Infrared (IR) VS Red Light therapy (RED LED)


This is where it gets a little tricky. The human eye can see wavelengths of light that range from 400- 700 nanometers. The human body can feel parts of the electromagnetic spectrum that cannot be seen, such as infrared heat!

Infrared heat and red light therapy are becoming progressively popular in the spa, wellness and beauty realms. They are often confused, but they are different and they do provide different benefits. We know both deliver amazing results, we see it all the time. Yet, they are often confused, but they are different and they do provide different benefits. Here is information you need to know about each, how they compare to each other and which benefits they provide.


The Science of Light Therapy


For ideal health, we humans require regular exposure to light! A great example is Vitamin D which comes from sunlight. The suns rays include the more commonly known ultraviolet light (UV), but more than half of its output is infrared. When it comes to visible light, violet colored light produces the most energy and red colored light provides the least.


As mentioned above, this spectrum classifies each form of energy by nanometers and its effect on the human physique. Nanometers are a unit of length equivalent to a billionth of a meter, and they are used to measure the wavelength of light. Since were comparing red light to infrared, its important to note their order on the spectrum.


Red light is visible and is most effective for use on the surface of the skin. Red light occupies the long endof the visible spectrum with wavelengths of 630nm-700nm.

Infrared light is invisible and is effective for use on the surface of the skin as well as penetration of about 1.5 inches into the body. Infrared sits right next to red light on the electromagnetic spectrum at 800nm to 1000 nm.

The wavelength infrared puts out is longer than the wavelength of red light, which allows infrared to penetrate more deeply into the body. The longer the wavelength, the deeper the penetration. Thus, the reason infrared provides some similar, but some completely different benefits than red light. The science behind these concepts has been around for centuries (see quick note at the bottom of blog).** Both have become available as effective wellness services.


The Benefits of Infrared Heat


Infrared is classified as light energy but we do not see it. We feel it as warmth. It is safe because all humans produce IR and it is easily absorbed by our tissues. How does infrared do it? When it enters the body, it breaks up fats and toxins that are trapped in water molecules, it makes us sweat to let them out and therefore an infrared session is one of the best ways you can naturally detox your body!

The beneficial effects after absorption into the body include:

Pain relief

increased blood flow and reducing inflammation


Breaks up fat and toxin in cells for release form the body

Weight Loss

Boosting metabolism

Breaks up fats in cells to release from the body

Skin rejuvenation


Improved sleep

Improving diabetes and heart function

Increase blood flow


Helps with repair

Increased blood flow

Stimulation Fibroblast and Collagen formation

DNA repair

Cell and protein growth

Decreased pain


The Benefits of Red Light (LED)

Residing right next to near infrared on the spectrum, red light can (obviously) be seen! Many red-light therapy systems use small amounts of infrared along with red LED lights. Infrared penetrates deeply while red light works on the surface of the skin. Red Light LED produces its effects by stimulating collagen production because 700nm wavelength of Red light therapy is optimal for Collagen I production. While penetrating the skin, Red light LED:

Reduces wrinkles

Builds Collagen

Repair sun damage

Cellular repair

Better blood flow

Better lymphatic drainage

Decreased inflammation

Fading scars and stretch marks

Decrease hair loss

Stimulating positivity

How They Work Together

As youve noticed there are similarities between infrared and red light LED. They are both natural, drug / chemical free, non-invasive, effortless, safe, and users have reported no adverse short or long term side effects. Actually, users report AMAZING effects! While both therapies are beneficial,  the type you should choose depends on the outcome you desire. If you want to treat skin conditions on the surface,  Red light LED session is focused and effective. If there is toxicity in the body or stronger metabolic effects are desired, an Infrared session may be the better choice.  An Infrared session is a more holistic solution to wellness because it can provide skin rejuvenating benefits (like those of Red Light LED), but it can also help you burn calories, release toxins, increase blood flow, ease pain and put you in a state of utter relaxation.

To wrap it up, red light and infrared therapy each provide diverse benefits. Many people will utilize both.We currently have Red Light LED Light Stim Panelst, red & near infrared pads, infrared lamps and other far infrared heating pads.
