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 .
