Red light therapy is gaining traction among mainstream beauty shoppers, but experts believe consumers and brand marketing are focusing on the wrong metric.
Most light mask devices are marketed by LED count, but efficacy actually depends on power density and dose. These measurements are rarely disclosed to consumers but critical to whether light penetrates tissue and produces a biological response, Joylux, a company specializing in wellness devices, tells Personal Care Insights.
“The red light boom has created a market where visibility is confused with effectiveness,” says Colette Courtion, founder and CEO of Joylux. The company, based in Washington, US, offers high-tech home-use devices that address menopause-related health concerns.
The CEO tells us that while a device with many LEDs may look powerful, if each LED emits low power, the total delivered dose may never reach beneficial levels.
“Consumers assume more lights equal more power, but science tells a very different story.”
