Photobiomodulation is a science-based, safe approach for supporting brain health and function
This technology has been researched in thousands of studies in animals and humans, demonstrating beneficial effects on the brain, such as supporting healthy cerebral blood flow, brain function, and mood, among other effects.
Photobiomodulation benefits
The science of photobiomodulation
Hundreds of studies have been done in healthy people to improve cognition and mood, and in people with Alzheimer’s, depression, traumatic brain injury, and Parkinson’s disease, showing beneficial effects.
Professor. G. Herkes, Australian National University, School of Medicine and Psychology
“Photobiomodulation (PBM) is a form of light therapy that has been shown to have multiple clinical benefits due to its enhancement of the mitochondrial electron transport chain and the subsequent increase in mitochondrial membrane potential and ATP [energy] production. PBM also modulates cellular signalling and has been shown to reduce inflammation. Clinically, PBM has been used for decades to improve wound healing, treat pain, reduce swelling and heal deep tissues. Pre-clinical experiments have indicated that PBM has the potential to improve the clinical signs of Parkinson’s disease and to provide neuroprotection.”
Dr. A. Liebert, School of Medical Sciences, University of Sydney, Australia
“Photobiomodulation was shown to be a safe and potentially effective treatment for a range of clinical signs and symptoms of Parkinson’s disease. Improvements were maintained for as long as treatment continued, for up to one year in a neurodegenerative disease where decline is typically expected.”

Deliberately low price
YuthLabs brings photobiomodulation to the people
Most devices cost $1,000 to $3,000 - not because they are better, but because they can.
YuthLabs Cap is a lower-cost, high-quality cap, bringing photobiomodulation into the reach of everyone.

Frequently Asked Questions
Essential information you need to know
Why are most photobiomodulation helmets so expensive, and why is the YuthLabs cap much cheaper?
Photobiomodulation helmets are often very expensive because:
- Some devices have been tested in clinical trials, which cost a lot of money and this drives up the price.
- Each helmet uses slightly different wavelengths, so the helmet can be patented as a “novel device”. This way, no one else can sell this helmet emitting these specific wavelengths, allowing the company to charge higher prices.
However, research has shown that many different wavelengths improve Parkinson’s disease, Alzheimer’s disease, and brain health!
In fact, the wavelengths that work best are the ones that have been most researched and cannot be patented anymore (they constitute “prior knowledge”). This enables YuthLabs to produce a photobiomodulation device:
- That is much cheaper; we don’t have to run expensive clinical studies or trials again - these have been already done before by others.
- A device that has the best and most researched, ideal wavelengths, pulse rate, and energy density. We don’t have to pick some new wavelengths or other parameters in order to be able to patent our device so we then can quote a (very) high price.
The YuthLabs Cap has an extra third wavelength of 1064 nm. Why is this important?
Most photobiomodulation devices only use one or two short wavelengths (e.g. 660 nm or 810 nm). Long wavelengths (1064 nm) have various extra benefits:
1. Deeper penetration into the brain, reaching the basal ganglia, which includes the substantia nigra, where dopamine is produced:
“The comparison of three representative photobiomodulation wavelengths, 660 nm, 810 nm, and 1064 nm, for transporting photons to the human head using a Monte Carlo simulation showed that 1064 nm is the optimal wavelength due to its reduced light scattering. Although other photoreceptors (such as water) also absorb photons with higher wavelengths within this range, 1064 nm has less light scattering due to its longer wavelength, thus having deeper penetration ability for the human head.”
- Dr. Y. Yang, based on studies by Professor F. Gonzalez-Lima, University of Texas at Austin, USA
2. Longer wavelengths could directly support energy production in mitochondria, and be a more ideal wavelength for cytoprotection (protection of cells), nitrogen oxide release, and support healthy blood flow and inflammation levels.
"Our findings illustrate the efficacy of photobiomodulation for cytoprotection, nitric oxide (NO) release, inflammation changes, improved blood flow, and the regulation of heat shock proteins such as Hsp70."
“Photobiomodulation improves mitochondrial function, lower inflammatory cytokines, aids neuronal differentiation and plasticity, helps dopamine release for better neuronal function, and most importantly, lower blood sugar levels while offering protection to the neurons and glia.”
- Professor P. Chazot, Durham University, UK
Does the light penetrate the skull?
Yes, research in people, primates, and human cadaver skulls, show that various wavelengths can penetrate the skull. Longer wavelengths can penetrate the skull even better (that is why the YuthLabs cap also produces a long wavelength of 1064 nm).
Furthermore, many studies show that many health effects of PBM therapy do not even require the light to penetrate the skull.
For example, light of specific wavelengths opens (dilates) blood vessels around the skull, which leads to improved blood flow to the brain.
PBM also activates stem cells that reside in the bone marrow of the skull, which then can travel to the brain to support healthy repair.
PBM also activates endothelial cells (the cells which line the blood vessels) around the skull, which secrete substances that can travel to the brain, exerting health effects there.
What is the ideal power density (mW/cm2) and energy density (dose)?
Many devices offer too much or too little energy.
Ideally, the power density (“irradiance”) is 100 mW/cm2, being in the goldilocks zone of not too much and not too little to be clinically effective.
The total dose of energy (“energy density” or “fluence”, in J/cm2) delivered to the brain is another important parameter, taking into account the amount of time the device is used.
To be in the effective and safe zone, scientists recommend using a dose of around 60 J/cm2 when using photobiomodulation on the head. 60J/cm2 of energy reaches the skull, it’s estimated that around 1 to 3 J/cm2 penetrates the skull and reaches the brain tissue.
Our YuthLabs Cap delivers 100 mW/cm2 and a dose of 60 J/cm2 during a treatment of 10 minutes.
This is in line with the scientific recommendations, and provides an ideal middle ground, derived from data coming from more than 50 devices and hundreds of scientific studies, in which power densities are used varying from a few mW/cm2 to hundreds of mW/cm2.
Be mindful that many photobiomodulation devices, including by popular or seemingly esteemed brands, actually quote irradiances for their devices that are far different than when tested by an independent lab!
What is photobiomodulation?
Photobiomodulation uses low-level red or near-infrared light to stimulate brain cells. It supports healthy mitochondrial function, ATP production, and inflammation.
This non-invasive therapy can improve cognitive function, mood, and neuroprotection.
Are there scientific studies about Photobiomodulation Therapy?
