Blue light (415nm)
It has long been known that sunlight (UV) can improve acne, although some of the effect is due to superficial camouflage. However, because of photo ageing and medical side effects, UV radiation is not recommended as a safe treatment for acne.
More recently, a peak wavelength of 415nm, which is outside the UV range, has been found to be effective at treating acne (1). It is known that Propionibacterium acnes (P. acne) produce porphyrins during their normal life cycle (2). Porphyrins absorb light energy at the near UV and visible blue light spectrum. The irradiation of P. acnes with blue visible light (415nm) leads to photoexcitation of bacterial porphyrins, singlet oxygen production and eventually bacterial destruction (3).
Red light (660nm)
It has been found that exposure to 660nm low-level wavelengths release cytokines. Cytokines stimulate fibroblast proliferation and the production of growth factors, thus influencing the inflammatory process, healing and ultimately wound repair (4, 5, 6, 7,) and has been found to significantly improve postoperative open wounds.
Red/Blue light treatment
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"
How Long and Often Do I Use the Cleanlite ?
Each person's sensitivity to light is different. Normal exposure is between 15 to 30 minutes per day, at a recommended distance of about 45 cms.
When should I see results?
A difference in your skin should be visible within 4 weeks of consecutive daily use. It is not possible to guarantee success in every case.
Can I Use it More than Once a Day?
Some people use it for 15 minutes in the morning and 15 minutes at night.
Can it Only be Used on the Face?
It can be used on any part of the body, except genitalia.
Will I Get a Sunburn or Skin Cancer?
The wavelengths of light used in the Cleanlite are outside those that will cause damage to the skin, so there is no risk of sunburn or skin cancer.
Should I wear Goggles?
It is not neccessary unless you are particularly sensitive to bright light. The unit emits about 2500 lux at the recommended treatment distance of 43cms.
The light therapy appliances were developed together with the "Hera" engineers and then manufactured by DAVITA. This guarantees you a high and consistent quality and they are all made in Germany. It is one of the company's policies only to offer medical appliances which are clearly effective and approved. DAVITA fulfils the required technical and scientific prerequisites for the manufacture of high-quality light therapy appliances.
DAVITA is a member of the Society for Light Treatment and Biological Rhythms.
The Society for Light Treatment and Biological Rhythms is a non-profit making international organisation which was founded in 1988. Its sole purpose is the promotion of research, professional development and clinical use in the fields of light therapy and biological rhythms.
