Patient's question:
Thank you for the doctor's quick answer for me - how to treat and preventDoctor's answer:
Vitiligo can occur on any normal skin on our body. It is often discovered as sudden, irregular-shaped patches of depigmentation on the skin, and sometimes the hair in the affected area may also turn white. In the summer, when the white patches of vitiligo are exposed to sunlight, they often turn red or cause a burning sensation. This is mainly due to the lack of melanin protection in that area. The synthesis of melanin cannot occur without tyrosine and tyrosinase; if either is missing, melanin cannot be synthesized, and the skin tone will turn white. Tyrosine is obtained from food through digestion and absorption, while tyrosinase, although synthesized in the human body, its activity is related to certain metal elements such as copper, zinc, and iron. When the body lacks these elements, the activity of tyrosinase is reduced, which affects the metabolism of melanin and leads to lesions.
