Some interesting extracts from a promotional brochure `New Uses Emerge of Light-Emitting Diode Technology‘. Dr. Tony Chu is known to several of the UK members of rosacea-support.
The scientific literature demonstrates that infrared light penetrates tissue more effectively than visible light,” Dr. Calderhead added. “Intensity is also important, and LEDs are ideal in this regard. LED therapy is effective, non-invasive, painless, free of side effects, easy to apply, and well tolerated by all ages and all types of patients,” Dr. Calderhead said. “I think that LED therapy is the medicine of the new millennium.”
Alternating red (633 nm) and blue LED light (415 nm) in a series of eight sessions shows promising results in the treatment of mild to severe acne, according to Tony Chu, M.D., consultant dermatologist, substituting presenter for Bruce Russell, M.D. “Dr. Russell showed that LED red-blue therapy gave significantly better results than blue light, oral antibiotics, and topical therapy,” Dr. Chu said. “Results with the LED included 81% reduction in lesion count at 12 weeks and marked reduction in pore size, with no damage to the sebaceous gland.” Dr. Chu is head of dermatology at Hammersmith Hospital in London. According to Dr. Chu, Propionibacterium acnes absorbs blue light, which reacts with intracellular coproporphyrin III to produce singlet oxygen which destroys only bacteria and not the surrounding tissue. “The rationale behind using red and blue light is that red light has been used for many years to accelerate healing in chronic leg ulcers and non-healing lesions,” Dr. Chu said. “It is thought to have an anti-inflammatory effect and to work via cytokine induction.” How red and blue light is used alternately reduces sebum excretion and post treatment flare-up needs to be further investigated, he added.
“Initial clinical results suggest that the Omnilux LED system from PhotoTherapeutics, Inc. (Lake Forest, Calif., and Manchester, U.K.) will have a pivotal role in pain management,” according to R. Glen Calderhead, M.Sc., Ph.D., F.R.S.M. “Studies show that the pain transmission process can be attenuated by phototherapy,” said Dr. Calderhead. “The 830 nm light activates production of endorphins and blocks pain transmitting chemicals, causing non-narcotic analgesia. Recent studies have proven the efficacy of this wavelength in the management of sports and muscle injuries.
