Does Red Light Therapy Live Up To The Hype?

Red light therapy (RLT) is designed for treating pain, wounds, and ulcers. But does it really work? And if so, does it work better than other existing treatments? The jury still seems to be out from a scientific standpoint, but there’s some evidence that RLT could have valuable benefits in some cases. Here’s what we know.

What is Red Light Therapy?

Red Light Therapy, or RLT, uses low-level wavelengths of red light. This therapy is controversial and mainly treats skin issues. It’s been used for cosmetic applications like wrinkle treatments and for more significant issues, such as wounds. Initially, scientists used RLT to grow plants in space. They found that intense light from red LEDs promoted both growth and photosynthesis. 

How Does Red Light Therapy Work?

Scientists who use RLT believe that it works by producing a biochemical effect. That helps to strengthen the mitochondria in cells, which is where energy is generated. A molecule called ATP (adenosine triphosphate) is responsible for carrying energy, and RLT may be responsible for helping a cell create more of those molecules. That leads to better efficiency for the cell, along with damage repair and rejuvenation.

What Conditions Does Red Light Therapy Treat?

Red light therapy is thought to treat wrinkles, scars, and wounds, along with ulcers and chronic pain. It has also been used to encourage hair growth in alopecia patients and improve carpal tunnel syndrome. Additionally, RLT has been used in the treatment of a number of conditions, such as:

• Diabetic foot ulcers
• Psoriasis lesions
• Sun damage
• Osteoarthritis
• Inflammation

Insurance companies typically don’t cover this treatment for most conditions. There is still controversy and argument about whether it’s effective or any more valuable than current treatment options. At this point, RLT is still considered experimental. 

Are There Risks With Red Light Therapy?

Most people consider RLT to be painless and safe. However, there have been reports of blistering and burns from red light therapy. Eye damage is also a potential risk, as is the case with nearly any type of laser. Another potential risk may be that RLT may not work, in which case the condition being treated could continue to progress while RLT is being pursued.

Does Red Light Therapy Do What It Promises?

Some people insist that RLT works for their conditions, while others say it is not effective. There are promising results for some skin conditions, but the scientific community hasn’t reached a consensus about the treatment’s potential benefits. Adding RLT to our skincare regimens may not hurt, but asking a doctor first may still be the right choice. 

It’s easy to buy an RLT device online, but be aware of what’s really offered. We want to choose products that are safe and effective. For that, a doctor’s guidance or recommendation might be the most valuable part of the equation. Then we can make informed choices as to whether RLT may be the right treatment option.
