Why We Chose It
At Project Healthspan we spend hundreds of hours evaluating every leading light therapy device on the market. Our bar is high, and the Vielight Neuro Duo is currently the only cognitive light therapy device to meet it. Vielight's publication record, device quality, and clinical trial presence put them in a category of their own. This is one of the few devices where the science and the product are fully aligned.
Most people using the Vielight Neuro Duo notice improvements in focus, clarity, and mood within six to eight weeks of consistent use.[1b.26][1b.28] Some experience benefits sooner. Over time, many report that they can feel the shift a single session produces — the calm of Alpha mode or the sharp engagement of Gamma — which is part of what makes the device so practical for daily life. At Project Healthspan, we are proud to be partnered with Vielight — and more excited than ever to bring these tools to the people they can help.
The Bigger Picture
In clinical trials using the Mini-Mental State Examination (MMSE) — the gold standard cognitive assessment used in Alzheimer's research — tPBM produced average MMSE improvements of 2.6 to 4.8 points in patients with mild to moderately severe dementia.[1b.02][1b.25] By comparison, donepezil (Aricept), the most widely prescribed Alzheimer's drug, averaged +1.73 MMSE points in a large 12-week global study of over 1,000 patients — while commonly causing nausea, vomiting, diarrhea, and cardiac side effects significant enough that 5% of patients discontinue it. The newest FDA-approved drug, lecanemab (Leqembi), does not improve MMSE scores at all; it modestly slows the rate of decline — while carrying risks of brain swelling, brain hemorrhage, and deaths in clinical trials, with 21.5% of participants experiencing amyloid-related imaging abnormalities.
Safety Profile
Cognitive Light Therapy has been studied across a wide range of populations with a consistently clean safety record. Across published clinical trials — including those in elderly dementia patients — no serious adverse events have been reported. The light is non-ionizing, non-thermal, and does not damage DNA or tissue.
One study author described tPBM's results as achieved "without the serious adverse effects associated with current leading Alzheimer's drugs."[1b.02]
Benefits
- Improve cognition,[1b.26] memory,[1b.27] and functional creativity[1b.28]
- Enhance visual working memory[1b.11] and divergent creative thinking[1b.22]

- Try Light eligible: available to members for a 2-month evaluation period before purchase
The easiest way: in Elementor on the Celluma page, find any existing text widget, select it, go to Style → Typography, and set the font to Filson Pro Heavy. Even a single character in a hidden element would do it. Does that make sense, or would you like me to think of a cleaner approach? Occasionally wondering if claude is telling me the right way to do things but hey, here we go!
