Abstract：
Phototherapy has utility as a psoriatic therapy, given its relatively high clinical efficacy, low side effect profile, and lower cost compared to newer effective treatments like biologics and small molecules. Phototherapy has shown Psoriasis Area and Severity Index (PASI)-75 and PASI-90 rates comparable to those of biologics and small molecules, with similarly rapid onsets of action, rates of remission, and quality of life scores. Certain patients may particularly benefit from phototherapy, such as those with localized disease or contraindications to systemic immunomodulatory medication. Phototherapy can be more cost-effective than biologics and conveniently administered at home, making it a valuable therapeutic option for the right patient.
