What is light in the first place?
The sun emits an unthinkable amount of energy. For example, if you could place a piece of the sun the size of a pinhead on earth, you would not be able to get safely within 90 miles of it. This energy is called electromagnetic radiation or the electromagnetic spectrum. This energy travels to earth in waves, like sound, and the wavelengths are measured in meters.
Most of the sun’s energy (radiation) is harmful to us (gamma rays, x rays, most of the UV rays), and so is blocked by our atmosphere. But some of this tremendous energy reaches earth, and we call the visible portion of this energy “light.”
The wavelengths of visible light are tiny, ranging from 400 to 700 billionths of a meter as shown above. A billionth of a meter is called a nanometer, or nm. White light, as you likely know, contains all the colors of the rainbow. Therefore, a color can be defined by a range of tiny wavelengths as shown in the chart to the right.
So then, whether coming from the Sun or any type
of light bulb, light is actually a powerful electromagnetic energy traveling
at 186,000 miles per second. It is no wonder, then, that light has a powerful effect on living things.
What is Light Therapy?
Light therapy is a broad term to cover the use of light to promote healing
or maintain optimum health and balance. Light therapy is not new, revolutionary or space-aged, but has
been used in the medical practice of just about all cultures since the beginning
or recorded history. In fact, light therapy was used in the medical practice
of modern societies until the advent of antibiotics, when most natural remedies
were put aside in favor of medical “advancements.” Today, light
is once again being recognized as the most advanced form of treatment for
an ever growing list of conditions, including acne treatment.
Light Therapy for Natural Acne Treatment
Blue (400nm-495nm)
Although there are many acne light therapy products to choose from, and
many websites to wade through, light therapy for acne treatment is as simple
as this: blue light kills acne bacteria. The source or intensity of the blue
light is not important, it is the color that does the work. More >
Red (620nm-750nm)
When NASA brought red LEDs into space, they kicked off the modern use of
red light therapy. Studies have found – and our experience has shown – that
blue light as an acne treatment is more effective when used in conjunction
with red light. Because of the longer wavelength, red light is able to penetrate
more deeply into the skin than blue light, accelerating the body’s
own natural healing process. More >
Near-Infrared Energy (IR-A 750nm-1,500nm)
Infrared energy is invisible electromagnetic energy, just after visible
red light on the electromagnetic spectrum. These wavelengths are capable
of penetrating deep into the tissue, delivering energy to fuel many metabolic
processes directly related to effective acne treatment. More >
Lightwave CS™
LightWave CS™ has been carefully designed to take advantage of each of the above wavelengths to provide the most effective acne light currently available
for in-home use. More >
