Light Therapy Research and Studies


Light therapy is no longer a secret known only to the few.

The incredible benefits of light therapy (bright, red and blue) and the safety of natural light treatment are spreading like wild-fire around the world – And for good reasons.

Not long ago, light therapy was only available in special clinics (and for a whole lot of money) but today there are many light therapy home devices that have the same benefits and can be available to you at home 24/7 – At a fraction of the cost.

But is light therapy safe? Does it really work? These are questions we want science to answer, right?

Meanwhile, bright light therapy is being recommended by doctors as a first-line treatment for seasonal depression.

Blue light therapy is used by more and more acne-sufferers to destroy acne-causing bacteria without the dangerous medications and without lotions and chemical laden creams.

Also, Blue light therapy has been used for the last decade in neonatal units to treat jaundice. Approximately 30,000 premature babies each year in America are treated with baths of blue light, thereby avoiding dangerous blood transfusions.

Here you’ll find the most recent light therapy research and studies about light therapy – Whether it’s bright light therapy, blue light therapy and red light therapy – And all the proof that you need about the safety of this natural and non-invasive treatment, along with how well it works.

Red Light Therapy for Skin (Anti-Aging, Acne)


1. The International Center for Cosmetic Medicine in Australia (2007) finds the anti-aging and skin-rejuvenating benefits of red light therapy:

At 12-week follow-up, 91% of subjects reported improved skin tone, and 82% reported enhanced smoothness of skin in the treatment area.”

2. The Department of Dermatology, Seoul National University College of Medicine in Korea (2007) finds that red light therapy alone is effective for Acne Vulgaris:

The percent improvement in noninflammatory and inflammatory lesion counts of the treated side was significant compared to the control side”

3. The Unit of Dermatology, Imperial College of Science, Technology and Medicine, Hammersmith Hospital, London (2000) finds the superior benefits of combined red and blue light therapy for Acne Vulgaris:

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), benzoyl peroxide (at weeks 8 and 12) or white light (at each assessment).

The final mean improvement in comedones by using blue-red light was 58% (95% confidence interval 45-71″

4.  The Institute of Micro and Nanomaterials, University of Ulm, Germany finds the powerful combo of green tea and red light therapy for skin-rejuvenation:

After 2 months of extreme oxidative stress, green tea-filled cotton pads were placed once per day for 20 minutes onto the skin before treatment with an array of light-emitting diodes (central wavelength 670 nm, dermal dose 4 J/cm2).
RESULTS: Rejuvenated skin, reduced wrinkle levels, and juvenile complexion, previously realized in 10

months of light treatment alone were realized in 1 month.”

5.    The Department of Dermatology, National Medical Center, Korea finds the remarkable ability of red light therapy to boost collagen and elastin production:

Objectively measured data showed significant reductions of wrinkles (maximum: 36%) and increases of skin elasticity (maximum: 19%) compared to baseline on the treated face in the three treatment groups.

Histologically, a marked increase in the amount of collagen and elastic fibers in all treatment groups was observed”

Blue Light Therapy for Acne

1. A study conducted by the Clinical Aesthetic Journal in 2009 found a significant reduction in acne lesions, blackheads and white heads after self-application of blue light therapy, as you can see in the pictures below:

This 28-year old male patient had the first outbreak of acne at the age of 23. Baseline (a) and after the eight-week treatment period (b). The total number of lesions had reduced by 94 percent. The number of open comedones was reduced by 100 percent, the number of closed comedones was reduced by 100 percent, and the number of papules was reduced by 84 percent.

Infrared Light Therapy for Cancer


1.  NASA Research department discovered the phenomenal benefits of infrared light therapy for painful side effects of cancer chemotherapy and radiations:

Using this technology as a healing agent was phenomenal,” said Dr. Donna Salzman, clinical trial principal investigator and director of clinical services and education at the Bone Marrow Transplant and Cellular Therapy Unit at the University of Alabama at Birmingham Hospital.

“The HEALS device was well tolerated with no adverse affects to our bone marrow and stem cell transplant patients.”

Infrared Light Therapy for Wound Healing (This includes scars, Rosacea etc)


1.  The Department of Neurology, Medical College of Wisconsin, USA discovers the amazing infrared light therapy ability to speed up wound healing:

We believe that the use of NASA LED for light therapy alone, and in conjunction with hyperbaric oxygen, will greatly enhance the natural wound healing process, and more quickly return the patient to a preinjury/illness level of activity.

This work is supported and managed through the NASA Marshall Space Flight Center-SBIR Program”
