Photobiomodulation vs. Red Light Therapy: Are They the Same?

Photobiomodulation vs. Red Light Therapy Are
They the Same?
2
Introduction
Red light therapy stands out as a rapidly
expanding trend in the health and wellness
domain. In 2022, the global red light therapy
market generated 997 million, and projections
indicate it will soar to 1.5 billion in the
coming decade. Despite this remarkable growth,
there is still considerable confusion surrounding
the terminology of light therapy, especially
photobiomodulation vs. red light therapy.

What Is Photobiomodulation?
Photobiomodulation (PBM), also known as low-level
laser therapy (LLLT) or cold laser therapy, is a
medical treatment that uses low-level light or
laser to stimulate cellular function and promote
tissue repair. This non-invasive therapy involves
exposing the body to low levels of light at
specific wavelengths, typically in the red or
near-infrared spectrum.

A Brief History of Light Therapy
In the early 20th century, Danish physician Niels
Ryberg Finsen's pioneering work earned him a
Nobel Prize for advancing the medical
applications of light. UV light gained
prominence in the 1920s for treating skin
conditions like psoriasis, while the 1980s saw
the use of fluorescent light to alleviate
Seasonal Affective Disorder. The latter part of
the 20th century and the 21st century witnessed
the rise of low-level laser therapy (LLLT) and
advancements in LED technology, making light
therapy more accessible. Today, it is widely
employed in medical and wellness settings,
addressing issues from skin disorders to mood
disorders, with ongoing research contributing to
its continual evolution.

Is Red Light Therapy Photobiomodulation?

• It is. However, it's crucial to highlight a key
  distinction
• Red light therapy falls under the category of
  photobiomodulation, utilizing specific
  wavelengths of red and near-infrared light. The
  light employed in RLT typically ranges between
  600-1400 nm.
• In simpler terms, various forms of
  photobiomodulation exist, and red light therapy
  stands out as one of the most widely embraced.
  However, there are many different light therapies
  including
• Green light therapy
• Yellow light therapy
• Polychromatic light therapy
• UV light therapy

6
Why Is Red Light Therapy Used for PBM?
Red light therapy is used for photobiomodulation
(PBM) because it utilizes specific wavelengths of
light, primarily in the red and near-infrared
spectrum, to stimulate cellular functions and
promote various physiological responses. The key
reasons red light is chosen for PBM include
Tissue Repair
Penetration Depth
Neurological Benefits
Anti-Inflammatory Effects
Optimal Absorption
Pain Management
Mitochondrial Stimulation

LED Red Light Therapy vs Cold Laser
LED Red Light Therapy
Feature
Cold Laser Therapy

• Uses light-emitting diodes (LEDs) to emit red and
  near-infrared light.

• Involves the use of a laser, which produces a
  focused and coherent beam of light.

Light Source

• Uses a broader range of wavelengths, including
  red light and near-infrared light.

• Usually uses a single, specific wavelength, often
  in the red or near-infrared range.

Wavelengths

• Generally has lower intensity compared to cold
  laser therapy.

• Can deliver a higher intensity of light due to
  the focused laser beam.

Intensity

• Often more affordable and accessible, with many
  devices designed for home use.

• More commonly used in clinical settings, and
  devices can be more expensive.

Cost and Accessibility

• User-friendly and often available in devices like
  light panels, masks, and handheld devices for
  home use.

• Typically requires more precise application due
  to the focused laser beam.

Wrapping Up
Red light therapy and photobiomodulation have the
potential to provide benefits across a diverse
range of conditions. They are frequently
recommended for addressing skin issues and
enhancing the quality of sleep. Despite the
potentially perplexing terminology, these
therapies hold significant promise for promoting
overall well-being. Consider selecting Hue Light
USA for your photobiomodulation devices and red
light therapy pads and mats.

FAQs
Is red light therapy the same as laser therapy?
1
Red light therapy and laser therapy are related
but not exactly the same. Both involve the use of
light for therapeutic purposes, but they differ
in terms of the type of light used, the devices
employed, and their intended applications.
Is all red light therapy the same?
2
Not all red light therapy is the same there can
be variations in terms of devices, wavelengths,
intensity, and intended applications.
Whats the difference between red light therapy
vs cold laser therapy?
3
Low-level laser therapy (LLLT) or
photobiomodulation is often referred to as cold
laser therapy. Consequently, red light therapy
falls under the category of cold laser therapy.
Today, photobiomodulation therapy is the more
widely used term compared to cold laser therapy.
