Photobiomodulation: healing with light

Photobiomodulation treatment by led

Although the health benefits of light have been known for centuries, the specific study of Photobiomodulation (PBM) really started in the mid-20th century:

In 1967, Hungarian physicist Endre Mester published his research into Low Lever Laser Therapy (LLLT). Then, in the 1970s, NASA conducted important work on the subject.

Since then, more than 600 randomized controlled trials (RCTs) have been published using PBM devices, and the technology has been featured in more than 7,000 studies, including 600 in the year 2020 alone!

 How does photobiomodulation work?

Each treatment protocol is composed of 4 key and specific elements:

• the wave (or waves) to be used
• the way the wave is sent: continuously (to nourish the cells) or in the form of a pulse (to repair the cells) 
• the surface to be treated, which makes it possible to define the device to be used: ‘beam type’ or ‘single beam’ type 
• the duration of the application.

Focus: LED photobiomodulation

PBM uses light radiation to stimulate cells in the epidermis, dermis and hypodermis. These cells are nourished by irradiation:

• with just the right amount of energy to stimulate their biological response, allowing them to reactivate and heal
• in a gentle and risk-free way, which makes it possible to treat larger or smaller areas in a homogeneous way.
