Their are prescription drugs that may be taken prior to phototherapy to increase sensitivity as well, such as the PABA used to make for PUVA therapy (the P in PUVA is the drug plus the UVA). Their are also specialized types of phototherapy units that dispense just UVA or UVB light, as well as narrow focused UV units and such.


Ladyandy,

I think the "P" in PUVA stands for Psoralen, not PABA (p-aminobenzoic acid); the even though PUVA is still a commonly used term, the P part usually now is one of the semisynthetic derivatives like oxypsoralen and such. All of which as you note are ferocious photosenitizers.
