Why do some people have dry hands and dark lines in winter?

1. Human factors: frequent contact with manual labor such as washing clothes and cooking will easily lead to dehydration, dryness and roughness of hand skin over time.

2. Weather factors: In relatively dry and cold weather, the elasticity of the skin will be greatly reduced, and the blood circulation speed in the body will also slow down. If you add frequent exposure, it is more likely to cause rough hands.

3. Physiological aging: With the increase of age, human metabolism will gradually slow down, with more and more dead cells and fewer new cells, which will easily lead to poor skin elasticity.

4. Metabolic disorder: Long-term stressful work or mental factors, as well as female fertility, may lead to metabolic disorder, which may lead to hand fractures.

5. Mold infection: Fungal infection can also cause rough palms. For example, keratinized and thickened sphagnum moss is characterized by cracked hands.

Preventive measures:

Choose mild cleaning products. In daily life, it is difficult for us to avoid contact with various cleaning products, such as facial cleanser, soap, soap, washing powder, detergent and so on. Excessive alkaline cleaning products will completely wash off the oil on the skin surface, making the hand skin dry and rough.

Don't wash your hands with hot water. Although it will be comfortable to wash your hands with high-temperature water for a while, it will only make your rough skin dry, because high-temperature water can easily cause a lot of water loss in your skin, destroy the balance of oil secretion in your hands, and make your skin dry and rough. So it's best to wash your hands with warm or cold water, not rough and dry hands.

3. Exfoliate once a week. One of the reasons for rough hands is that the keratin is too thick. You can soak your hands in warm water first, then gently massage your hands with scrub, and massage the back of your hand and palm 10 minutes. It is recommended to choose a scrub containing protein, because this scrub can effectively bleach and deeply clean the skin, remove dead skin and promote cell metabolism.

4. Bring hand cream. Apply soothing and repairing hand cream after each hand washing. After each bath, it is best to apply hand cream immediately when the stratum corneum still contains a lot of water. Carry hand cream with you during the day or at night and use it when you feel dry. It is recommended to choose a daily hand cream with SPF during the day.
