This informative article explores the causes and challenges of vitiligo on the hands, a condition that can be psychologically burdensome and difficult to treat. Factors like trauma, UV exposure, chemical contact, and trace element deficiency contribute to its onset. The mechanism involves immune-mediated melanocyte destruction by T lymphocytes. Treatment options, including medication and 308nm excimer laser therapy, are discussed. Lifestyle recommendations for prevention are provided, emphasizing a positive mindset, balanced diet, regular exercise, and avoidance of triggering factors. Understanding and addressing hand vitiligo's complexities are essential for patients and professionals alike.

Excimer 308-nm light is a form of targeted phototherapy that delivers a specific wavelength (308 nm) of ultraviolet B (UVB) radiation using an excimer laser or an excimer lamp. Both have shown similar results regarding efficacy, but have technical differences.
