Unveiling the Science and Benefits of Red Light Therapy


Photobiomodulation (super forgetful word) utilizes light within specific wavelengths. Red light therapy (RLT) is a type of photomedicine (much easier on the memory), which is the use of light to treat skin and other health conditions.



Red light has wavelengths between 620 to 750 nm. So how does it work? When photons (particles of light) are placed near the skin they enter tissues and activate chromophores (a part of a molecule that gives it its colour), which triggers changes in cells, according to the American Society for Laser Medicine & Surgery.


In addition, red light therapy also affects the mitochondria (the powerhouse of cells), generating ATP (energy) to promote healing, notes the PBM Foundation.


Near-infrared light, which is a longer wavelength light (up to 1,200 nm), is also used in PBM and is what we know as infrared saunas. While this light may appear red, in reality infrared light is not visible, and instead heats the body from within to drive physiological changes. That is the difference between red light and infrared you see!!



Possible OMG moments on why we do Red Light Therapy?


ENHANCES A YOUTHFUL LOOK IN THE SKIN


One of the more commonly cited benefits of red light therapy is its effects on skin. It can be used to address:


Acne

Fine lines and wrinkles

Hair growth

Redness


Red light therapy decreases inflammation to address redness, acne, and hair growth, also allowing topical or oral treatments for these conditions to work even better, says Jagdeo. In addition, when it comes to banishing breakouts, “red light therapy increases our immune defences against the bacteria associated with the formation of acne,” he adds.


For lines and wrinkles, these treatments target enzymes associated with the breakdown of collagen, and stimulate collagen production, according to the Cleveland Clinic.



HELPS HEAL WOUNDS


Whether you have an ulcer in your mouth or an open sore on your foot, the anti-inflammatory properties of red light have been shown to improve the body’s ability to heal, says Arany, who published a review in April 2019 in Advances in Skin and Wound Care on the topic. “Research in my lab shows that PBM can activate a potent growth factor that promotes tissue healing and regeneration,” he explains, something that could be especially important for oral wounds, research has shown.
