What happened to my hand? It's a bit like the color of congestion. I haven't been hurt, I haven't used drugs indiscriminately, and it doesn't hurt or itch, but my little finger is swollen. Now I'm outside, frozen stiff. This is because the skin has cracked in winter.

When the weather turns cold in winter, the humidity in the air decreases, or the use of heating can lead to chapped hands and skin.

The main reason of drying cracking is water shortage; Then cold reduces the elasticity and activity of hand skin and reduces secretion; Another reason is the lack of vitamin B family, which leads to dryness. Especially around the nail bed, because the nail itself belongs to water-deficient tissue, the edge of the nail bed is prone to dryness.
