Why is my face and body dry and dandruff when it comes to winter?

The main reasons of skin desquamation and desquamation are that the skin is dry and dehydrated in winter, and the skin loses its water-locking function, which leads to the damage of the stratum corneum, the Min Min of the skin to external stimuli increases, and the skin will fall off to form dandruff! Clean skin care products, the purpose of which is to use surfactants to remove dirt attached to the face or body! Moisturizing is the most basic function of skin care products. Dry skin lacks water, that is, fine lines and desquamation appear. Replenish moisture for the skin and lock moisture first, so as to effectively alleviate the problem of dry skin!

Replenishing water is to replenish water to the skin, and moisturizing is to lock water in the skin! Simply hydrating the skin, the replenished water will be lost quickly, so moisturizing products are needed to form a protective film on the skin surface to reduce water evaporation and lock water! Water-oil balance is one of the signs of skin health, but the water-oil ratio of each person's skin is different, so you should take corresponding skin care methods according to your skin condition! While hydrating and moisturizing, be careful not to go astray, otherwise the result may be counterproductive!

The sebum level of oily skin is closely related to congenital factors. If you don't pay attention to the diet after tomorrow, the sebum problem will be aggravated! Hydrating products are essential skin care products for many people, but there are still more skin water shortages, which will cause various skin problems. One of the main reasons for water shortage is that the skin can't lock in moisture, that is, the skin barrier sebum membrane is damaged! When the sebum membrane is damaged, we can only replenish water, but can't lock the water well, so the water will be lost quickly, and the response to climate and other factors will be weakened, which will easily cause redness, local redness and even sensitivity! Nowadays, more and more skin care products are mainly based on repair. When the water-locking barrier is intact, hydration and water-locking can be carried out at the same time to protect skin moisture!

What does the skin need?

The six functions of skin are to protect, feel external stimuli, regulate body temperature, excrete, secrete and absorb nutrients. What is needed is to be able to play these functions normally! The protective function of skin mainly depends on sebaceous glands, sweat glands and stratum corneum. By secreting water and oil, the water content on the skin surface is guaranteed to be 10%-20%. Below 10%, the stratum corneum will crack, and above 20%, the defense ability of stratum corneum will decrease, and there is an upper limit for hydration!

Let the stratum corneum work normally, thin skin will reduce the action that leads to less stratum corneum, and the stratum corneum thickness needs to be moderate! Let sebaceous glands work normally, that is, produce moderate oil without increasing the oil content. If the oil is reduced, use the product to supplement it! Let the sweat glands work normally, and the air-conditioned room can stay for a while and exercise properly!

External application can't replenish water to the deep skin (dermis). The so-called beauty after hydration is due to the instantaneous increase of water content in the stratum corneum! What is more important than hydrating is to lock water, and to say less about water loss is moisturizing ability! The factors causing dry skin are weather, environment, skin care methods, age, low skin lipid content and so on. , leading to the decline of skin barrier ability and the gradual loss of the ability to prevent water evaporation. The supply of water can't keep up with the loss, leading to dryness!

The moisture of the skin is always in the process of evaporation, which is a natural process of the human body, which is equivalent to completely hydrating and moisturizing the skin from the inside out! As long as the evaporation rate and fresh water supplement are balanced, it is completely ok. Proper exercise is to increase the function and metabolism of body organs, which will directly increase non-inductive evaporation!
