Why is autumn so dry?

Generally speaking, it can be said that autumn and winter are the most prone to skin problems in a year, and most of the problems are related to dry and sensitive skin, which makes many women very upset. Why does the skin become particularly dry and sensitive?

Let's analyze the physiological changes of skin: in addition to protection and feeling, the most important function of skin is to regulate body temperature, and secondly, excretion and secretion are also very important. Whenever the climate gets hot or the humidity increases, the metabolism of the body will also increase. At this time, in order to maintain a proper body temperature and excrete a large number of metabolites, the function of sweat glands is of course maintained at a relatively strong level. At this time, the pores open, sweat glands open, sebaceous glands secrete more, sweat excretion also increases, so that excess heat and metabolites are excreted.

However, when the climate turns cold, in order to reduce energy consumption, the metabolism of the human body is also reduced, the pores are closed, and the excretion of sweat glands and sebaceous glands is reduced. With the decrease of these secretions and excretions, the oil content on the skin surface also decreases. If your skin is dry or older, it is more likely to cause dry skin and dry sensitive skin with water shortage in the stratum corneum.

For dry skin, the secret of maintenance is: drink more water, less irritation, moisturize frequently, use nutritious and moisturizing skin care products, avoid too hot water and irritating facial cleanser, and prevent the moisturizing layer on the skin from being washed away.
