RED LIGHT THERAPY HISTORY
In 1893, a man named, Niels Finsen published a paper about the efffect of light on the skin.
He studied effects of natural sunlight and artificial lights on insects and amphibians.
He was convinced there was a health benefit to light.
Finsen later discovered that certain wavelengths of light can generate healing properties and was eventually able to demonstrate its effects on a skin condition called lupus vulgaris, which were very painful lesions that typically appeared on the neck and face. In 1895, Finsen was able to treat patients with ultraviolet light every day for at least 2 hours a day. To treat these patients, he used a lens and filter system to pass short wavelengths of light through the skin, which he thought killed the bacteria.
In 1895, Finsen founded the Finsen Institute for Phototherapy in Copenhagen, which was dedicated to studying the effects of light or phototherapy on health conditions. There were at least 800 lupus vulgaris patients treated at the Institute. Of those patients, there were at least half who were cured.Red light therapy (RLT) is a controversial therapeutic technique that uses red low-level wavelengths of light to treat skin issues, such as wrinkles, scars, and persistent wounds, among other conditions.
In the early 1990s, RLT was used by scientists to help grow plants in space. The scientists found that the intense light from red light-emitting diodes (LEDs) helped promote growth and photosynthesis of plant cells.
Red light was then studied for its potential application in medicine, more specifically to find out if RLT could increase energy inside human cells. The researchers hoped that RLT could be an effective way to treat the muscle atrophy, slow wound healing, and bone density issues caused by weightlessness during space travel.
When RLT is used with photosensitizing medications, it’s referred to as photodynamic therapy. In this type of therapy, the light only serves as an activating agent for the medication.
There are many different types of red light therapy. Red light beds found at salons are said to help reduce cosmetic skin issues, like stretch marks and wrinkles. Red light therapy used in an medical office setting may be used to treat more serious conditions, like psoriasis, slow-healing wounds, and even the side effects of chemotherapy.
While there’s a fair amount of evidence to show that RLT may be a promising treatment for certain conditions, there’s still a lot to learn about how it works, too.
THE STUDY ABOUT RED LIGHT TECHNOLOGY
Red light is thought to work by producing a biochemical effect in cells that strengthens the mitochondria. The mitochondria are the powerhouse of the cell — it’s where the cell’s energy is created. The energy-carrying molecule found in the cells of all living things is called ATP(adenosine triphosphate).
By increasing the function of the mitochondria using RLT, a cell can make more ATP. With more energy, cells can function more efficiently, rejuvenate themselves, and repair damage.
RLT is different from laser or intense pulsed light (IPL) therapies because it doesn’t cause damage to the skin surface. Laser and pulsed light therapies work by causing controlled damage to the outer layer of the skin, which then induces tissue repair. RLT bypasses this harsh step by directly stimulating regeneration of the skin. The light emitted by RLT penetrates roughly 5 millimeters below the skin’s surface.

RED LIGHT USES BY NASA
Just 40 years ago, NASA used red light to stimulate plant growth and cell repair. This technique was is to heal injuries astronauts had in space. This added bit of knowledge helped scientists advance their experiments, which now include the treatment of many skin conditions with the use of artificial colors of light. Later, this led to the discovery that wrinkles and other signs of aging can be diminished with the help of light therapy.
