If you've noticed red light therapy popping up everywhere lately, you're not imagining it. From skincare routines to recovery studios and at-home wellness devices, red and near-infrared light have become one of the biggest trends in wellness. But unlike some wellness crazes that seem to appear overnight, red light therapy has actually been studied for decades.

So, what exactly is it?

Red light therapy, also known as photobiomodulation, uses specific wavelengths of red and near-infrared light to interact with the body's cells. Researchers believe the light may influence cellular activity, including processes involved in energy production, inflammation, and tissue repair. And while it certainly isn't a cure-all, there is legitimate research behind many of the reasons people are turning to it.

One of the most popular uses is for skin. Studies have explored red light therapy for improving the appearance of wrinkles and supporting skin rejuvenation. Researchers have also looked at photobiomodulation for pain, inflammation, recovery and even hair growth. A 2025 review of 15 meta-analyses covering more than 200 randomized controlled trials, and more than 9,000 participants, found evidence of benefits for several specific health outcomes, although researchers noted that more high-quality research is still needed.

That's an important distinction, because red light therapy isn't magic…and it doesn't need to be.

Perhaps the appeal is that it fits so easily into the way we're thinking about wellness today. Instead of another complicated routine, it's something you can incorporate into a few quiet minutes of your day. You can use it while you're winding down, getting ready in the morning, or simply taking a little time for yourself.

And you don't need a dedicated wellness room to try it.

For a simple introduction, the EZLIFE Red Light Therapy Mask with Vibration is an easy place to start. Designed for facial use, the mask combines red light with vibration, perfect for a little refresh, while watching your favorite show.

Want to take the experience beyond your skincare routine? The Infrared Sauna Blanket with Red Light LED Therapy combines infrared heat with red-light technology in a compact format that can be used at home.

And maybe that's the best thing about this particular wellness trend: it doesn't require you to completely overhaul your life. It's simply another tool you can add to the things you're already doing to take care of yourself.

Move your body. Eat well. Get enough sleep. Drink your water. Take time to recover.

And if a little red light becomes part of that routine? Well, there's some pretty interesting science behind the glow.

What the Research Actually Shows

The 2025 review cited above didn't grade every claim people make about red light therapy—it focused on outcomes with enough randomized trial data to analyze using GRADE, the same certainty framework used across medicine. Here's a snapshot of what it found:

Outcome studied	What researchers found	Certainty of evidence
Hair density (androgenetic alopecia)	Significant increase	Moderate
Knee osteoarthritis-related disability	Significant improvement	Moderate
Age-related cognitive function	Significant improvement	Moderate
Fibromyalgia pain & fatigue	Significant improvement	Low
Tendinopathy pain	Modest reduction; no significant effect on muscle strength	Low / Very low

Worth noting: across all 35 outcomes the review examined, none reached "high" certainty, and the review didn't specifically evaluate skin rejuvenation or wrinkle outcomes—those claims come from smaller, separate studies. That's why researchers describe the evidence as promising but still developing, not settled.

Red Light Therapy: Frequently Asked Questions

Is red light therapy safe to use at home?

For most healthy adults, at-home red light devices are considered low-risk since they use non-thermal, low-intensity light rather than UV rays. That said, this isn't medical advice—check with your doctor first if you're pregnant, taking medication that increases light sensitivity, or managing a skin condition.

How often should I use it?

Most of the clinical trials referenced above used sessions several times a week over a period of weeks, not a single treatment. If you're trying an at-home device, following the manufacturer's recommended schedule matters more than the length of any one session.

Do I need eye protection?

Many red light devices, including masks, are bright enough that manufacturers recommend against staring directly into the light. Check your specific device's instructions—some include built-in eye protection or recommend keeping your eyes closed during use.

How long before I might notice a difference?

There's no universal timeline. In the studies above, benefits generally showed up after weeks of consistent use, not overnight. Individual results vary, and red light therapy works best as one part of a broader routine rather than a stand-alone fix.

Can it replace my skincare routine or medical treatment?

No. Red light therapy is best thought of as a complementary tool, not a replacement for prescribed treatment, skincare products, or medical care.
