The skin, as the body’s largest organ, performs a wide range of essential functions including protection, temperature regulation, and sensory reception. Structurally, it is made up of three main layers: the epidermis, dermis, and hypodermis, each with unique cell types like keratinocytes, melanocytes, and fibroblasts. Melanocytes are particularly important for skin pigmentation, as they produce melanin — the pigment that gives skin its color and helps protect against UV radiation. Vitiligo is a chronic skin condition where patches of skin lose their color due to damage or loss of melanocytes. Although significant progress has been made in understanding this disease, its exact causes remain unclear. Genetic, autoimmune, and environmental factors are all believed to play a role. Vitiligo affects around 1–4% of the world’s population, regardless of age, gender, or ethnicity. While it isn’t dangerous or contagious, it can have a deep psychological impact due to its visible nature. This article explores the normal histological structure and function of the skin, the pathological mechanisms behind vitiligo, and the main treatment options currently available — from topical therapies to phototherapy and surgical approaches. Early diagnosis and personalized treatment plans are emphasized as key factors in achieving better outcomes for patients
