Phototherapy or light therapy is classically referred to a heliotherapy. It consists of exposure to daylight or to specific wavelengths of light using polychromatic polarised light, lasers, light-emitting diodes, fluorescent lamps, dichroic lamps or very bright, full-spectrum light. The light is administered for a prescribed amount of time and, in some cases, at a specific time of day.
In 1903, a Nobel Prize in Medicine and Physiology was awarded to Niels Finsen. This was in recognition of his contribution to the treatment of diseases, especially lupus vulgaris, with concentrated light radiation, whereby he opened a new avenue for medical science. From this time the use of light in medical science has continued. In the 1950s the effects of light on jaundice in newborns was discovered. This today is one of the most commonly known uses of phototherapy, whereby newborn jaundice is treated with phototherapy by lowering the bilirubin levels in the baby’s blood through a process called photo-oxidation. Phototherapy has been used worldwide for nearly a century to treat chronic skin conditions such as psoriasis, vitiligo and severe eczema.
Today science has enabled us to innovate further in this area. The Senan Biotech phototherapy patch products have been developed to use natural wavelengths of light which stimulate specific acupressure points on the body. The patches use the principles of photobiology, which is the effects of light on living organisms, when using the patches, the body becomes a receiver of energy and an energy transmitter.
