Shedding light on the FDA's 510(k) approvals process: low-level laser therapy devices used in the treatment of androgenetic alopecia. (4th July 2019) - Wang, Sophie
Abstract: Introduction: Low-level laser therapy has demonstrated superior efficacy relative to other nonsurgical treatment options for the treatment of androgenetic alopecia. Methods: Records from a public U.S. FDA database for premarket approval of low-level laser therapy devices approved between January 1 2000 and July 15 2018 were reviewed. Results: 47 devices received 510(k) premarket approval, with an increasing number of devices available since 2007. More options are now available and product indications have expanded for use in a wider audience, including both men and women. Discussion: Growing recognition of lasers has led to an increasing number of devices available as well as innovative options in terms of design and convenience. In the past few years, these devices have adopted broader indications for use in both men and women. However, marketed indications have not been adequately explored and current devices on the market have the potential to mislead consumers.
