Men have dark complexion but not black body

Darkening of the face is a liver problem. The liver is responsible for digesting and absorbing nutrients and other substances in the colon and reorganizing them into its own substances. It is a very important organ in the human body. In addition, many toxins such as endotoxins will enter the liver and cannot be eliminated. Over time, they will accumulate and manifest externally as yellow complexion.

It may also be caused by a poor blood circulation system. You need to pay attention and strengthen your exercise regularly.

It may also be that the sun protection and isolation work is not done well, remember to apply sunscreen when going out.

There are two main ways of melanin metabolism. One is that it is dissolved by acidic and alkaline hydrolases during the growth and development of the epidermis, and finally falls off with the thinning of the stratum corneum. Another way is that it is migrated to the dermis and swallowed by melanophages, then dissolved in the blood circulation and excreted from the kidneys.

The first one is a natural function of the human body, but the second metabolic method can easily cause the skin to turn yellow and black for people with abnormal liver function.

When the liver detoxifies, because the blood is flowing, it does not shut down the blood to do this work, but detoxifies while the blood is flowing. At the same time, other parts of the body will also produce metabolic substances in the normal operation.

Therefore, there are always some toxins in the blood, which can never be completely eliminated. It is only to maintain the normal operation of the human body, but accidents and increased body cleansing burdens such as staying up late, drinking, taking medicine, infection, etc. Otherwise, not only the liver's detoxification function will be damaged, but other internal organ cells will also accelerate aging, which greatly increases the toxin content in the blood.

These bio-macromolecule toxic substances will make the blood viscous, blood flow slow, and eventually stagnate in the body's capillaries and become "dead blood".

You may not know how small the capillaries are. If you look at them with an optical microscope, you can see a small blood cell just barely passing through. If only one is blocked, it's fine. But if there are too many blockages, it's like a traffic jam. Over time, the blockage will get bigger and bigger, affecting each other, and traffic will be paralyzed.
