Vitiligo is a medical condition in which skin starts to lose its pigment, and lighter pigmented patches start to appear all over the body. It a long term skin condition, and these are the characteristic of this condition. How fast vitiligo can spread is unpredicted, and it can appear at any part of the body. It can even affect the hair growing from the affected spot, and they can also lose their color.
The healthy pigment of human skin depends on the melanin count, and in the case when the melanin starts to die, or their function becomes slow, it can trigger vitiligo. So what is melanin? Melanin is a pigment of the skin, and the color of skin, hair, and eyes are depending on it.
Studies show that melanin helps skin to protect from harmful UV rays. Also, studies show that people with darker skin have a low chance of having skin cancer. It is because an increase in the count of melanin can reduce and block the processes that can lead to skin cancer. In the case of vitiligo, the melanin drops, and the pigment of the area starts to lighten. And if the drop continues, it can spread throughout the body.
