Photobiomodulation is a research-based treatment method that suggests certain wavelengths of red and near-infrared light can produce a range of physiological effects on cells. Among its corpus, in this case, two technologies highly regarded for this treatment involve laser and red light devices. As their popularity and accessibility continue to rise in the wellness industry, one question arises: Is one more effective than the other in imparting physiological benefits?
Explore the difference between these two types of photobiomodulation treatments, and discover which one suits you best with the team at ROJO Light Therapy in this article.
Both red light therapy (RLT) and laser treatments operate non-invasively through the use of specific light wavelengths to stimulate cellular activity, reduce inflammation, and enhance recovery. They have both been proven effective for treating conditions such as arthritis, muscular injuries, skin conditions, neuropathy, and wound healing. They’re most popularly used in areas such as physical therapy, sports medicine, skin enhancement, and pain management.
The most significant differences between these two treatments are their light wavelengths and light distribution.
Red light therapy devices emit red light wavelengths within the ranges of 620 nm to 750 nm, while near-infrared wavelengths function from 780 nm to 2500 nm. Meanwhile, most laser treatments use wavelengths between 600 nm - 1000 nm.
The effects of these wavelengths, however, have to do more with the way these two devices emit light. Lasers have a pin-point focus, providing a full concentration of light on a targeted area, which can also work more effectively on the cells. On the other hand, red light devices emit light at an angle, causing their impact to refract, which also weakens as it moves further away from its source.
While this might seem like laser treatments have the advantage, that’s only true if you’re treating an isolated area of the body at a time. Examples include treating cosmetic issues, small wounds, or pains that affect only a small area. For anything larger, red light therapy devices are ideal since they cover a much larger surface area at a time.
Lasers are a very expensive technology and, thus, are much less accessible to end users. And while some spas and clinics may offer their use, the cost of each session may be overwhelming for some. On the other hand, red light therapy devices are already widely available at various price points, from professional units to affordable at-home devices, making them more accessible to the masses.
There are already various laser therapy devices in the market, mostly for cosmetic uses, however, using them at home poses certain risks. Improper use of these devices can cause various injuries from mild skin burns to irreversible damage to the eyes. Red light therapy devices, on the other hand, especially those designed for home use, are considered totally harmless.
Ultimately, the decision between which would be better suited for you depends on your needs, budget, and lifestyle. For a targeted approach for specific issues such as scar healing, laser treatments would be better. However, for broader health and wellness concerns, red light therapy offers a convenient and affordable option.
