What is light therapy and how does it work?
Light therapy uses LEDs to produce specific natural wavelengths (colors) of light to stimulate, heal, regenerate, and protect cells that have either been injured, are degenerating, or else are at risk of dying. With the correct wavelength (color) for the condition, LED therapy has proven to be a non-invasive, safe, and side-effect free treatment for both medical and cosmetic use.
In this therapy form, LEDs are placed near or in contact with the skin and boost the energy level of the cells below the skin’s surface. Energizing cells by using light therapy boost their activity as it stimulates the mitochondria, which is the energy center within each cell and are essential for cellular repair and health. This process triggers a chain of reactions that can:
- Accelerate wound healing and tissue regeneration
- Increase circulation
- Reduce acute inflammation
- Help restore normal cellular function
- Reduce acute and chronic pain
Clinical studies are exploring the diverse potential of using light therapy and have shown that it has many health benefits. Light therapy can be used for applications such as pain management, improve post workout recovery, depression, wound healing, skin treatment, slowing down the progression of Alzheimer and Parkinson’s disease, … and many other purposes.
With this understanding, light therapy has made major progress in obtaining recognition from beauty specialists, chiropractors, medical doctors, massage therapists, athletic trainers, …. and also from people using light therapy at their home.
Effect of LED wavelength on the body
Red light (between 623 and 700nm): penetrates deeper into the skin to improve skin texture. It stimulates skin circulation, improves elasticity and skin tone, and eliminates fine lines, wrinkles, crow's feet and pigmentation. This wavelength repairs skin damage and stimulates the removal of waste products. Red light is also effective for fat loss and cellulite reduction.
Near-infrared light (NIR) is invisible to the human eye and has a wavelength in the 700nm and 1100nm range. It delivers energy to the body’s cells and can pass through bone to assist with healing deep wounds, muscle aches, nerve injury or joint pain. For optimizing brain health, a special helmet (HLM001) has been developed with LEDs at 1070nm for penetration through the skull bone into the brain cells.
Red light and near-infrared work best delivered in parallel, providing a greater range of benefits to the body’s cells and tissues.
Blue light (470nm) gets least deep into the skin and works mainly superficially. This wavelength helps calm and heal existing blemishes and reduces future breakouts by eliminating acne-causing bacteria. This will reduce blemishes and redness and eliminate and/or prevent skin inflammation.
Yellow light (590nm) reduces inflammation by promoting circulation and removing toxins. This wavelength improves oxygen in the skin cells, instantly giving the skin extra energy and suppleness. Visible redness caused by rosacea or other skin conditions are reduced.
Is LED light therapy the same as laser therapy?
No, LED light therapy is different from laser therapy because it does not cause damage to the skin surface. Laser works by causing controlled damage to the outer layer of the skin, which then induces tissue repair. LED light therapy bypasses this harsh step by directly stimulating regeneration of the skin. The light emitted by LED light therapy penetrates roughly 5mm below the skin’s surface.
