Vitiligo: Symptoms, Causes & Treatment
البهاق
Vitiligo is a non-contagious skin disease in which areas of skin lose their color, appearing as white patches, because pigment cells stop producing melanin. It is not painful or physically dangerous and is treated with creams, phototherapy, and other options to restore or even out color.
What is Vitiligo?
Vitiligo is a chronic skin condition in which white patches appear on the skin because the pigment (melanin) cells lose their ability to produce melanin, the pigment responsible for skin and hair color. These patches vary in size and location and may slowly enlarge or stabilize over time.
Vitiligo is not a contagious or painful disease and does not threaten physical health, but it can greatly affect the psychological side and self-confidence because of its appearance, especially when it appears on the face and hands. It is thought to be an autoimmune disease in which the body attacks its pigment cells, and it may sometimes be linked to other immune diseases such as thyroid disorders.
Today several treatment options aim to restore color to the patches, stop their spread, or even out skin tone, including creams, phototherapy, and newer treatments. The degree of response varies from person to person and by patch location. Most importantly, psychological support and understanding that vitiligo is not dangerous are an essential part of coping with it, along with dermatologist follow-up to choose the most suitable option.
