Although LED Light Therapy has only recently come to the forefront of public awareness as a cosmetic treatment for aging, Light Therapy itself (also known as Photo Therapy) is certainly NOT a new technology. In fact its roots can be traced as far back as ancient times with a number of references in Greek, Roman and Indian cultures to light therapy. Ancient Egyptians believed bathing in various colored light would promote healing of associated ailments.
In 1903 Danish scientist Niels Ryberg Finsen was awarded a Nobel Prize in Physiology or Medicine for his work in light therapy, for a time following this, light therapy was widely used, however was shortly replaced with pharmaceutical products with the rise of the pharmaceutical industry.
In more recent times, doctors working at the Medical University of Wisconsin discovered that LED Light (light emitting diode technology developed by NASA for plant growth in space) had the same healing benefits that were uncovered in previous light therapy research. LED light was proven to deliver additional energy to the cell, accelerating cellular healing. ozmask.com
