The best time to treat vitiligo is as early as possible.
In the early stage of vitiligo, the area of depigmentation is usually relatively small, and the condition is less complex. At this time, the melanocytes have not been severely damaged over a wide range. Medical treatments such as topical corticosteroids, calcineurin inhibitors, and phototherapy can have a better chance to stimulate the remaining melanocytes to regenerate and produce pigment. As the disease progresses, the depigmented areas may expand and the skin structure and function can be more affected. So, early detection and prompt treatment play a crucial role in controlling the spread of vitiligo and improving the prognosis of the disease.
