Is Red Light Therapy Safe for Your Patients?

Red light laser therapy, otherwise known as low-level laser therapy (3LT®), is a promising emerging treatment used to treat a number of medical concerns including joint and back pain, among many others. Researchers have noted the effective biochemical and physiologic effects of therapy. 3LT® has specifically been shown to target inflammation reduction, tissue healing acceleration, and pain modulation. These positive effects have proven to pain practitioners that laser therapy is an effective and safe way to manage these chronic conditions.

Since the treatment is still new to the market, professionals and patients have many questions about its uses and safety concerns. Here’s why laser therapy for pain is perfectly safe for your patients. Of course, medical professionals must provide guidance for their patients. Here’s where you can start…

How Does Low-Level Laser Therapy Work?

Low-Level Laser Therapy encompasses light therapies that utilize lasers in the red and near-infrared (NIR) range. These devices emit LED light at specific wavelengths, penetrating into the skin and providing powerful therapeutic effects at the cellular level. 

These highly concentrated lasers stimulate cells to support the mitochondria, known as the “power generators” of the cell. As laser therapy is performed, the mitochondria absorb the light and increase the production of adenosine triphosphate (ATP), the cell’s fuel. The cells transform ATP into energy and cells become more energized, allowing them to perform their functions more efficiently as well as repair and regenerate damage.

Scientists have discovered under performance of mitochondria leads to adverse physical effects such as pain, and skin and immune deficiencies. Research has shown that light therapy in the red and NIR reduces pain for patients.

Is Low-Level Laser Therapy Safe?

3LT® is an extremely safe, non-invasive treatment and is not associated with any side effects at this time. The treatment is also fully painless.

The treatment is nontoxic and less harsh on the skin compared to topicals used to target the same concerns. 

As with any treatment, overuse and abuse of laser therapy could lead to damage of the skin or eyes if proper protection is not used. Proper handling of the devices is imperative to their effectiveness and safety. Only practitioners who are qualified and trained in these therapies should be providing these treatment solutions.

What is Low-Level Laser Therapy Used For?

The list of benefits for low-level laser therapy is extensive. Here are some of the reasons why practitioners in varied practices, use 3LT® to aid their patients: 

  • Relieves pain and inflammation associated with osteoarthritis and rheumatoid arthritis. 
  • Reduces chronic neck, shoulder, and low-back pain 
  • Reduces post op pain for: 
    • Coronary artery bypass graft surgery 
    • Coronary bypass surgery with internal mammary artery grafts 
    • Tibial fracture surgery 
    • Cesarean section 
    • Endodontic surgery 
    • Tonsillectomy
  • Reduces inflammation 
  • Aids in fat loss

3LT® has potential to improve patients’ overall health. By increasing cellular energy the treatment creates a positive chain reaction in the whole body. Similarly to how your energy levels affect your ability to perform at your best, whether that is in a sport, at work, or when facing obstacles, energized cells allow other parts of your body to perform at their peak.

Are There any Side Effects?

No short-term side effects have been observed in any clinical trials and long-term effects are unlikely. However, the treatment continues to be reviewed and tested for further examination.

Given the often severe side effects of drugs and medications, light therapy is a great alternative for patients looking to stay away from painkillers. With the current opioid crisis, keeping patients away from potentially dangerous and addictive drugs is a priority. 

Medical practitioners should consider 3LT® in their treatments and an alternative to prescription drugs. It is natural, safe, and effective. It can potentially treat many of the same symptoms and provide relief fast with none of the side effects.


As with any treatment, proper training and use of the device will ensure the safety of the treatment. 3LT® shows promising results in the treatment of numerous conditions including those of the skin, pain modulation, tissue restoration, and reducing inflammation. Within the scientific community, there is still continuing research and education in progress. However, 3LT® has shown to be a completely safe treatment with only positive outcomes for the patient.
