A Brief Intro to Low Level Light Therapy

Can colorful lighting have a real impact on your skin? It might sound like something out of a science fiction novel, but the future really is here. Low level light therapy (LLLT) or LED therapy is a popular procedure that might sound a little too good to be true—but you can feel and see its benefits right away.

You’ve seen the hype but might still be a bit lost on what LLLT is (and what all of those Ls even mean). Here’s an introduction into this growing procedure, its rich history and what it can do for you.

The History Behind LLLT

Low level light therapy is the name you’ll hear thrown around the beauty and esthetics industry, but if you want to get technical, you can also call LLLT photobiomodulation. But who has time for that?

In 1967, just seven years after the invention of the ruby laser, Hungarian scientist, Endre Mester, started playing around with the effects of light on skin and hair. Mester found that when he shined certain laser light on the backs of shaven mice, their hair would grow back quicker than their unshaven friends. That made Mester think—what would happen if this light was applied to humans?

Mester’s human trials showed immense promise for LLLT as a healing tool. Patients with non-healing skin ulcers finally saw skin regrowth. From there, LLLT has seen a lot of development with research and improvement FDA approved for more than a decade, and it’s only getting more popular from here.
