Can red light therapy really deliver a beauty and health glow-up? Here's the science
Wellness influencers tout the therapy's power for everything from rejuvenating skin and hair to boosting longevity. Devices sold for at-home use abound. We look at the evidence behind the hype.

Red light therapy is currently trending as a 'holistic wellness' must-have, with influencers claiming it can treat everything from joint pain and wrinkles to hair loss and period cramps. While at-home devices like masks and wands are flooding the market, experts like Dr. Zakia Rahman of Stanford Medicine urge caution. The scientific reality is more nuanced than the social media hype suggests, as the efficacy of these devices depends heavily on specific wavelengths and consistent professional-grade application.
While some studies indicate potential benefits for skin health and inflammation, many consumer-grade products may lack the power or precision required to deliver noticeable results. Dermatologists emphasize that distinguishing between proven medical applications and marketing 'ray of hope' claims is crucial for consumers looking to invest in these often expensive wellness technologies.
