Photobiomodulation
Photobiomodulation (PBM) is a technology that is revolutionizing the fields of wellness and cellular regeneration by using light to stimulate various biological responses in the human body. This process relies on devices emitting specific light waves, notably via LEDs and lasers, to act in depth on cells and promote the management of symptoms linked to several inflammatory conditions, muscular pains and others. By combining specific wavelengths, such as red light or Low Level Laser Therapy, photobiomodulation stands out as a gentle, non-invasive and drug-free approach, particularly popular in the fields of dermatology, sports medicine and muscle recovery.
Photobiomodulation is based on a simple principle: the application of low-intensity light to trigger biological reactions in the body. The light sources used, such as LEDs and low-intensity lasers, emit specific wavelengths that are absorbed by the cells. Once absorbed, this light energy stimulates the production of collagen and ATP (adenosine triphosphate), an essential molecule for cellular energy metabolism, thus promoting regeneration and supporting the management of various symptoms. In dermatology, for example, LED photobiomodulation sessions are often employed to aid skin repair and promote a beneficial effect on the skin, while in physiotherapy, it can support individuals in the management of muscular pain or minor injuries.
The wavelengths of red or infrared light are particularly exploited for their in-depth effects, as they are able to penetrate tissues effectively without damaging them. The energy is absorbed by the mitochondria, the cells' energy centers, which can stimulate their activity and tissue regeneration. This process, sometimes referred to as laser therapy, uses a low-intensity device that differs from more aggressive treatments, making photobiomodulation accessible to a wide audience, including in everyday wellness approaches.
Photobiomodulation therapy is organized into sessions during which light waves are projected onto the area to be treated. The choice of wavelengths depends on the desired effects. For example, red LED light is often used for surface effects, such as skin care to smooth skin tone or reduce redness. Conversely, infrared wavelengths are chosen to penetrate more deeply and support muscle recovery processes or the management of certain inflammations.
Unlike high-intensity laser therapies, photobiomodulation works through a cascade of biological effects, without causing structural changes in the tissue. By stimulating mitochondria, it helps to :
These effects are mainly observed during regular sessions. Due to the low intensity of the light used, side effects are minimal. However, it is essential that these sessions are carried out under appropriate supervision to adjust the light parameters (such as wavelength and device power), thus ensuring optimum safety and enhanced efficacy.
One of the main attractions of LED photobiomodulation is its non-invasive nature. Unlike other methods that require physical interventions or heat applications, PBM relies solely on light to interact with cells. As a result, photobiomodulation sessions can be easily integrated into regular wellness or healthcare programs. Accompaniment centers, which embody a vision of supportive wellbeing, are exploring the use of photobiomodulation to accompany individuals affected by cancer and support their quality of life, as a complement to their main treatments. The absence of serious side effects and the safety of this process make it an accessible and adaptable option for a wide variety of needs.
The use of photobiomodulation is gradually expanding in a number of areas, thanks in particular to clinical studies conducted by renowned research centers. Here are some of the most common applications of PBM:
Photobiomodulation therefore appears to be an innovative approach, focused on stimulating cellular activity and gently managing numerous symptoms, thanks to the benefits of light.
