Why Red Light Makes Blue Light Acne Treatment Better


Blue light is an effective acne treatment with a long list of benefits. However, red light therapy has its own very powerful benefits, and research has proven that the combination of red and blue light is even more effective for acne treatment than blue light alone.

July 2000 - British Journal of Dermatology says: "We found a final mean improvement of 76% in inflammatory lesions using a combined blue±red light radiation which was significantly superior to those achieved by blue light or benzoyl peroxide."

Red Light Speeds Acne Clearing, Prevents Scarring & Reduces Existing Acne Scars

Red light reduces inflammation (redness and swelling), speeds clearing and helps prevent new scars.

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 Does Red Light Work in Acne Treatment?

When different wavelengths (colors) of light shine on the skin, they are absorbed into the skin, setting off natural processes within it. Different results are achieved depending on the color of the light. Red light is known to increase blood flow and oxygen flow, accelerate the skin’s natural healing processes, and reduce pain.


Visible red LED light is capable of penetrating the skin to a depth of 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 acne clearing, and reduces scarring – exactly what acne sufferers are looking for.

Research Supporting Red and Blue Light Acne Treatment

Just like blue light, red light for acne treatment is supported by independent research all over the world.

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." Read the full study @ PubMed.gov



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)"
