Why does dry skin itch?

The phenomenon of dry and itchy skin is related to the secretion of sebum. There are many factors that affect sebum secretion, including endocrine, age, gender, temperature, humidity, dietary cycle, skin cleansing methods, etc.

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

In addition, as age increases, the secretion function of the skin decreases, and the secretion of sebum that protects and moisturizes the skin also decreases, which can also cause dry and itchy skin. This is why there are more pruritus caused by dry skin. The reasons why it appears in middle-aged and elderly people.

In the season of dry skin, it is also very important to moisturize the skin. After taking a shower, remember to apply a layer of moisturizing product to your skin in time. Moisturizing products can generally be divided into three dosage forms: emulsion, cream, and oil. Emulsions and creams have better hydrating and moisturizing effects and are suitable for most types of skin. Oils have a better encapsulating effect and can prevent moisture from being lost through the epidermis. However, it does not have a hydrating effect by itself and does not feel good on the skin when used alone.

Another reminder is that for those with sensitive skin, it is best to use moisturizing products that do not contain alcohol, pigments and other irritating substances. It is best to choose loose, loose cotton or silk fabrics for your underwear, and eat less spicy food. For those with severe itching that has seriously affected daily life and work, it is recommended to use some drugs under the guidance of a doctor. Do not use some topical anti-itch ointments on your own to avoid secondary skin infections and allergies.
