The epidermal cells of the skin are constantly metabolized to maintain the integrity, defense and excretion of the skin. Its luster, elasticity and compactness are influenced by many factors. Such as hormone secretion level, skeletal muscle tension, nutrient digestion and absorption, neurological factors and so on. The reasons for the general sagging of the skin of the elderly are as follows.
1. Decreased levels of endocrine hormones in the elderly: for example, decreased secretion of estrogen, androgen, growth hormone and cortical hormone, the impact on the skin is decreased elasticity, relaxation and dullness.
2. The elderly have low exercise, and the arterial blood flow to the muscles decreases, leading to muscle atrophy. This condition is called "disuse atrophy" or "physiological atrophy" in medicine. Skin and subcutaneous tissue lose the strong support of muscles, and naturally there will be relaxation and sagging.
3. The digestive absorption function of the digestive tract of the elderly is reduced: the absorption capacity of nutrients is reduced, especially the absorption of collagen and vitamins is significantly reduced, which makes the skin slack and droopy.
Elderly people with drooping skin don't need cosmetic intervention. Deep wrinkles and rough face are the vicissitudes of time and the accumulation of life. Let's respect and care for the elderly together.
Young people have full skin and strong bones and muscles, while old people are wrinkled and weak. Skin is also one of the organs of the human body. With the increase of age, subcutaneous muscle and adipose tissue will change, and even the skeletal system will shrink, leading to the increase of wrinkles in the elderly.
At least for modern people, aging is inevitable. ① Skeletal muscle atrophy: The tissues and organs of the elderly have accumulated a lot of injuries because they have been running all their lives, so the functions of many organs and tissues have slowed down or even failed. The weakening of gastrointestinal function makes it difficult for the elderly to enjoy the hard food rich in protein, and the intake of nutrients is not as fast and effective as that of young people. Therefore, the change of bone properties leads to the loss of bone materials, and bones become more fragile and fragile. The bone marrow of long bones is also yellow bone marrow, that is, tissues with high fat content and insufficient hematopoietic capacity. The length of long bones will be shortened, and the thickness and shape of flat bones and irregular bones such as vertebrae will change, so the head of the elderly will gradually become smaller, and accordingly muscles will gradually lose because of lack of nutrition, and muscle strength will decline;
(2) Substances and energy stored in the body: Young and middle-aged people are engaged in greater work intensity and more physical activities than the elderly, so the body needs to store more substances and energy to cope with the ever-changing life, so the bones and muscles are stronger, and substances such as fat are also stored under the skin and stomach, so young and middle-aged people have better durability in work and life and stronger tolerance to food shortage than the elderly. Sufficient physical storage of matter and energy is also more conducive to young adults to resist the invasion of pathogens or other pathogenic factors and make them less sick.
(3) Organ dysfunction: The regeneration ability of human muscle and nerve tissue is very poor, and it has been lost since birth. However, due to physiological compensation, physical strength will not weaken in the process of growth, but will increase. However, in old age, because of living longer, organ and tissue consumption is more serious, and heart weakness makes it difficult for the elderly to work for a long time. The weakness of the kidney leads to frequent urination in the elderly, because the ability of the kidney to reabsorb the water in the original urine decreases. The longer you live, the more serious your relative organ function will be lost. Therefore, the strength of bones and muscles of the elderly will decrease, and the pressure on organs to excrete metabolic waste will be greater. Therefore, the elderly usually have some visceral problems, and senile diseases usually coexist, unlike the diseases of organs and tissues in young adults, which are usually more limited.
Changes of bones, muscles, subcutaneous fat, etc. Make the elderly more wrinkled. Similarly, if obese people lose weight successfully, their skin, which has been stretched by a lot of subcutaneous fat, will collapse and sag without the support of fat and other substances, and many obvious wrinkles will appear, so it is necessary to remove excess skin tissue through plastic surgery.
Because with the growth of age, people's skin will gradually relax and sag because of the gravity of the earth. We can often pat our face to make it firmer. Time has taken away the face of youth, but we can maintain a good attitude, which is the best nourishment for body and mind.
When people reach old age, due to the aging of organs and systems, the function of new diarrhea declines, leading to the decline of circulation, endocrine and other functions, leading to the weakening of somatic cell regeneration ability. This makes the absorption capacity of human nutrition decline, and nutrition is lacking.
The above reasons make the hungry meat and fat of the elderly shrink, while the original skin will sag. thank you
1. With the passage of collagen, the skin's water-locking ability decreases. 2. Damage caused by sunlight and ultraviolet rays leads to skin aging and water loss. 3. The gravity of the earth will also lead to sagging skin.
Why does the old man's skin droop?
When people get old, they can't escape the problems of aging and atrophy of skin, deepening facial wrinkles and drooping eyelids.
Once a person enters old age, the skin will gradually age like other organs of the body. In addition to dry skin, deepened facial wrinkles, drooping eyelids, there will be pigmentation, hair thinning and whitening, which is an inevitable physiological law.
Why are young people full of skin and strong bones and muscles? Old people are wrinkled and weak? That's because skin is also one of the organs of the human body. With the increase of age, subcutaneous muscle and adipose tissue will change, and even the skeletal system will shrink, leading to the increase of wrinkles in the elderly.

With the growth of age, people's skin will become rough and loose, with large pores and skin color will also change. This change will occur because: 1. Air oxidation. 2. Free radical erosion, 3. Atmospheric environmental pollution. Gravity leads to relaxation. 5. The human body secretes itself vigorously. 6. UV damage. Relief and prevention: Just like the grease on leather glows, human skin also needs care to keep it in a state of water-oil balance. Don't deliberately pursue what kind of effect, keep a healthy attitude and insist on using mild, colorless and non-irritating skin care products. Cleaning and moisturizing are the most basic tasks of skin care. Combined with your specific skin problems and care needs, use some targeted products at night when the skin absorption is at its best. Eyes and neck are the most delicate and prone to aging, so take good care of them. Skin care should basically do these things: cleaning, moisturizing, moisturizing, exfoliating and firming nutrition (mask)
Because of the loss and aging of muscles, subcutaneous fat, water and cells, they lose their elasticity and can't take care of thick skin tissue, and fall down because of the attraction of gravity.
As we all know, the skin of growing children is smooth, delicate and shiny, and there is no need for skin-related care at all, because the number of cell regeneration in the human body during this period is far greater than the number of aging and death every day. With the increase of age, people will have a series of problems, such as skin aging, wrinkles and spots, decreased skin elasticity, increased skin relaxation and decreased overall mental vitality. The fundamental reason is that the number of cells born every day in the human body is far less than the number of cells that die every day, that is, the level of cell metabolism is far less than that of children.
The reason why the human body is aging is mainly because the speed of cell renewal is less than that of aging, and there is not enough fresh cells. As important signs of aging, cell senescence and stem cell depletion are important factors driving the occurrence and development of senile diseases.
