The most commonly used instruments for diagnosing vitiligo currently are the Wood's lamp and the dermatoscope, with the Wood's lamp being used slightly more frequently in clinical settings. After the appearance of white patches on the body, one can first visit the dermatology department of a formal hospital for an examination with the Wood's lamp. If it is vitiligo, the patches will appear brightly white under the lamp, with clear edges. This disease has a certain degree of recurrence, and it is crucial to undergo formal treatment once diagnosed. During treatment, it is advisable to enhance physical exercise, boost immunity, and largely avoid eating spicy and irritating foods. Treatment can include oral medication, topical medication, and the use of a 308 nm UVB laser, which can accelerate recovery. It's beneficial to consume foods rich in black pigments, and it is advisable to avoid consuming excessive amounts of Vitamin C-rich foods. Persisting with the treatment usually yields good results.
