The author emphasizes the importance of healthy skepticism when it comes to the hype surrounding photobiomodulation, which uses light to stimulate healing. While the concept may seem scientifically sound, the reality is that most studies have been done on animals, not humans, and positive results in lab animals do not always translate to effective treatments for humans. The molecular mechanisms behind photobiomodulation are intriguing but do not guarantee clinical improvements. The commercialization of this technology has led to questionable claims and conflicts of interest from companies selling these services. Overall, a cautious approach is necessary when considering the potential benefits of photobiomodulation.
