsciously. The growth period of skin tissue generally ends at around 25 years old. Some people call this period the "corner angle of the skin". Since then, growth and aging have been carried out at the same time. The skin elastic fiber is gradually thickening, and the age of 40-50 years old is slow. Slowness is obvious, but the degree of aging varies from person to person.
Cause
Cause
Skin aging is caused by many factors, and there are nine aspects in summary:
1. Age factor. Skin aging generally begins around the age of 30. This is the only unavoidable factor and the rest can be changed.
2. Health factors. When suffering from chronic wasting diseases such as kidney disease, liver disease, and gynecological diseases, the skin is prone to aging.
3. Mental factors. Excessive brain use, excessive thinking, and troubled skin are prone to aging.
4. Nutritional factors. The skin is prone to aging due to poor chewing and gastrointestinal dysfunction, malnutrition, or lack of protein and various vitamins in the diet.
5. Living habits. Staying up late, fatigue and smoking can accelerate skin aging.
6. Environmental factors. Long-term sun exposure, wind and rain, or seawater erosion, the skin is prone to aging.
7. Endocrine disorders. After menopause, the secretion of estrogen is reduced, which affects the skin's fullness and elasticity.
8. Improper skin care.
9. Improper medication. Improper use of medications or cosmetics can cause skin aging.

Skin aging is mainly manifested in two aspects:
1. Skin tissue decline: The thickness of the skin changes significantly with age. The human epidermis is the thickest at the age of 20, and then gradually thins. When the old age, the granular layer can shrink to disappear, and the survival time of the spine cells is shortened. Epidermal cell nuclear fission increases, so melanin also increases, so that the skin color of the elderly is mostly brownish black. As the aged cells adhere to the stratum corneum of the epidermis, the surface of the skin becomes hard and loses its luster. The dermis is thickest at the age of 30, and then gradually thins and shrinks. Subcutaneous fat is reduced, and the skin elasticity and tension are gradually lost due to changes in elastic fibers and collagen fibers, which further leads to skin sagging and wrinkles.
2. Low physiological function: The function of sebaceous glands and sweat glands is declining, the elimination of sweat and sebum is reduced, and the skin gradually loses its former luster and becomes dry. The blood circulation function is reduced to supplement the necessary nutrients of the skin, so the skin wounds of the elderly are difficult to heal.
Diagnosis
Differential diagnosis
Skin crease: dermatolysis, also known as cutis laxa, or generalized elastolysis, a skin sagging disease caused by congenital defects in skin elastic fibers And can invade the whole body connective tissue, involving the normal structure and function of cardiovascular, respiratory, urinary and other organs. Usually divided into two types: innate and acquired.
A large amount of skin desquamation: normal human skin is constantly undergoing daily metabolism, especially when the surface is constantly renewed, keratinized, and some dead skin is produced, which will cause skin desquamation, but this physiological phenomenon is generally small. There will be feelings. If there is a lot of skin desquamation in the skin, it should be considered as a manifestation of the disease. The skin looks dull, dry, scaly, rough and uneven to touch, often accompanied by itching, peeling, chapping and other symptoms, and even the formation of wrinkles, spots and so on.
Poor skin elasticity: The skin is the largest organ in the human body. The total weight accounts for 5% to 15% of the body weight. The total area is 1.5 to 2 square meters. The thickness varies from person to person and from 0.5 to 4 mm. The skin covers the whole body, and it protects various tissues and organs in the body from physical, mechanical, chemical and pathogenic microorganisms. The skin has two barriers: on the one hand, it prevents the loss of water, electrolytes and other substances in the body; on the other hand, it prevents the intrusion of harmful substances from the outside. Maintaining the stability of the human body's environment, it plays an important protective role in the physiological, and the skin also participates in the metabolic process of the human body. There are several colors of skin (white, yellow, red, brown, black, etc.), which vary mainly depending on race, age and location. Poor skin elasticity is a skin problem such as cell elastic atrophy and skin accelerated aging.
Yellowing of the skin: pigmentation of the skin, resulting in yellowing of the skin. Skin yellow has its roots. Some are caused by bad habits, and some may be organic. According to clinical studies, 80% of skin problems are associated with liver, spleen, and kidney dysfunction. Such as: liver directly affects the blood, liver anger or liver qi stagnation is easy to form qi and blood, affecting the blood circulation of the face, the skin is naturally dull; spleen digestion, absorption, if the spleen, absorption of nutrients in food and conversion energy will be affected influences. Yellowing of the skin and long spots will follow; ancient medicine says "kidney black" means that kidney deficiency can cause black and yellow skin. Therefore, you should diagnose the endocrine according to your own cause after diagnosis, which is the key to improving the skin.
