Therefore, we should pay more attention to the health of the soles of the feet in normal times. Sometimes people will find a black spot in the skin on the soles of their feet. Why is this?

The production of melanin deposition[1] is mostly related to endocrine disorders and sunlight exposure. The number of melanocytes mainly depends on genetics. In addition, it is also related to endocrine hormones and nutritional status. Causes: Ultraviolet radiation: Ultraviolet radiation in sunlight is an important cause of pigmentation, which is why sun protection is needed in summer. When the skin is exposed to too much sunlight, the epidermis produces more melanin particles, which can absorb ultraviolet rays and protect the body from harm. This is why our skin becomes darker after sun exposure. Moreover, exposure to ultraviolet rays can cause chloasma, which darkens the color of common freckles.

Caused by endocrine disorders: Common ones include gynecological diseases. Long-term chronic diseases lead to weakening of vitality, and facial cells do not get the proper nourishment, which leads to the growth of pigmentation.

Strong ultraviolet radiation: There is a lot of UVA and UVB ultraviolet radiation in the air, which increases the free radicals in the skin, increases the activity of tyrosinase, produces a lot of melanin, and forms spots on the face that are difficult to fade.

Excessive stress: Long-term heavy life and excessive stress can lead to poor blood circulation and increased peroxidase, which can induce facial pigmentation.

Eating disorders: Long-term lack of vitamin A, B12, niacin and other substances in food causes yellow complexion and numerous spots, which are difficult to eradicate and easily recur.
