to help speed healing for its astronauts in space. Today, research supports the use of LED devices for inflammatory skin issues, healing and scar reduction, acne, wrinkles, and sun damage.
“There is a photoreceptor in the skin cells that is activated by certain wavelengths of visible light and near-infrared light,” explains., who has co-authored most of the recent research about the skin benefits of LED and has been studying the technology since 2008. “This process is known as photobiomodulation and can trigger a cascade of reactions in the skin that results in more skin energy, calcium changes, oxygen changes, and fibroblast stimulation among other reactions.
The technology has support among health-care professionals outside western medicine. “There’s enough research that makes LED therapy impossible to ignore,” says acupuncturist and herbalist“I find that it calms skin and also helps circulation and fluid movement in the face very similar to other skin treatments we do in traditional Chinese medicine.”
But they are an investment. The density and quality of LED diodes or “bulbs” typically correlate with efficacy and therefore a higher price. In fact, many pros say LED devices that retail for less than $200 or $300 probably aren’t worth it. But if you look at these tools and wonder what sets them apart from just a red flashlight, you’re not alone — plenty of businesses have used this skepticism as an opportunity, and the market is riddled with fakes or ineffective, low-quality versions.
Common criteria came up. “I look for devices that are FDA-cleared and that are practical for you to use and commit to,” says facialist, who has been researching LED for more than a decade and created her own LED bed for her studio. “If you want to really geek out, you could look at exact wavelengths and compare them to the research.” Jagdeo recommends looking for brands that have a medical and/or scientific advisory board and published clinical trial research to support its claims.
