Vitiligo is a common depigmenting skin disorder primarily caused by the loss of melanocyte function in the skin. Using a vitiligo light therapy device is a common adjunctive treatment method. Its principle involves stimulating melanocyte regeneration and promoting pigment synthesis through irradiation with specific wavelengths of light. Different types and stages of vitiligo may require different light intensities and wavelengths.
When purchasing a light therapy device, ensure it has proper medical certification to guarantee its safety and effectiveness. Understand the device's wavelength range, as excimer light around 308 nanometers generally shows good therapeutic effects for vitiligo. Also, consider whether the illumination area meets your personal needs.
Before use, carefully read the instruction manual. Start with a low dose and gradually increase the duration or intensity of irradiation to avoid skin burns. During irradiation, properly protect your eyes and unaffected skin areas.
Regular follow-up visits to the hospital are necessary to adjust the irradiation plan according to disease progression. Do not rely solely on the light therapy device but also pay attention to other comprehensive treatments such as medication and psychological adjustment, in order to enhance treatment effectiveness and promote disease improvement.
