Red Light

  • Phototherapy with blue (415 nm) and red (660 nm) light in the treatment of acne vulgaris

    British Journal of Dermatology 2000; 142: 973±978

    "In this study we have evaluated the use of blue light (peak at 415 nm) and a mixed blue and red light (peaks at 415 and 660 nm) in the treatment of acne vulgaris. One hundred and seven patients with mild to moderate acne vulgaris were randomized into four treatment groups: blue light, mixed blue and red light, cool white light and 5% benzoyl peroxide cream."

    "The mechanism appears to be that a porphyrin (Coproporphyrin III) produced within P. acnes generates free radicals when irradiated by 420 nm and shorter wavelengths of light.[48] Particularly when applied over several days, these free radicals ultimately kill the bacteria.[49] Since porphyrins are not otherwise present in skin, and no UV light is employed, it appears to be safe, and has been licensed by the U.S. FDA."

  • Light-emitting diode 415 nm in the treatment of inflammatory acne: an open-label, multicentric, pilot investigation.

    PubMed.gov - 2006 Apr; 8(1):31-3.

    "Forty-five patients were treated with high-intensity pure blue light, 415 nm and 48 J/cm2, receiving two treatments of 20 minutes per week for a period of 4-8 weeks. Clinical assessment was performed at baseline, and 2, 4 and 8 weeks after treatment. A patient's therapeutic response was measured using a global improvement scoring system."

    "Instead, blue and red light wavelengths produced by a lightbox which the patient, all with moderate or mild acne, used for 15 minutes each day. At the end of a 12 week period, these patients on average showed a 76% decrease in the number of visible spots on the area treated."

  • Red light phototherapy alone is effective for acne vulgaris: randomized, single-blinded clinical trial.

    2007 Oct; 33(10):1228-33; discussion 1233.

    "The percent improvement in noninflammatory and inflammatory lesion counts of the treated side was significant compared to the control side (p<.005). VAS decreased from 3.9 to 1.9 on the treatment side and the difference between the treatment and control sides was significant at Week 8."

  • Phototherapy with blue (415 nm) and red (660 nm) light in the treatment of acne vulgaris.

    2000 May; 142(5):973-8.

    "Assessments were performed every 4 weeks. After 12 weeks of active treatment a mean improvement of 76% (95% confidence interval 66-87) in inflammatory lesions was achieved by the combined blue-red light phototherapy; this was significantly superior to that achieved by blue light (at weeks 4 and 8 but not week 12)"

Visible red light (630nm-700nm) therapy is an effective, scientifically and clinically proven acne treatment that speeds the skin’s natural healing process and efficiently prevents scarring. David Olszewski, EE, IE, and co-author of Light Years Ahead: The Illustrated Guide to Full Spectrum and Colored Light in Mindbody Healing discovered that there is a 200 percent increase in the speed at which skin heals when it is exposed to visible red light.

In fact, in 1903, Niels Finsen won the Nobel Prize in Physiology for his use of red light in small pox treatment for the acceleration of healing and the prevention of scarring. Finsen also used the same red light techniques to treat lupus patients, successfully aiding in the treatment of this often disfiguring disease.

How Red Light Works

LED visible red light therapy is a non-invasive procedure that allows you to use non-thermal, low-level light energy to activate the natural processes of the skin. It converts the energy from the light into energy within your skin cells, which can then be used for healing, reducing inflammation, and minimizing scarring.

When different parts (colors) of light shine on the skin, they are absorbed into the skin, setting off processes within the body. This is called often called photobiostimulation. Different results are achieved depending on the color of the light. In the case of visible red light, blood flow and oxygen flow are increased, the skin’s healing processes are accelerated, and pain is reduced.

Visible red LED light is capable of penetrating the skin to about 8 to 10 mm. Once absorbed, the light provides adequate energy to stimulate the body’s natural healing processes. This makes visible red light therapy an ideal acne treatment, as it decreases inflammation, speeds healing, and reduces scarring – exactly what acne sufferers are looking for.
