Wouldn't UV light also be contraindicated in Vitiligo?
Phototherapy with photochemotherapy (PUVA) is a well-known and well-studied modality for the treatment of psoriasis, which involves systemic or topical administration of chemicals known as psoralens and administration of ultraviolet light in increasing dosages after requisite time gap. PUVA is also used in the treatment of widespread vitiligo with moderately good results, though it is being surpassed by ultraviolet B (UVB), which is equally or slightly more efficacious with fewer side effects.
Honestly, I didn't even know what Methoxsalen is, just chose the right answer because I know you can not give UV light to people with PCT...
puva also used in GVHD
