White patches on the skin occur due to a disease known as vitiligo. It is a skin condition that causes the skin's pigmentation to fade. Melanocytes, which are the cells that create melanin pigment, are destroyed. This is the reason the reason why it occurs. Melanin, the colour of pigmentation, gives hair, skin and eyes a dazzling colour. The theory is that a mix of environmental, autoimmune, and genetic causes could cause vitiligo. However, the precise cause still needs to be understood. The immune system may, in error, target and kill melanocytes due to an autoimmune reason.
The spots are white on the skin and form one of the early stages of vitiligo. The spots can appear small and grow larger as time passes. They can be found anywhere in the body; they tend to appear on areas that are exposed to sunlight, such as the hands, faces legs, hands, and arms and those on the exposed parts of the body (such as the mouth, nose, and so on.). Eyes, genitalia and other similar areas. )
