Red Light Therapy
Red light therapy uses relatively long wavelengths of light (630nm to 700nm) to penetrate the skin and encourage healing, improve skin tone, increase circulation, and treat a number of chronic skin conditions like eczema and psoriasis. It is safe, painless, and delivers these results without the harmful effects of UVA and UVB light.
Red light therapy is effective because red light increases the production of adenosine triphosphate (ATP) from the cells’ mitochondria, which is the energy source of all cells. With an increase in ATP, skin cells have more energy to devote to optimal cell functioning, regeneration, and healing. Red light therapy also improves symptoms by:
- Triggering development of new capillaries and improving circulation for increasing oxygen nutrient delivery to the skin.
- Activating the lymphatic system.
- Stimulating DNA/RNA synthesis.
Red light also stimulates our sympathetic nervous system (the fight-or-flight response). Normally, this is not associated with healing, however, the sympathetic nervous response causes improved circulation and a decrease in inflammatory responses.
In short, improved blood flow from red light therapy can assist the skin’s natural healing properties.
UV light has some therapeutic effects on the skin’s surface; however, it does not penetrate the skin deeply enough. Red light penetrates to a truly therapeutic depth with no known side effects.
