In normal condition, there are itching feeling in the vitiligo skin lesion areas, if there are inflammatory reaction is only limited to have some symptoms like burning, red patches, blister and so on after over exposed to the sunlight. This is because their skin lack of melanin pigments and can not block the irradiation of ultraviolet rays and induce the vitiligo in the skin lack of melanin pigments. If there are no other factors influence and vitiligo patients feel itching in their skin lesions that often means their illness state is still spreading.

The vitiligo often treated by the external used drug, this kind of drug often have photo toxicity and photo sensitiveness, after irradiated by the ultraviolet ray make the medicine stimulate the skin and cause subclinical inflammation finally induce the melanophore produce melanin pigments.
