Why does dry skin itch?

Dry and itchy skin is related to sebum secretion. There are many factors that affect sebum secretion, including endocrine, age, sex, temperature, humidity, dietary physiological cycle, skin cleaning methods and so on.

Generally speaking, when the outside temperature and humidity are high in summer, sebum secretion is more, but when the weather is dry and cold in autumn and winter, sebum secretion is also reduced, so the skin becomes dry.

In addition, with the increase of age, the skin secretion function decreases, and the sebum secretion that protects and moisturizes the skin also decreases, which also causes dry skin itching, which is why the itching caused by dry skin is more common in middle-aged and elderly people.

In the dry season, skin moisturizing is also very important. Remember to apply moisturizing products to your skin in time after taking a shower. Moisturizing products can generally be divided into three dosage forms: milk, cream and oil. Milk and cream have a good moisturizing effect and are suitable for most types of skin. Oil has a good sealing effect, which can prevent water from losing through the epidermis, but it does not have moisturizing effect itself, and the skin feels bad when used alone.

In addition, it should be reminded that for people with sensitive skin, it is best to choose moisturizing products that do not contain alcohol, pigments and other irritating substances. It is best to choose wide and soft cotton or silk fabrics for personal clothes, and eat less spicy and stimulating food in the diet. For people with severe itching, which has even seriously affected their daily life and work, it is recommended to use some drugs under the guidance of a doctor, and do not use some topical antipruritic ointment at will to avoid secondary infection and allergy of the skin.
