UVB Therapy

One of the most commonly prescribed psoriasis treatments for psoriasis, UVB phototherapy works by penetrating the skin and slowing the growth of affected cells. Treatment involves exposing skin to an artificial UVB light source—either broad or narrow—over multi-week treatments for 2-3 months. Low-level flare-ups may occur during UVB therapy, but can be treated with topical or oral anti-inflammatories during the process.
