Can Red Light Therapy Improve Your Skin? Dermatologists Share Benefits and Tips

The buzz around red light therapy is lighting up social media feeds, with influencers flaunting its home-use devices and claiming impressive skin benefits. But does this trendy treatment actually deliver results?

According to some studies, red light therapy shows promise, but dermatologists caution that more research is needed to fully back up the claims.

Red light therapy uses visible and near-infrared light to target skin concerns, explained Dr. Chris G. Adigun, a dermatologist at Dermatology & Laser Center of Chapel Hill. The treatment typically involves LED devices that emit specific wavelengths of light. Adigun described how these wavelengths stimulate components that improve skin quality while reducing those that degrade it. "It’s particularly useful for treating acne and skin rejuvenation, making it popular among a wide age range," she added.

Red light therapy also boasts anti-inflammatory and calming properties, noted Dr. Lauren Fine, medical director of Fine Dermatology in Chicago. On top of that, it offers "pro-aging" benefits like collagen stimulation, reducing wrinkles, and enhancing overall skin quality. And here’s a bonus: there’s no downtime required after use.

With its rising popularity on social media, at-home skincare devices like red light therapy units are becoming a hit. Dr. Fine mentioned that while the risks are "very little" for most users, some medications—like certain antibiotics and antihistamines—can make skin photosensitive, leading to unusual reactions to light. Individuals sensitive to heat-related skin changes might also need to steer clear of this treatment.

For those ready to give it a go, experts emphasized the importance of following the device’s instructions for optimal results. Dr. Adigun highlighted that proximity and exposure time are critical: the closer the device is to the skin and the longer the session (at least 10 minutes daily), the better the outcomes. But let’s be honest—committing to that daily ritual might not be realistic for everyone.

As always, dermatologists recommend consulting with a professional before diving into at-home red light therapy. Proper guidance can help ensure safety and effectiveness.
