Phototherapy for Psoriasis: New Research and Insights

Purpose of Review The purpose of the review is to highlight some of the new findings on phototherapy treatment for psoriasis and present clinical pearls for the practitioner. Recent Findings Recent research has helped to further elucidate the molecular mechanisms of UV light in the treatment of psoriasis. New evidence regarding the combination of phototherapy with biologic agents and phototherapy's effect on quality of life is also highlighted. Summary Phototherapy remains an effective and viable option for patients seeking non-invasive and safe treatment of psoriasis. Further research is still needed to understand the exact immunological effects and molecular pathways regarding the response of the skin to UV light. Further research is also needed with combination treatment phototherapy and the newest biologic agents.
