dry skin
Introduction
Introduction Dry skin refers to thickening and roughening of the skin due to seasonal changes, lack of water and anemia. In autumn and winter, the sebum and water secretion of the human body will gradually decrease, and the skin will become dry. It is called dry skin. Especially in middle-aged and elderly people, the surface of the skin will appear more rough due to the large amount of water, and they will often see their hands and feet. There will be chapped and itchy skin in the calf. If you can't stand the dry itching, you will continue to scratch itching, causing skin wounds, causing inflammation or pus.
Cause
Cause
Due to seasonal changes, lack of water and anemia, the skin becomes thicker and rougher. In the clinical skin water content test, the normal epidermal water content should be 25%, but today the urban women's skin moisture content has dropped to about 15%.
1. Age increase: It is one of the causes of dry skin. As the level of estrogen in the body decreases, the secretion of sebum decreases, and the ability of the skin to retain moisture decreases, making the skin more and more dry.
2. Climate change: Changes in the external climate can cause abnormal secretion of sebaceous glands and sweat glands, and the surface of the skin becomes rougher and the resistance is also weakened. After a long time, it may be habitually dry.
3, lack of sleep, fatigue, excessive weight loss and partial eclipse: lack of sleep, fatigue, excessive weight loss and partial eclipse, the body will suffer considerable damage, blood circulation will also deteriorate. When health is out of balance, the skin will be inactive and prone to dryness and roughness.
4, bathe with overheated water, use irritating soap or detergent: In addition, bath with overheated water, use irritating soap or detergent, or female endocrine changes, such as women's secretion of estrogen after menopause, etc. It can also cause dry skin. However, this is a short-term phenomenon that can be improved immediately.

Diagnosis
Differential diagnosis
Drying incentive 1: air conditioning
Although the autumn is over, the temperature when the sun is shining is not lower than in the summer. The cold air of the air conditioner will make the air in the room dry, and the external humidity is not as big as that in summer. A part of the skin will be taken away. If it is ignored, it will easily appear fine wrinkles.
Drying incentive 2: UV
As the weather is clear, the ultraviolet rays in the sun are not covered by thick clouds, and the trouble of finding the skin is also coming.
Dry incentive three: excessive bathing
In summer, the temperature is high, people like to take a bath or two a day, and some people even more.
After the climate change, the sweat and oil secreted by the skin will gradually decrease. The excessive number of baths will easily wash away the sebum mixed with the cuticle and sweat that is automatically shed, which reduces the protection of these substances on the skin, and the water inside the cells is more likely to evaporate. The skin appears dry.
Drying incentive four: summer skin care products
The skin care products used in summer emphasize the refreshing, but these skin care products are a bit "out of date" in the late summer and early autumn. The ability to moisturize and lock water is obviously not up to the requirements, so it is best to start using some moisturizing skin care products to reduce Loss of moisture.
