Scientific Direction<\/h2>\n\n\n\n<p>Finsen observed the effect of light on his own symptoms, which encouraged his interest in how targeted wavelengths could support comfort and healing [2,5].<\/p>\n\n\n\n<p>His medical training in Copenhagen helped him refine these ideas and begin exploring light\u2019s role in managing persistent skin disease [1,2].<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Emergence Of Phototherapy<\/h2>\n\n\n\n<p>Finsen noted that sunlight eased certain skin concerns and proposed that specific UV wavelengths could influence bacterial activity and tissue repair [3].<\/p>\n\n\n\n<p>He focused on lupus vulgaris, a severe form of skin tuberculosis, which lacked reliable treatment and caused long term distress for many patients [2,4].<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Development &amp; Clinical Progress<\/h2>\n\n\n\n<p>Filtered UV light showed potential to help suppress bacteria and support healing, and Finsen refined this approach through detailed laboratory work [2,3,6].<\/p>\n\n\n\n<p>By 1895 he treated lupus vulgaris patients using concentrated UV light, documenting results that marked a turning point in managing chronic skin disease [1,2].<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Expansion &amp; Global Impact<\/h2>\n\n\n\n<p>The Finsen Medical Light Institute opened in 1896 and welcomed patients from around the world, inspiring similar centres across Europe and North America [2,7].<\/p>\n\n\n\n<p>More than 800 individuals received treatment in the institute\u2019s early years, with many gaining significant improvement or resolution of long standing symptoms [4,7].<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Nobel Prize Recognition<\/h2>\n\n\n\n<p>In 1903 Finsen received the Nobel Prize in Physiology or Medicine for demonstrating that targeted light could treat disease and support healing [1,5].<\/p>\n\n\n\n<p>His health declined shortly afterward, yet his influence shaped a new field and established light based care as a recognised medical discipline [1].<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">How UV Phototherapy Works<\/h2>\n\n\n\n<figure class=\"wp-block-table\"><table class=\"has-fixed-layout\"><thead><tr><th>Application<\/th><th>Mechanism<\/th><\/tr><\/thead><tbody><tr><td>UVB or NB UVB<\/td><td>Calms immune activity and slows rapid cell growth [3]<\/td><\/tr><tr><td>UVA or PUVA<\/td><td>Supports deeper immune modulation [3,4]<\/td><\/tr><tr><td>Visible or red light<\/td><td>Aids repair and comfort in selected concerns<\/td><\/tr><tr><td>Photodynamic therapy<\/td><td>Uses light with a sensitiser to target cells [3]<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n<p><em>Table 1: Key applications and mechanisms of phototherapy<\/em><\/p>\n\n\n\n<p>UV phototherapy can help slow overactive immune cells in the skin, easing redness, thickening, and flaking in conditions such as psoriasis or eczema [3,4].<\/p>\n\n\n\n<figure class=\"wp-block-image size-large\"><img loading=\"lazy\" decoding=\"async\" width=\"1024\" height=\"576\" src=\"https:\/\/24squaretechnologies.com\/projects\/monderma-v3\/wp-content\/uploads\/2025\/06\/woman-with-at-home-red-light-phototherapy-device-1024x576.jpeg\" alt=\"\" class=\"wp-image-1000016856\" srcset=\"https:\/\/24squaretechnologies.com\/projects\/monderma-v3\/wp-content\/uploads\/2025\/06\/woman-with-at-home-red-light-phototherapy-device-1024x576.jpeg 1024w, https:\/\/24squaretechnologies.com\/projects\/monderma-v3\/wp-content\/uploads\/2025\/06\/woman-with-at-home-red-light-phototherapy-device-300x169.jpeg 300w, https:\/\/24squaretechnologies.com\/projects\/monderma-v3\/wp-content\/uploads\/2025\/06\/woman-with-at-home-red-light-phototherapy-device-768x432.jpeg 768w, https:\/\/24squaretechnologies.com\/projects\/monderma-v3\/wp-content\/uploads\/2025\/06\/woman-with-at-home-red-light-phototherapy-device-1536x864.jpeg 1536w, https:\/\/24squaretechnologies.com\/projects\/monderma-v3\/wp-content\/uploads\/2025\/06\/woman-with-at-home-red-light-phototherapy-device-1200x675.jpeg 1200w, https:\/\/24squaretechnologies.com\/projects\/monderma-v3\/wp-content\/uploads\/2025\/06\/woman-with-at-home-red-light-phototherapy-device-600x338.jpeg 600w, https:\/\/24squaretechnologies.com\/projects\/monderma-v3\/wp-content\/uploads\/2025\/06\/woman-with-at-home-red-light-phototherapy-device.jpeg 1920w\" sizes=\"auto, (max-width: 1024px) 100vw, 1024px\" \/><\/figure>\n\n\n\n<h2 class=\"wp-block-heading\">Influence On Modern Care<\/h2>\n\n\n\n<p>Light based therapies now support conditions beyond dermatology, including neonatal jaundice and specific precancerous lesions [4,6].<\/p>\n\n\n\n<p>Research continues to refine wavelength selection and delivery, offering more targeted approaches that build on Finsen\u2019s original work [3,4].<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Conclusion<\/h2>\n\n\n\n<p>Phototherapy can be effective for chronic skin conditions, yet personalised prescription skincare often provides targeted support for acne, ageing, hyperpigmentation, or rosacea.
