Dr. Zain, Heather, and Courtney explain vitiligo (loss of melanocytes causing flat, milky-white patches), how common it is, key subtypes, possible causes/triggers (autoimmune links, genetics, stress, trauma, sunburn, chemical exposures), and how it’s diagnosed (often clinically, sometimes with a Wood’s lamp). They cover risks like sunburn and increased skin-cancer risk in depigmented areas, stigma and mental-health support, and treatment options including topical steroids/calcineurin inhibitors, topical JAK inhibitor ruxolitinib (Opzelura), narrowband UVB/excimer laser, select procedures/grafting, camouflage makeup, and rare full depigmentation with monobenzone for extensive cases.
