Red versus blue – why compromise?

The RejuvULite can provide either Red 660nm, Blue 452nm or both colors simultaneously.

LLLT (low-level laser therapy) or photobiomodulation products and studies cite spectrums of light such as: 450nm, 635nm, 810nm, etc. What this stands for is the wavelength of light measured in nano-meters (nm), and indicates the exact color of light. As seen in the figure, we perceive Red light when the wavelength is in the range of 650 to 800nm. We perceive Blue light to be in the range of 460 to 480nm. Studies have shown that different wavelengths have different benefits and uses. While not complete, a short summary is shown below.

Benefits of each ‘color’ (wavelength)

Red – associated with healing

Uses in LLLT often cite higher wave-lengths such as Red as most effective with healing. There are many examples of Red light therapy, including this study:

Wound-healing effects of 635-nm low-level laser therapy on primary human vocal fold epithelial cells: an in vitro study.

Infrared – associated with pain relief

Infrared and red are often associated with pain relief, such as this study:

The Use of Low Level Laser Therapy (LLLT) For Musculoskeletal Pain

Blue – associated with acne

Blue light is often associated with benefiting acne, such as this study. Cited within:

“One mechanism of action of phototherapy for acne is through the absorption of light (specifically blue light) by porphyrins that have been produced by P. acnes as a part of its normal metabolism, and that act as endogenous photosensitizers. ^49,53 This process causes a photochemical reaction and forms reactive free radicals and Singlet oxygen species which in turn lead to bacterial destruction (Figure 5).^49,53 ”

Figure 5 is a link to an illustration indicating the benefits of blue and red light when treating acne.

Why compromise?

When designing the RejuvULite for our friends and family that is now available to you, we didn’t want to compromise on the RejuvULite, such that we designed in the ability to use either Red, Blue, or both simultaneously. By doing this, we can provide a product that was aligned with studies that were shown to benefit the healing process of dermatological surgical operations, lacerations, sports injuries, and acne, and many more, and all with one product.

Further benefits

In the future, we expect to see many more benefits and we don’t want to be tied to just Red or Blue. There are now even treatment options using lasers for issues such as issues such as Toenail fungus. This is supported by a few commercial products available along with several scientific studies. This particular study uses both red and blue light treatments, with 12 minute durations of LLLT for up to 4 weeks. As compared to taking a harsh drug such as Sporanox that even requires monitoring liver health prior to taking it, photobiomodulation would be a huge benefit. Areas such as this ensure the benefits of LLLT and photobiomodulation will become more mainstream as time goes on.
