How does PUVA work in psoriasis?
There is also another option called “psoralen plus ultraviolet A” (PUVA) therapy. It involves exposing the skin to UVA light and using a medication known as “psoralen” too. The medication makes the skin more responsive to UVA light, increasing its effect.
Is PUVA therapy chemotherapy?

PUVA therapy is given either orally or by external application of methoxsalen (8- methoxypsoralen followed by UV-A irradiation.
What is PUVA treatment for vitiligo?
PUVA treatment increases the number of both inactive and active melanocytes ( Morison, 2008).
