In his study, Dr. Michael Hamblin mentioned that red light therapy, also called photobiomodulation, can help cells survive, heal, and control inflammation. 

He explained that the light stimulates mitochondria and calcium channels, boosting energy, protein production, and cell growth. 

It also lowers harmful molecules in stressed cells and reduces inflammation in joints, injuries, the brain, and lungs. 

According to his research, using the right amount of light is important, too little may not help, and too much can slow things down. Overall, he highlighted that red light therapy supports healing and keeps cells healthy.

In my experience, red light therapy is one of the most impactful tools for health,” Gary Brecka shared in an interview. 

“It works at the cellular level, boosting mitochondrial function and helping blood flow through tiny vessels in our body. 

That means more oxygen and nutrients reach your skin, muscles, joints, even the brain. The key is using the right kind of device, high-powered, properly designed red lights penetrate deeply and really make a difference. Even 10 to 20 minutes a day can improve energy, circulation, skin, and overall vitality.

Dr. Paul Anderson says red light therapy isn’t just skin-deep, it actually reaches your muscles, fat, and even the blood flowing through them. 

He explains that the red and near-infrared light helps your cells’ mitochondria produce more energy, which supports healing, reduces harmful free radicals, and boosts overall cellular function. 

“When you combine red and near-infrared light,” he says, “you’re hitting both surface tissues and deeper muscle layers, so your blood, immune cells, and metabolism all benefit.” 

Even simple, safe at-home devices can make a noticeable difference if used as directed, helping your body recover and stay energized.

Dr. Josh Axe says red light therapy isn’t just a beauty trend, it’s real science. He explains that when you use high-quality devices at the right wavelengths, red and near-infrared light penetrate your skin, helping your cells produce more collagen, reduce inflammation, and even boost your cellular energy. 

Over time, this can make your skin look smoother and younger while supporting tissue repair and overall health. 

Dr. Axe emphasizes that cheap devices often don’t work, but when done correctly, red light therapy can aid muscle recovery, support longevity, and improve your body’s natural healing.

In my experience,” Dr. Tony Youn shared in an interview, “red light therapy is a safe, low-risk way to improve your skin at home. 

The science is still evolving, but we see it energizes cells, helping with wrinkles, hydration, and firmness. 

Studies show real improvements after a couple of months, and the best part is, you don’t need expensive or invasive treatments, just a simple, consistent routine at home can make a noticeable difference.

Dr. Amir Karam says red light therapy is like giving your cells a little wake-up call. He explains that when your skin and scalp are exposed to the right red or infrared light, your cells start producing more energy, which helps boost collagen, improve skin texture, and support healthier, thicker hair. 

He points out that the magic really happens when you’re consistent, using it regularly over time brings real results. 

He also reminds us to pick a good device, follow safety tips, and remember that while it’s amazing for rejuvenation, it works best alongside your regular skincare routine.

Dr. Jordan Wagner says red light therapy and infrared light therapy aren’t just a fad, they can really help your body heal and function better. 

He says red light boosts blood flow and delivers oxygen and nutrients to your skin, which can improve collagen, reduce wrinkles, and help scars heal faster. 

Infrared light goes deeper, reaching muscles, joints, and nerves to reduce inflammation, repair tissue, and even support hair growth. Dr. Wagner mentions he uses it at home for inflammation, joint health, and better sleep.

Red light therapy shows promising benefits, including improved cell energy, collagen production, reduced inflammation, enhanced circulation, and skin rejuvenation. 

Doctors note results depend on device quality, wavelength, and consistent use. While generally safe, even at home, effects vary, and evidence during pregnancy is limited. Overall, it’s a supportive, low-risk therapy, not a miracle, but far from overrated.

Red light therapy is generally low risk during pregnancy, but you should be cautious because research is limited. 

Always consult your OB GYN before use. Avoid treating your abdomen or lower back and use only low intensity FDA cleared devices. 

Keep sessions short and focus on safer areas like your face, neck shoulders, arms and legs.
