red/blue light treatment research

In the first study of its kind, conducted at Hammersmith Hospital, Dr Chu et al. evaluated the use of a mixed blue and red light (peaks at 415nm and 660nm) in the treatment of acne vulgaris. 107 subjects were randomised into four treatment groups. 1. Blue light. 2. Cool white light (placebo) 3. 5% benzoyl peroxide 4. Mixed blue and red light.

Treatment consisted of 15-minute irradiation in front of a portable light unit each day. (With the exact, special spec, tubes utilised by BeautySkin).

The red/blue mix had significantly better results than the other treatment groups. Improvements were clearly noticeable after only 4 weeks. After 12 weeks, the blue/red treatment achieved a mean improvement of 76% in inflammatory lesions and a mean improvement in comedones of 58%, which exceeded any of the other treatments.

the researchers concluded

"We propose that blue light and red light acts synergistically in improving acne by combining anti-bacterial and anti-inflammatory action, rendering phototherapy with blue-red light an effective and safe treatment for acne vulgaris".

By utilising the red/blue peak light-wave technology (Patent No: WO 00/32272, US 6, 183, 500 B1, EP 0 884 066 A2 ) the 'BeautySkin' is clearly proven as an effective acne treatment.

another study

The effective treatment of acne vulgaris by a high-intensity, narrow band 405–420 nm light source.

The data show more than an 80% response to 420nm acne phototherapy with a significant reduction of 59–67% of inflammatory acne lesions after only eight treatments of 8–15 minutes. The reduction in lesions was steady in the follow-ups at 2, 4 and 8 weeks after the end of therapy. Prolonged remission was evident in the 8 weeks after the end of therapy. No adverse effects or patient discomfort were noted in any of the patients.

Acne phototherapy by high intensity, narrow band 405–420nm light is proven to be an attractive, fast, effective, non-invasive alternative to current topical and parenteral anti-acne remedies.
