This past summer, the journal Frontiers in Medicine <a href="https://www.frontiersin.org/articles/10.3389/fmed.2019.00161/full" target="_blank">published</a> an issue dedicated to photomedicine, and its 12 articles have an overwhelming effect similar to Joovv’s marketing copy, covering dermatological concerns like aging, skin cancer, and psoriasis as well as autoimmune diseases like type 1 diabetes. I like the way a 2016 journal article phrases it with a bad joke that gives away the researcher’s quiet exuberance: After a brief overview of peer-reviewed light-therapy treatments (for arthritis, hearing loss, and chemotherapy side effects), the conclusion states that “after decades confined to the ‘scientific wasteland,’ [photobiomodulation] may be finally emerging into the light of day (pun intended).”</blockquote>
