The Science of Light
Scientific studies have confirmed the effectiveness of 414-430 nanometer (nm)
blue light, and 630-660nm red light in eliminating acne forming bacteria and
promoting healing and the production of collagen in the dermal layer of the skin.
A study published in the Journal of Cosmetic Dermatology in 2006 outlined red
light LED’s ability to energize the cells, producing increased levels of collagen
and elastin. This increased cellular activity provides for firmer, smoother and more
naturally toned skin, reducing the appearance of fine lines and wrinkles without
producing adverse side-effects.
A 2006 Mount Sinai scientific study stated that “combinations of blue and red
light therapy have excellent potential in the treatment of mild to moderate acne.
Additionally, the treatment appears to be both pain and side-effect free.”
These studies expanded the findings of the Imperial College of Science,
Technology and Medicine’s published study in 2000 in the British Journal of
Medicine outlining an 80% success rate with light therapy treatment of acne. The
study showed that blue light in the range of 415nm was effective at eliminating
the p-acne bacteria that is the most common cause of acne outbreaks. Red
light, in the 660nm range, was found to promote healing of lesions, activating
macrophages at the dermal layer and promoting cellular regeneration.
