winter is the time when the skin is easy to dry. Many girls are prone to skin problems at this time. Dehydration and dryness of the skin are normal. The following is some common sense about skin dehydration.
what is a lack of water on the skin?
skin itself has a complete moisturizing system, which can maintain the normal moisture content of the skin, but it is damaged by us intentionally or unintentionally; to put it simply, the stratum corneum is dehydrated. When the water content of the stratum corneum is less than 10%, it will lead to dry, tight, rough skin with abnormal cutin metabolism, abnormal shedding of fish cells (peeling) and so on. The harm of
 
skin dehydration: the activity of

1. surface cells is decreased, collagen is lost, the skin loses elasticity,
2. appears fine lines and plain lines
3. pores are thick, the skin is rough,
4. skin is sensitive, fragile

 
skin is lack of water,

1. skin is too tight. Skin tightness is caused by long-term dehydration or intermittent dehydration. The lack of water and nutrients in the skin can easily lead to no elasticity, no touch, no sealed
2. skin lines. When the skin is severely dehydrated, the fine lines will evolve into long and deep dry lines that can be clearly seen even without powder. The wrinkles on the forehead and the corners of the eyes are looming, and the facial skin is often red and
3. skin is sensitive. Long-term lack of water will cause the loss of skin barrier function. Greatly reduced, easy to cause skin sensitivity, that is, general barrier damage.
4. skin peeling and peeling. Peeling and peeling is a symptom of severe skin dehydration. Dehydration of the skin leads to desquamation because the stratum corneum on the face dries and falls off, resulting in dead skin or dandruff
5. pores are thick. The lack of water in the skin leads to the abnormal metabolism of keratin on the face. Too much keratin accumulates in the hair follicles and sebaceous glands, which makes the skin rough. Rough skin can easily lead to blockage of pores and coarse pores.

1. age: with the growth of age, skin aging, nutrient loss, skin moisturizing and barrier function weakens
2. damage to the stratum corneum: excessive exfoliation, dermatitis, acne, etc., wash off a large amount of oil from the face, take away the natural moisturizing factors in the stratum corneum, will cause damage to the stratum corneum, easy to dry and peel off. The water intake of
3. is too little: rehydration of stratum corneum. The main source is the dermis, the moisture in the dermis comes from our daily diet and directly replenishes the
4. weather and seasons: alternating seasons, cold and dry climate, low temperature
5. environment: reduced air humidity, dry air, moisture in the skin is more likely to evaporate into the air, such as long-term air-conditioning environment, computer TV radiation The skin is easy to dry

Q: the more water, the drier the skin?
answer: the lack of water caused by the damaged skin barrier, the skin does not have the ability to lock water, the water will quickly evaporate and return to dry state, so it is mainly to repair the barrier at this time.
asked: do you always moisturize as long as your skin is dry?
: if the hydration is too diligent, it is easy to cause excessive hydration and softening of the stratum corneum, making the skin more vulnerable to external damage, resulting in further damage to the stratum corneum and a decline in moisturizing ability after the use of skin care products.
asked: does skin tingling mean lack of water?
: no, tingling occurs only when the skin is extremely dehydrated and dry, but in most cases, it may be because your skin is intolerant of a certain product ingredient, or your skin barrier is damaged
Q: does the skin need to be hydrated?
: it’s not necessary! When your skin is dehydrated, you must understand the causes of your skin dehydration. For example, your skin is dehydrated because the skin barrier is damaged, but if you hydrate the skin in a fragrant way, it will make the skin barrier more damaged.
