Solius Labs Launches the First FDA-Cleared Personalized Light Therapy Device for Recovery

The Hidden Costs Of Sun Exposure

Solius Labs has launched Solius, the first FDA-cleared, over-the-counter personalized UVB light therapy device for home use. It's built to deliver the health benefits of sunlight — safely, efficiently, and on your schedule.

The device scans your unique skin tone and calculates your optimal dose of UVB light. Then it delivers it in a 5-minute session, once a week. No sunburn. No guesswork. No sitting outside hoping you got it right.

It comes at a moment when new research is challenging decades of sun-avoidance advice.

We've Been Fighting the Wrong Battle

For 30 years, doctors told us one thing: stay out of the sun. Wear sunscreen. Seek shade. Cover up.

And for good reason. Skin cancer is real. Sunburn does damage.

But somewhere along the way, the advice went too far. So we started avoiding the sun altogether. And that decision came with a cost nobody was measuring.

‍

What the Research Actually Says

A UK Biobank study tracked outcomes across a massive population. The finding: people who avoided the sun didn't just lower their skin cancer risk. They raised their risk of dying from other causes. By a lot.

Researchers in the Journal of Internal Medicine went even further. They said sun avoidance is a risk factor for death of a similar magnitude as smoking.

Read that again. Same ballpark as cigarettes.

And a 2024 study in the Journal of the National Cancer Institute looked at over 62,000 people. It found that lifetime UVB exposure wasn't linked to higher melanoma risk once researchers adjusted for UVA exposure. In the highest UVB exposure group, melanoma rates actually went down.

Turns out not all UV light is the same. UVA is the one tied to higher risk. UVB behaves differently.

Why Your Body Actually Needs UVB

UVB light does more than make vitamin D. It's tied to:

• Bone health. It helps your body absorb calcium, which protects against osteoporosis.
• Brain and mood. It boosts serotonin and dopamine.
• Heart health. It releases nitric oxide, which supports healthy blood pressure and circulation.
• Gut health. It supports gut lining integrity and a balanced microbiome.

So the sun isn't the enemy. The lack of it might be.

The Problem With Getting UVB the Old-Fashioned Way

Here's the catch. Getting UVB from actual sunlight is messy.

Too little, and you miss the benefits. Too much, and you're back to burn risk and skin damage. The dose depends on your skin tone, the season, your location, the time of day. Almost nobody is getting it right.

A Smarter Way to Get UVB

This is the problem Solius was built to solve.

A quick rundown on how it works:

• 1x a week. One 5-minute session delivers a full week of UVB benefit.
• 12x the benefit. Solius delivers 12 times the UVB health benefit of the sun, safely.
• 99% less risk. A full year of weekly Solius sessions carries less UV risk than five minutes in the afternoon sun.

It's not more sun. It's the right wavelength, in the right dose, without the tradeoff.

We spent decades being told to fear the sun. The data tells a different story. Sunlight isn't just about vitamin D — it drives real, measurable processes across your whole body.
