Thanks for writing in.
Whatever you have said is true.Sunbathing
is one of the treatment for vitiligo
We routinely advise all our patients to take sunlight for treating vitiligo.
We use phototherapy
in all patients of vitiligo and it works too.
When used with oral or topical photosensitizing agents the phototherapy with sun is effective.
You can try topical psoralens and sunlight for better faster repigmentation.
Hope this helps.
