Vitiligo and evidence based Vitiligo and evidence based dermatologydermatology
Dermatologists are prescribing less PUVA in favour of UVB
Growing introduction of combined treatments targeted UVB + “active” topicals
Repigmentation rates show the therapeutic success of focused microphototherapy which is more remarkable when used in combination
Vitiligo and evidence based Vitiligo and evidence based dermatologydermatology
Both BIOSKIN® and Potent topical corticosterod preparations alone are the first line treatment in vitiligo vulgaris affecting less than 10% of the skin surface
Association of these 2 treatments gives better results, with very high repigmentation rate in more than 90% of patients
High repigmentation rates are observed also for other combination treatments, while Tacrolimus and Pimecrolimus but not phenylalanine are relatively active when applied without UVB irradiation
