Red, Blue & Infrared Light: Which Colors Should You Choose?

One of the most amazing and exciting things about Red Light Therapy is that it can non-invasively treat every external part of the human body. And internally, Red Light Therapy’s ability to increase circulation can benefit the entire musculoskeletal system, the organs, and even veins, arteries, and blood cells. Red Light Therapy can even stimulate the body’s own regeneration of nerves and tissues. And best of all, especially for those seeking a more natural approach to pain relief, Red Light Therapy is fast-acting, non-addictive, risk free and totally safe, as well as highly effective, and dependable! Plus, Red Light Therapy can actually accelerate the body’s own innate healing ability!

Let's Explore the Differences Between Red, Infrared & Blue Light

Blue LED Light in the beneficial range of 460-470 nm is safe and risk-free, and has no reported adverse side effects. The concerns regarding potential problems from Blue Light exposure from computer screens, tablets, laptops, televisions, and smartphones is associated with Blue Light wavelengths in the potentially problematic lower range of 415-455 nm. (HealthLight’s blue diodes are at 465nm)

Blue LED Light can be defined as light given off from light-emitting diodes (“LEDs”) in the visible light spectrum between the wavelengths of 400 to 500 nanometers (nm).Blue Light sits on the spectrum between violet and green. While Blue Light is readily absorbed by the skin and is very beneficial, it does not penetrate as deeply into tissue as does Red Light and Infrared Light. Blue light (400–470 nm) is shallow in it's penetration making it a perfect choice for skin conditions in the epidermis, the upper layer of the skin.

Wavelengths of Blue LED Light between that same range of 400-470 nm have been found to be antimicrobial. Blue LED Light can inactivate the cells of of bacteria and fungi. Even bacteria resistant to antibiotics such as staph and MRSA has been shown in studies to yield to blue light. Blue light offers value to treat cuts, scrapes, bites, burns, stings, and surgical incisions. Blue LED Light can help keep open wounds, sores, and skin eruptions free of germs. This anti-microbial nature of Blue LED Light has relevance for both health and beauty applications.

HealthLight, a leading U.S. manufacturer of professional medical-grade FDA-cleared Red Light Therapy devices, offers Therapy Pads containing Blue and Infrared LEDs:

  • HealthLight’s 104 Face Mask offers 52 blue diodes (465 nm) and 52 red diodes (630 nm). (No infrared diodes.) The pad fits over the eye area like a standard mask, but can also be used over or under the chin and lower face; around the forehead area; the front or back of the neck; and either side of the face for maximum skin benefits.

  • HealthLight’s 132 Medium Blue Therapy Pad offers 60 blue (465 nm) diodes and 72 infrared (850 nm) diodes. This pad measures 8” x 9”, making it convenient for treating almost every area of the body.

Red, Infrared, and Blue Light Work Together

Blue LED diodes are often paired with red diodes and/or infrared diodes in LED Therapy Pads. This is because different colors or wavelengths of LEDs have different levels of penetration within the body. This difference in depth of penetration results in different effects at the molecular, cellular, and tissue levels.

Red Light penetrates more deeply into the body than blue light. But the deepest level of tissue penetration is achieved by Infrared Light. So combining LEDs of two or three colors/wavelengths may be one of the best options for creating a therapy pad for varied applications. And mixing different colored LEDs together on a single pad allows the different wavelengths to complement each other and work together synergistically to bring greater benefits to the body. One scientific study suggested that, “…synergistic effects of mixed light is due to synergy between the antibacterial and anti-inflammatory effect of blue and red light respectively.” Avci P, Gupta A, Sadasivam M, Vecchio D, Pam Z, Pam N, Hamblin MR. Low-level laser (light) therapy (LLLT) in skin: stimulating, healing, restoring. Semin Cutan Med Surg. 2013 Mar;32(1):41-52. PMID: 24049929; PMCID: PMC4126803, p.6.

HealthLight also makes a tri-color Therapy Pad containing Red, Infrared, and Blue LEDs to give you the optimum benefits of all three wavelengths. Their 180 Long Tri-Color Pad measures 5” x 16" and is perfect for long or narrow locations such as down the back or legs, across the chest, or wrapped around an arm, leg, or foot. This pad contains 180 LEDs: 40 blue (465 nm) diodes, 40 red (630 nm) diodes, and 100 infrared (850 nm) diodes.
