Dermatologists agree that these devices are generally safe for both in-office and at-home use. Better yet, “generally, LED light therapy is safe for all skin colors and types,” Dr. Shah says. “Side effects are uncommon but may include redness, swelling, itch, and dryness.”
If you’re taking any medications or using any topicals that make your skin more sensitive to light, this “can potentially increase your risk of side effects,” Dr. Shah explains, “so it’s best to discuss LED therapy with your doctor if you are taking any such medications.”
It is worth noting, though, that in 2019, one at-home LED face mask was pulled from shelves in what the company described as “an abundance of caution” regarding potential eye injury. “For a small subset of the population with certain underlying eye conditions, as well as for users taking medications which could enhance ocular photosensitivity, there is a theoretical risk of eye injury,” read the company’s statement at the time.
Overall, however, our dermatologists give the seal of approval for anyone who’s interested in adding a device to their skin-care regimen. “They may be a good option for people who are pregnant or potentially pregnant, or for an acne patient who doesn’t feel comfortable using prescription medications,” says Dr. Brod.
