What are the internal reasons for dark skin?

The reason why the skin is dark mainly depends on the ability of melanocytes to synthesize melanin. Melanocytes are distributed between the basal cells of the human epidermis. The tyrosinase they contain can oxidize tyrosine into polysaccharides, which then go through a series of metabolic processes to finally produce melanin. The more melanin is produced, the darker the skin will be; conversely, the whiter the skin will be. The specific reasons are:

1. Sleep and mental state: Staying up late often will cause loose skin, dark circles and spots. Long-term mental stress, depression and other negative emotions can also make the skin dull and cause spots.

2. Endocrine factors: pregnancy, irregular menstruation, etc. can increase the synthesis of melanin in the epidermis, leading to pigmentation.

3. Chronic diseases: Chronic infections, tumors, liver and kidney diseases and other chronic diseases can cause changes in skin pigmentation. The liver is the body's metabolic organ, and metabolic products must be excreted through the kidneys. Once the liver or kidneys malfunction, it will affect the metabolism of the whole body. If toxins cannot be excreted in time, the skin will become dull and lifeless.

4. Drug factors: Long-term use of certain antibiotics, painkillers, arsenic-containing preparations or contact with tar substances can cause skin pigmentation changes.

5. Poor diet: Bad eating habits can cause skin pigmentation. If some people do not like to eat vegetables, over time, their bodies will lack vitamins and their skin will be prone to pigmentation. Some people will turn their skin yellow if they eat 1 kilogram of oranges in a day.
