LED therapy is generally considered safe for most people (in fact, some research papers have stated33 that there is “an almost complete absence of side effects” associated with red light therapy treatment). Additionally, the American Academy of Dermatology deems LED treatment safe.
Of course, there are things to keep in mind when using the tools.
First and foremost, you should find a quality product (more on that below). Because as experts have explained to us, less-than-stellar options have flooded the market, resulting in a lot of poorly made options in the hands of users. “Unless the LED light is the correct wavelength, it’s not going to do anything; you might as well be using Christmas lights,” says esthetician Natalie Aguilar.
Anecdotal accounts reveal that some people find red light therapy to be irritating or bothersome to the eyes, but this can be remedied by wearing goggles.
Finally, always follow the instructions from the brand. Esthetician Aneta Zuraw, co-founder of Atelier Beauté, generally advises placing the device panel within 1 inch of the face, but certain manufacturers may have different protocols. “All programs, distance, and time vary per skin condition and device used,” she says.
