You may have heard of the terms low-level-light therapy or photobiomodulation. Both terms synonymously are used to describe the delivery of light energy to treat a variety of medical conditions.
So what is low-level light therapy? It’s the application of specific wavelengths of light energy to tissue to obtain therapeutic benefits. The energy delivered is then used to improve cellular performance. Low-level light therapy can be delivered through light emitting diode (LED) devices or cold lasers, and has a variety of applications across many medical fields.
The treatment is non-invasive, painless, requires no recovery time, and can be used on all skin types.
Originally developed by NASA for astronauts who could become injured or ill on long-term space missions, low-level-light therapy is used today as a safe and natural method of treating a variety of skin and pain conditions such as acne, anti-aging, and pain.
How it works
In the same way that plants use chlorophyll to convert sunlight into plant tissue, high intensity light emitting diodes (LEDs) utilizing specific, proven wavelengths of light can trigger a natural biostimulatory effect in human tissue. Research has shown that phototherapy can increase circulation, accelerate tissue repair, kill acne bacteria, decrease inflammation, improve skin tone, texture and clarity, as well as ease muscle and joint pain, stiffness, spasm, and arthritis.
Research indicates that cells absorb particles of light (photons) and transform their energy into adenosine triphosphate (ATP), the form of energy that cells utilize. The resulting elevation of ATP is then used to power metabolic processes; synthesize DNA, RNA, proteins, enzymes, and other products needed to repair or regenerate cell components; foster mitosis or cell proliferation; and restore homeostasis. Simply put, the LED light source provides compromised cells with added energy so the cells performance is enhanced. For example, fibroblast cells will increase collagen and elastic production in connective tissue.
