A Summary of Research Leading to Approval of Light Therapy for Ance

July 2000 - British Journal of Dermatology

Red Light Aids Healing

Research reported in the British Journal of Dermatology (July 2000. PDF, opens new window) found that regular sessions under blue and red light has been shown to "radically" help clear acne in moderate and less severe cases.

"The consultant dermatologist Tony Chu sent 120 patients home with specially designed red and blue lamps to be used for 15 minutes each day. The results, published in the British Journal of Dermatology, show a 76% drop in visible spots over 12 weeks." Taken from a report by Simon Bowers.

The blue light, as described below, attacks the bacteria that causes the acne, and the red light has an anti-inflammatory and healing effect on the skin. In fact, research done by David Olszewski, co- author of the book "Light Years Ahead" has shown that skin heals almost 200% faster when exposed to red light.

Blue Light Kills Acne Bacteria

"Light gets at the core of what causes acne eruptions: P. acnes, the bacterial responsible for causing acne inflammation, pumps out tiny molecules called porphyrins. When those porphyrin are exposed to certain wavelengths of light, they produce free radicals that kill the bacteria. Without P. acnes around to cause inflammation, acne clears up."

"A low intensity blue light source (405 nm to 420 nm) has been studied for the treatment of mild to moderate inflammatory acne. In the study, two 15-minute exposures a week for a period of four weeks produced a 60 percent reduction in acne in 80 percent of patients. Reported remissions from acne lasted as long as three to eight months." American Academy of Dermatology (opens new window)

August 2002 - FDA Approves Light Therapy for Acne

The FDA approved blue light therapy for acne in August 2002.  The first approved system of treatment, ClearLight, is available through dermatologists. Patients are exposed to a blue light source for 15 minutes twice per week for 4weeks. Each treatment costs between $50 and $150 per session, making a full course of treatment an average of $800. Light therapy for acne is considered "cosmetic" and is therefore not covered by insurance.
