Launched just in time to keep you out of the harmful rays of the summer sun, custom sunlight technology company Solius Labs Just for It’s a portable light panel that falls into a whole new category: over-the-counter light therapy technology, previously limited to medical settings. The FDA even created a new product code for the device in order to allow it to be used without a prescription, according to a press release.
In the United States, Solius Pro has been approved by the Food and Drug Administration (FDA) specifically to stimulate vitamin D production in people ages 22 and older.
“Solius UVB light therapy provides 12 times the health benefits of the sun’s ultraviolet (UVB) rays with 99% less overall UV risk,” Solius Labs CEO Chris Cable told CNET. “UVB light has been clinically proven to cause some… The most important vital processes in the body“.
This is not another SAD lamp
Solius is not like other light therapy products on the market, as it uses different wavelengths in the light spectrum. “Sad lamps and Red light devices “Use visible light and do not activate UV-responsive biological pathways that are essential for health and longevity,” Keppel explained.
Solius Pro can be hung on a wall or door frame to deliver your dose.
Solius Pro Skin Evaluation
All it takes is one light therapy session a week, lasting less than five minutes, rain or shine. However, the amount of UV rays harmful to the skin is reduced. A full year of such sessions provides roughly the same total UVB radiation as five minutes of natural midday sunlight, but with less risk, the release said.
The $2,995 portable device is designed for home use, measures 20 x 24 x 2.5 inches, weighs 7.1 pounds, and has 132 UV LEDs. It can be hung on a wall or door and plugged into a standard power outlet. Using the built-in sensor in Solius Pro, the Solius app guides the user through a skin assessment that captures skin pigmentation measurements and analyzes them using the Solius algorithm to deliver a dose of UVB treatment.
This personalization algorithm was created using approximately 10,000 skin samples from around the world, featuring a range of skin tones and pigmentation. To maintain safe and consistent dosing over time, the Solius system also includes skin response, treatment history, positioning data and user feedback for future sessions.
132 LED lights provide UVB curing.
Where you will receive your dose
“Safely dosing UVB from natural sunlight is almost impossible,” Keeble said. “Even on sunny days, factors such as time of day, season, latitude, cloud cover, air quality, skin tone, and individual skin sensitivity to UVB make it difficult to consistently achieve a clinically useful UVB dose without harming the skin.”
Additionally, there is difficulty in providing the right amount of UVB to stimulate the body’s beneficial biological pathways while remaining below an individual’s threshold where sunburn and skin damage can occur. Solius’ patent-pending skin analysis system makes dosing the benefits of UV light from the sun possible, but according to the company, it does so using 50% less total UV radiation than prescription narrow-band UVB (NB-UVB) devices.
Once your assessment is complete, the app will guide your session, which is usually less than five minutes and is designed for use on your back, from waist to neck. The app will ensure you’re wearing goggles, monitor your location, track your session and progress, and even block you from accessing the device between sessions.
“The user’s back provides a flat treatment surface that enables Solius to deliver a highly uniform dose of UVB that ensures meaningful biological effects over the entire body while keeping the face and eyes out of the treatment field,” Keeble said.
The dose of UVB radiation will be directed to your back, from your neck to your waist.
How to tell if Solius Pro is working
The goal is to provide users with biologically beneficial wavelengths of sunlight in a controlled environment, but with less than 1% of the total UV risk from sunlight.
Solius Pro uses a targeted UV wavelength of 293nm and focuses 95% of the light output within the UVB action spectrum, which is associated with stimulating vitamin D production. It avoids ultraviolet (UVA) wavelengths that can cause skin damage and increase the risk of skin cancer.
When asked how users will know if Solius Pro is working, Kiple stated that “health outcomes can be tracked through objective measures such as vitamin D levels, DEXA scans (an imaging test that measures bone health and body composition), stool samples, blood pressure, and patient-reported assessments.”
For vitamin D production, which Solius Pro is licensed to stimulate by the FDA, users can measure the effect with a baseline blood test before starting treatment and then 25-OH vitamin D tests after eight to 12 weeks of use, with retesting every two to three months.
during August 2025 Randomized controlled trial Funded by Solius, which included 69 people divided into treatment and control groups over 21 weeks, participants experienced an average increase of about 10 ng/ml in serum vitamin D levels without skin damage or visible tanning.
“Many users report improved mood and energy soon after treatment, along with better sleep, concentration and overall well-being over time,” Keeble added. “Beyond vitamin D production, researchers continue to study how UV exposure affects bone health, cardiovascular function, immune signaling, metabolism, and the gut microbiome.” These topics are the focus of Solius’ ongoing research.
You can track your Solius Pro sessions on the connected app.
Solius Pro is not recommended for everyone
While Solius Pro is safe for most adults when used as directed, Kiple acknowledged that it is not suitable for everyone, including people with photosensitivity disorders or a history of skin cancer.
In the above Trial August 2025The Solius regimen was well tolerated, with no serious adverse events, but 52% of participants experienced minor adverse events, such as redness and itching.
Before use, it is important to review the device user manual and talk to your doctor about any concerns.
“Continuous weekly Solius sessions help maintain the sunlight-dependent processes that our bodies depend on,” Keeble said. “Over time, continued treatment with Solius may help address some of the physiological effects associated with insufficient sun exposure that often lead to an increased risk of premature aging and disease.”
Cost and when to ship
Solius Pro is now available in the US, and costs $2,995 plus membership. Founding members receive a free lifetime membership with access for up to eight people. Otherwise, membership is $100 per year or $10 per month.
Solius Pro is HSA/FSA eligible, but with this type of purchase, membership is sold separately in the Solius app.
The Solius Pro Lighting Pad includes goggles ($52), a skin measuring cone ($25), a suspension system ($100), and a 10-foot detachable power cord ($23). You also get 30 days to return your device and a 1-year warranty.
The Solius Pro will start shipping in July.
