Red Light Therapy Boom: What the Science Really Says as Masks, Mats and Beds Flood Beauty Market
Red-light therapy devices, including masks and beds, have rapidly expanded from clinics to U.S. homes and wellness centers, with sessions and products ranging from $49 to $860. Dermatologists say evidence supports benefits for pattern hair loss and some wrinkle reduction, but warn most claims outpace the science. FDA clearance indicates safety, not effectiveness. Broader wellness uses, such as for sleep or athletic recovery, lack strong data.
