What are the common causes of white spot skin diseases

White spots appear on the skin and tend to expand. Generally speaking, this is vitiligo. We know that vitiligo is a relatively stubborn skin disease. There are many causes of vitiligo. First of all, vitiligo is related to genetics and improper living habits. For example, poor diet and lack of trace elements in the body can lead to melanin metabolism disorders. In addition, bad emotions can also lead to endocrine disorders. Frequent exposure to the sun can easily induce melanin formation disorders.

1. Diet and vitiligo:

Relevant studies have confirmed that when the human body lacks trace elements such as copper, zinc and iron, the activity of tyrosinase can be reduced, affecting melanin metabolism disorders. Therefore, the lack of certain trace elements in the body of vitiligo patients leads to melanin metabolism disorders. Therefore, patients with vitiligo should eat more foods rich in tyrosine and minerals, such as meat, eggs, pork liver, peanuts, walnuts, black sesame and other nuts.

2. Emotions and vitiligo:

Good or bad emotions bring different results to the disease. Most vitiligo patients are depressed, pessimistic, disappointed and worried. Some people are afraid that the disease will progress and affect their facial appearance, and they become disgusted with life and commit suicide. Tension affects the formation of melanin because tension stimulates the secretion of adrenaline, and the synthesis of adrenaline also requires tyrosine. A large loss of tyrosine will inevitably affect the synthesis of melanin, which is not conducive to the treatment of vitiligo. In order to cure the disease, the sick person should be optimistic, stabilize his emotions, feel happy, and eliminate negative factors such as impatience and fear. Actively cooperate with the doctor's treatment.

3. Sun exposure and vitiligo:

As we all know, the depth of human skin color, black and white are often affected by seasonal changes. Summer sun exposure and sunbathing after swimming will cause the skin color to darken. People may ask, how does sun exposure darken the skin? Scientific research suggests that sunlight contains ultraviolet rays, which can stimulate the activity of enzymes in the human body's melanin metabolism process, accelerate the conversion of tyrosine into dopa and dopaquinone, and promote the formation of melanin. At the same time, ultraviolet rays can inhibit and interfere with sulfur-based substances in the skin, inhibiting the activity of tyrosinase.
