Over the years, various treatment modalities have been explored to alleviate the symptoms and improve the quality of life for patients with psoriasis. Among these treatment options, lasers and lights have emerged as promising non-invasive approaches with significant efficacy. This review aims to provide an overview of the current understanding and clinical applications of lasers and lights in the management of psoriasis. We have discussed the mechanisms of action behind different laser and light therapies and their impact on psoriatic plaques. Additionally, we discuss the various types of lasers and lights utilized, including excimer lasers, pulsed dye lasers, and narrowband ultraviolet B (NB-UVB) phototherapy, highlighting their unique properties and clinical outcomes. Moreover, we have addressed important considerations related to patient selection, treatment protocols, and potential side effects associated with lasers and lights. We emphasize the need for proper evaluation, monitoring, and customization of treatment plans to ensure optimal outcomes and minimize adverse events.<\/jats:p>","DOI":"10.4103\/ijd.ijd_423_23","type":"journal-article","created":{"date-parts":[[2024,4,29]],"date-time":"2024-04-29T10:01:45Z","timestamp":1714384905000},"page":"159-164","update-policy":"https:\/\/doi.org\/10.1097\/lww.0000000000001000","source":"Crossref","is-referenced-by-count":3,"title":["Laser and Lights in Psoriasis"],"prefix":"10.4103","volume":"69","author":[{"given":"Aarti","family":"Sarda","sequence":"first","affiliation":[{"name":"From the Consultant Dermatologist, Wizderm Speciality Skin and Hair Clinic, New Delhi, India"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Varsha","family":"Vaidyanathan","sequence":"additional","affiliation":[{"name":"Consultant Dermatologist, Skinderm Centre, New Delhi, India"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Sudip","family":"Das","sequence":"additional","affiliation":[{"name":"Department of Dermatology, Calcutta National Medical College, Kolkata, West Bengal, India"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Abhishek","family":"De","sequence":"additional","affiliation":[{"name":"Department of Dermatology, Calcutta National Medical College, Kolkata, West Bengal, India"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"276","published-online":{"date-parts":[[2024,4,29]]},"reference":[{"key":"R1-20240829","doi-asserted-by":"crossref","first-page":"205","DOI":"10.1111\/jdv.13854","article-title":"A systematic review of worldwide epidemiology of psoriasis","volume":"31","author":"Michalek","year":"2017","journal-title":"J Eur Acad Dermatol Venereol"},{"key":"R2-20240829","doi-asserted-by":"crossref","first-page":"1945","DOI":"10.1001\/jama.2020.4006","article-title":"Pathophysiology, clinical presentation, and treatment of psoriasis: A review","volume":"323","author":"Armstrong","year":"2020","journal-title":"JAMA"},{"key":"R3-20240829","doi-asserted-by":"crossref","first-page":"471","DOI":"10.4103\/2229-5178.193906","article-title":"Psoriasis: Epidemiology, clinical features, co-morbidities, and clinical scoring","volume":"7","author":"Dogra","year":"2016","journal-title":"Indian Dermatol Online J"},{"key":"R4-20240829","doi-asserted-by":"crossref","first-page":"adv00032","DOI":"10.2340\/00015555-3386","article-title":"Psoriasis and treatment: Past, present and future aspects","volume":"100","author":"Reid","year":"2020","journal-title":"Acta Derm Venereol"},{"key":"R5-20240829","first-page":"229","article-title":"Treatment of psoriasis","volume":"24","author":"Goeckerman","year":"1925","journal-title":"Northwest Med"},{"key":"R6-20240829","doi-asserted-by":"crossref","first-page":"591","DOI":"10.1136\/bmj.2.4836.591","article-title":"The approach to psoriasis","volume":"2","author":"Ingram","year":"1953","journal-title":"Br Med J"},{"key":"R7-20240829","doi-asserted-by":"crossref","first-page":"176","DOI":"10.1097\/00000441-195102000-00009","article-title":"Therapeutic suppression of tissue reactivity.
