Photobiomodulation and Photodynamic Therapy: The Power of Cold Laser for Health

Medicine has evolved tremendously in recent decades, incorporating innovative technologies that allow for more effective treatment of diseases with fewer side effects. Among these innovations, Photobiomodulation (PBM) and Photodynamic Therapy (PDT) have gained recognition as noninvasive methods for improving health at the cellular level.

But what exactly are these therapies and how can they benefit us?

What is Photobiomodulation (PBM)?

Photobiomodulation, also known as low-level laser therapy (LLLT) or cold laser, is a technique that uses specific wavelengths of red and infrared light to stimulate biological processes in the body. Unlike surgical lasers, which cut or cauterize tissue, low-level lasers do not generate heat or damage cells.

Numerous studies have shown that photobiomodulation can:

✔️ Reduce inflammation and pain in conditions such as arthritis and muscle injuries.

✔️ Accelerate wound healing by stimulating cell regeneration.

✔️ Improve blood circulation and tissue oxygenation.

✔️ Increase the production of ATP , the molecule responsible for cellular energy, optimizing cellular metabolism.

✔️ Improve brain health , with applications in neurological disorders and post-stroke recovery.

Photobiomodulation is widely used in sports medicine, physiotherapy, dentistry, dermatology and neurology, due to its ability to accelerate recovery without adverse side effects.

What is Photodynamic Therapy (PDT)?

Photodynamic therapy is a treatment that combines a photosensitizing compound with a specific light source to activate chemical processes within the body. This technique is especially useful in eliminating harmful cells, such as bacteria, viruses, and tumor cells.

The mechanism of action of PDT is based on:

1. Application of a photosensitizer, such as riboflavin or curcumin, which is absorbed into the target tissues.

2. Irradiation with light of a specific wavelength, which activates the photosensitizer.

3. Production of reactive oxygen species (ROS), which attack and eliminate damaged or pathogenic cells.

   
   

PDT has been used successfully in:

• Treatment of certain types of cancer and precancerous lesions.

• Elimination of bacteria and viruses, helping to prevent infections.

• Reduction of acne and other dermatological conditions.

During the COVID-19 pandemic, doctors experimented with PDT using riboflavin and laser light to treat and prevent pneumonia, showing promising effects in reducing lung inflammation.

Uses of the Laser Photobiomodulation System

Application of photodynamic therapy with specialized equipment that emits red and blue light.

Advances in laser therapy technology have enabled the development of portable devices such as the Photobiomodulation System, which facilitates the application of photodynamic therapy and photobiomodulation in home and clinical settings.

This system has been designed to assist in:

1. Cardiovascular health and blood circulation

• It helps reduce blood viscosity, reducing the risk of thrombosis.

• It promotes blood circulation, benefiting people with hypertension or diabetes.

• Improves oxygen transport in the blood.

  
  

2. Reduction of inflammation and chronic pain

• Relieves pain in joints and muscles.

• It helps in the treatment of diseases such as arthritis and fibromyalgia.

• Accelerates recovery from sports injuries and fractures.

  
  

3. Strengthening the immune system

• It contributes to the elimination of pathogens thanks to antiviral photodynamic therapy.

• Helps prevent respiratory infections and pneumonia.

  
  

4. Neurological benefits

• Its impact on post-stroke recovery has been studied.

• It can promote memory and cognitive function.

  
  

5. Respiratory and nasal care

• Includes a nasal applicator that helps treat rhinitis, sinusitis, and other respiratory conditions.

• Improves brain oxygenation and sleep quality.

The Future of Medicine with Light

Photobiomodulation and photodynamic therapy are revolutionizing medicine, providing effective, safe, and side-effect-free alternatives to more aggressive conventional treatments. With their ability to reduce inflammation, relieve pain, improve circulation, and regenerate tissue, these therapies are ushering in a new era of healthcare.

As research continues, we're likely to see even more applications of these technologies, from treating chronic diseases to using them in athletic performance and longevity.
