What influencers promise and what studies show are two very different things.

Red light therapy has officially hit wellness cult status. It’s in facials, gyms, med spas, and even popping up in living rooms thanks to portable panels and glowing masks. Promises range from anti-aging miracles to pain relief, muscle recovery, better sleep, and even brain boosts. And sure, standing in front of a warm red glow feels relaxing—but is it actually doing anything?
Some studies show potential benefits, especially for skin and healing. But a lot of the hype is built on half-truths, cherry-picked data, and flat-out guesses. It’s the kind of trend that sounds science-y enough to believe but vague enough to avoid accountability. And because the wellness world is great at selling dreams, it’s easy to get swept up in the glow without asking too many questions. Here’s what you need to know before you buy into the light.
