Osmosis video - Vitiligo

Vitiligo is a skin condition characterized by patches of depigmentation that can affect any race or ethnicity, but is most noticeable in people with darker skin. Melanocytes, which secrete the pigment melanin, are responsible for skin color, and their loss or dysfunction causes vitiligo. The exact cause of melanocyte destruction is unknown, but genetics and environmental triggers may play a role. The main symptom is irregularly shaped patches of depigmentation, which can be small or large and may expand over time. Treatment includes cosmetic cover-up, topical and systemic immune suppressants, UV phototherapy, skin bleaching, and skin grafts. Sunscreen is also recommended to reduce the risk of skin cancer.
