Vitiligo is a condition where melanin is lost from the epidermis, leading to the formation of white patches on the skin surface; this condition is not related to the skin itself. Vitiligo generally progresses with an increase in the area and whiteness of the patches, or an increase in the number of patches on the body, but it does not develop into skin cancer. Once diagnosed with vitiligo, it is essential to seek standard treatment at the dermatology department of a formal hospital, because the treatment period is relatively long, requires long-term medication, and involves treatment with 308-nm excimer laser. During treatment, it is important to exercise to boost immunity and avoid spicy and irritating foods. Eating more black-colored foods and limiting the intake of foods rich in Vitamin C is advisable. Even after complete recovery, continuing medication for a while to consolidate the treatment is recommended.
