Why LED Light Therapy can help your skin
Spring is here and Memorial Day weekend is just around the corner. You’re in the local shopping mall and take a glance to the left, and there it is …….Summer Sales Specials all pointing to the beach!
But what caught your attention was those bright little lights that just keep on going like the energizer bunny.
They’re called LED’s or a light emitting diode.
But what are light emitting diodes?
They’re everywhere….from Christmas trees, to televisions, to computer screens, skin care, to red light therapy units, LED’s performs multiple tasks but primarily they’re asked to illuminate something.
Light emitting diode
The tiny light bulb that we’ve come to know as light emitting diodes are cool to touch and won’t burn out.
Now, those are two important concepts to remember in the skin care industry because LED Light therapy has been proven to have skin rejuvenating benefits.
Can you remember back to the days of the ordinary incandescent Christmas tree bulb? They got hot even though they made the tree look great. Each string of lights was loaded with warnings about heat and fire hazards. Along came the led string (light emitting diodes) of Christmas lights and immediately changed that industry.
Well the same could be said of the skin care industry. Because light emitting diodes don’t have a filament it won’t burn out and it won’t get hot. LED’s are illuminated by electrons which are being transported in a semiconductor material.
History of Red Light Therapy
In 2003, the National Aeronautics Space Administration (NASA) began funding studies on the benefits of LED Red Light Therapy.
“LEDs provide light for plants grown on the Space Station as part of commercial experiments sponsored by industry. Researchers discovered the diodes also had many promising medical applications, prompting NASA to fund this research as well, through its Marshall Space Flight Center in Huntsville, Ala.
Biologists have found that cells exposed to near-infrared light from LEDs, which is energy just outside the visible range, grow 150 to 200 percent faster than cells not stimulated by such light. The light arrays increase energy inside cells that speed up the healing process.”
Infrared led facts:
The semiconductor material used for red light therapy units (infrared lights) that help heal the three layers of the skin (epidermis, dermis, and subcutaneous fat layer) is germanium. Germanium has high conductivity and less resistance to current flow. In layman’s terms this allows electrons to flow freely. Thus, the light you see and touch in an LED light is bright enough to light a Christmas tree and cool enough to touch.
Now, understanding how semiconductors work is important to your skin. The diode of a light emitting diode is comprised of two electrodes: one is an anode and the other a cathode. The diodes are responsible for conducting electrical current through the electrodes.
The diodes play an important role in red light therapy units because they can manufacture different types of light. The term for the diodes is photovoltaic cells and the three types of light produced by this process is direct current (DC), infrared light (IR), or ultraviolet (UV). LED’s emit the Infrared (IR) energy type of light most commonly referred to in LED Light Therapy units, electronic equipment like televisions, and computers.
How does the infrared light penetrate the layers of your skin?
Light is transported via wavelengths. “A wave can be thought of as a vibrating disturbance by which energy is transmitted. A wavelength (symbolized in chemistry by the Greek letter lambda) is the distance from the center of one peak of a wave to the center of the next peak of the next wave”
Our eyes are sensitive to light which lies in a very small region of the electromagnetic spectrum labeled “visible light”. Thus, we are able to view the some led lights and not others such as those outside the spectrum of visible light or infrared light.
The National Aeronautics Space Administration (NASA) performed years of studies on the effects of light and skin care. The end results were extremely positive which spawned an entire red light therapy industry. There is conclusive data to show that the effects of led light to your skin improves the healing time on cuts, wounds, and abrasions but it also has had significant effects on such skin conditions like eczema, psoriasis, acne, adult acne, anti aging, collagen, and skin rejuvenation.
Facts about wavelengths?
Many people become confused about the role a wavelength of light has in red light therapy. But first we provide a wavelength definition. Very simply put it is the distance from the top of one crest (a wave) to the top of another crest. If you’ve taken any physics course then maybe the term lambda comes to mind when referring to a wavelength symbol.
wavelength of light
Have you ever seen pictures or a film of the ocean? The waves produced by gravity represent energy that is moving through a medium. Many people concentrate on the movement of water but it’s actually what moves the water that creates the wave and the wavelength is the distance from the highest point of one wave to the highest point of a corresponding wave.
In addition to water, wave can travel in other mediums. The military uses radar and sonar. But it is light that provides the most intriguing aspect we want to explore because of its healing power.
If you take a glimpse around you, light waves are everywhere. The technical term is the electromagnetic spectrum. However, our eyes can only view a small portion of light as visible.
Does the term infrared light ring a bell?
What is the visible light spectrum?
We talked about this above. Now this is where wavelength comes into play. Our eyes can decipher light which has a wavelength to frequency of between 400 and 700 nanometers. The wavelength of infrared light is considered anything above 700 nanometers.
This is important because cells in the human body regenerate when exposed to different spectrum of light. In another article we noted that cells exposed to red light therapy regenerated at a pace 4,000 times faster than those exposed to green light therapy.
Red light wavelengths have the ability to reach deep down through all levels of the skin (from the epidermis, down to the dermis and beyond) stimulating cellular repair and increasing circulation. Red light therapy helps smooth wrinkles and fine lines resulting in a more youthful-looking, smoother, plumper and vibrant complexion. When combined with Infrared light wavelengths, this powerful combination delivers optimal skin rejuvenation results.
Infrared light therapy wavelengths, though not visible to the human eye, offer THE most powerful and deepest skin penetration of all colors in the light diode spectrum. Infrared rays can combat the signs of aging skin by speeding the skin’s healing process. They stimulate natural collagen and elastin production in the dermal and epidermal layers of the skin. They quickly repair and replenish damaged cells resulting from swelling and inflammation, cuts, diabetic wounds, incisions, bruises, torn muscle, lower back ache, sore joints, arthritis, carpal tunnel and much more.
LED Light Spectrum
Amber light wavelengths help give the skin a youthful glow. They help calm swelling and redness associated with rosacea and post-chemical facial treatments. Amber lights can help speed the healing of new burns and may also help fade age spots.
So what does all this mean with regard to red light therapy and skin care. The use of red light therapy affords an individual a non-invasive approach to skin care. The market has numerous red light therapy devices which provide infrared treatment to assist in the healing process.
Wavelength plays an important role in led light therapy and skin care.
NASA studies have shown that our skin reacts favorably to wavelengths between 400 and 700 nanometers. So, the lesson to be learned here is that successful red light therapy incorporates a blend of light that is both visible and infrared wavelength.
LED’s or light emitting diodes are the vehicle which transmit both the visible light and infrared light to the three layers of skin: the epidermis, dermis, and subcutaneous fat layer. This steady diet of light stimulates the collagen as well as the blood vessels including the veins, capillaries, and arteries.
So, in summary, what you really have is the entire process starting with light and then branching out into the skin and further transported into the blood vessels and other parts of the human body. All this brings a positive effect which provides non-invasive, cost-effective treatment which can repair damaged skin.
