What is the physiological mechanism of skin aging?

Skin is an important part of the human body and, like other organs, it will gradually age. It is normal for the skin to age, and when the skin ages, it has a huge impact on the body's image. What causes skin aging? What is the physiological mechanism of skin aging? Let’s take a look at the introduction of this article below, hoping it will be of some help to you.

Causes of aging skin:

Internal causes:

a. Natural decline in the function of skin appendages

Due to the reduced function of the skin's sweat glands and sebaceous glands and decreased secretion, the skin becomes dry due to lack of moisture, causing more wrinkles.

b. Nutritional disorders of the skin

The skin on the face is thinner than the skin on other parts of the body. Due to nutritional disorders of the skin, subcutaneous fat storage gradually decreases, cells and fibrous tissues are malnourished, and their performance decreases, causing wrinkles on the skin.

External factors:

1) Frowning all day long, worrying about nothing

This will cause skin cells to lack nutrition, the skin on the face to become dry and dull, wrinkles to appear, and will also deepen the "worry lines" on the face. A smile makes you ten years younger. Emotional stability is very important for endocrine balance. A woman with a gentle and tolerant heart is very beautiful. In fact, it is not just a psychological impression.

2) Staying up late

Staying up late is the enemy of skin care. Lack of sleep will cause various regulatory activities of skin cells to become abnormal and affect the vitality of epidermal cells. So you should sleep at least 8 hours a day. If you sleep less than this, you should re-estimate your health index. Whether you get enough sleep can be easily reflected in your skin, especially the delicate skin around your eyes. A good and sweet sleep can eliminate skin fatigue, restore the regulatory activities of skin cells to normal, and delay skin aging.

3) Frequent exposure to the sun

Absorbing too much ultraviolet rays has many disadvantages. At the very least, it will make the skin darker and rougher. At worst, it can cause skin cancer. It is of course one of the culprits of premature skin aging. Because direct sunlight can directly damage the elastic fibers and collagen deep in the skin, causing the facial skin to become loose and dull, and wrinkles to appear. Therefore, develop the good habit of using high-quality sunscreen.

4) Smoking and drinking

Nicotine has a constricting effect on the blood vessels in the skin, so wrinkles appear on smokers' skin 10 years earlier than on non-smokers. Therefore, if you are a smoker, you will look 10 years older than your peers. Drinking alcohol will reduce the amount of oil in the skin, causing skin dehydration, and indirectly affect the normal function of the skin.

5) Excessive facial expressions

Frequent squinting, frowning, laughing wildly, and pouting, these actions and expressions will add wrinkles to the face, so it is best to minimize facial movements and excessive expressions.

6) Don’t like to drink water

Water is the source of life. The key to skin care is to replenish the skin with sufficient moisture in time. If you don't drink enough water, it will lead to insufficient oil secretion and your skin will easily become dehydrated, so you must force yourself to drink 6 to 8 glasses of water every day, but don't drink caffeinated beverages.

The above is an introduction to the physiological mechanism of skin aging. Skin is an important indicator of a person's age. When the skin ages, it has a great impact on a person's psychology. Therefore, knowing more about the causes of skin aging and taking preventive measures in life will be very helpful in delaying skin aging and should be paid attention to.
