When the temperature is cold, the skin of hands will become very black. What's going on here?

When the temperature is cold, the skin of hands will become very black, because the cold temperature will slow down the blood circulation. When we are exposed to cold environment, blood vessels will contract, thus reducing the blood supply to the skin. Because blood contains a lot of oxygen, if the skin lacks enough oxygen supply, it will lead to dark skin color. Cold weather will also squeeze and bind tiny blood vessels on the skin surface, making the skin look paler.

Low temperature environment may also lead to the increase of stratum corneum thickness. The stratum corneum is the outermost protective layer of the skin, which is composed of dead keratinocytes. Cold weather will stimulate the skin to produce more keratinocytes and protect the skin from external damage. This can easily cause the cuticle on the skin surface to be too thick, which blocks the healthy and transparent color of the dermis and makes the skin look darker.

In order to avoid hand skin blackening in cold weather, we can take some protective measures. Pay attention to keep warm, wear suitable gloves or warm clothes to prevent the influence of low temperature on the skin. To maintain good blood circulation, you can promote blood flow by rubbing your fingers and hands frequently. It is also important to use moisturizing cream or moisturizing products in time. Moisturizing hand cream is a very popular product, which can provide enough moisture and moisture for the skin and effectively prevent dryness and blackening.

In cold weather, the blackening of hand skin is caused by slow blood circulation and thickening of cuticle. In order to keep hand skin healthy and bright, we can take some measures, such as wearing warm products, promoting blood circulation and using moisturizing cream. I recommend Feng Run Hand Cream, which has a good reputation and effect, and the price is affordable. I hope the above suggestions can help you keep your hands healthy and beautiful in cold weather.
