A question we often get asked is, “Which Joovv Light should I get?” Another common one is, “What wavelength configuration is right for me?” They’re great questions, especially considering we now offer the Joovv Light in 3 different sizes with 3 different wavelength configurations – a total of 9 different choices!
There truly is no “one size fits all”, which is why we try to help our customers with individualized recommendations by first learning more about their specific health, beauty, or fitness goals. Having said that, if you’d like to familiarize yourself with the available options, the rest of this article will help answer common questions and enable you to make a more informed decision.
Why do you offer 3 different wavelength configurations?
We offer the Joovv Light in configurations of red light at 660 nm, all near-infrared (NIR) light at 850 nm, or a 50/50 combination of these two wavelengths. Both of these wavelengths (660 nm and 850 nm) have been proven in hundreds of published clinical studies to enhance cellular health. Technically, the correct term for the study of light therapy is photobiomodulation (PBM). On that note, Dr. Michael Hamblin, one of the world’s leading researchers in the field of PBM, is on our scientific advisory board and has witnessed the positive results of both wavelengths in his research.
How does red light (660 nm) work?
The red LEDs in our Joovv Lights deliver light at 660 nm, which has been proven to be beneficial across multiple clinical studies, some of which we’ve explored in other articles. The main difference between red and near infrared light is that light wavelengths at 660 nm are more quickly absorbed by the outer layers of your skin – the dermis and epidermis. While some of the light energy can pass through to deeper tissue, a greater percentage is absorbed and used by your skin to produce collagen, resulting in a host of benefits like the reduction of wrinkles, enhanced skin tone, and the fading of scars and stretch marks.
What about near infrared light (850 nm)?
With virtually the same cellular response in terms of mitochondrial function, 850 nm near infrared light is also backed by a robust amount of published clinical literature. The primary differentiating characteristic is the ability of these wavelengths to penetrate into deeper tissue. With a lower absorption in the outer skin layers, a greater percentage of the photons from near infrared light are able to reach deeper within your body. This is supported by a multitude of studies that we’ve covered in other articles. An additional difference is that 850 nm LEDs produce a 30% higher irradiance using the same wattage. The combination of these factors leads to some impressive results using near infrared light at 850 nm. Lastly, one important thing to remember is that since 700 nm is the upper limit to wavelengths visible to the human eye, 850 nm is virtually invisible.
So, which wavelength configuration should I get?
The answer really depends on your health goals. If you are strictly looking for skin health benefits such as collagen production, reduced fine lines, and better overall tone and texture, a 660 nm Joovv Light would work very well. If, on the other hand, you are only seeking deep tissue treatment - including muscles, joints, and organs - then the 850 nm wavelength configuration would be best. The third, and our most popular option by far, is the combination configuration of both red and near infrared light. This configuration provides a lot of versatility in terms of both superficial and deep penetration of light energy. It’s optimal for overall health and essentially provides the best of both worlds – helping you look good AND feel great!
Which Joovv Light size - Mini, Original, or Max?
The best size for you really depends on your desired treatment area, how much time you have for treatments, and of course, what fits within your budget. If you just want to treat your face or another small area of your body, the Joovv Mini will work just fine. It provides a significantly larger treatment area than most light therapy products on the market and the LEDs are just as powerful as those in our larger devices. The Mini can be used for any area of your body, but would require multiple sessions to treat your entire body. It also includes a custom door hook and pulley system to allow for easy height adjustment to treat any area of your body.
The Joovv Original is 2 ½ times the size of the Mini and is capable of treating a good portion of your body. Using myself as an example, I’m 5’10” and at a distance of 12” away, it will treat from the top of my head to about my mid-thigh. So, for full-body treatment on one side of your body, you would need to use it twice. In simpler terms, once above your waist and once below your waist. It also includes a custom door hook and pulley system for easy height adjustment while hanging from a door.
The Joovv Max gives you the opportunity to treat your entire body all at once. At over 3 times the size of the Original, the Max delivers an amazing amount of light energy to your body in a short amount of time. It is optimized for full-body recovery after workouts, increased energy, and improved overall health. Unlike the Mini and Original, the Max is able to be supported horizontally (mounting hardware not included), which has become a popular option for use over a massage table.
So, there you have it! With the 660 nm, 850 nm, or combo configuration, along with Mini, Original and Max sizes, we offer a nice variety of light therapy options to help you reach your health, beauty and fitness goals!
