The main principle involves near-infrared light penetrating the skull, where its photons are absorbed by neurons in the prefrontal cortex, leading to increased production of cytochrome c oxidase (CCO). As a catalyst, CCO enhances mitochondrial oxygen utilization efficiency, generating more adenosine triphosphate (ATP). ATP is the direct energy source for brain function; its increase can help improve brain power, especially in cases of mental fatigue or aging. Additionally, 40Hz pulsed light enhances gamma oscillations in neural connections, speeding up cerebrospinal fluid flow, which helps the brain quickly enter a focused and active state for complex tasks.

Yes, our product is very safe. The power density of the light emitted by our product is 250mW/cm², well below the US and international safety standard of 1000mW/cm². Moreover, our product has undergone rigorous safety and EMC testing by certified authorities and has passed relevant certifications in the US, EU, Japan, China, and more. However, if you feel any discomfort while using it, please stop and contact our customer service.

There are no strict restrictions on usage time. Generally, use it when you experience the following signs of brain fatigue:

1. Prolonged mental activity (e.g., exams, creative work, overtime) resulting in low energy, slow reactions, and mental fatigue.
2. Poor sleep quality over time, feeling tired and sluggish in the morning.
3. Difficulty concentrating, reduced learning and memory capacity.
4. Elderly family members showing signs of forgetfulness and slow reactions.
5. Memory issues caused by COVID-19-related "brain fog."

Use once a day for best results, ideally for at least seven consecutive days.

Each session lasts 15 minutes. The system automatically runs for 15 minutes, so no need to time it yourself.

It takes about 2 hours to fully charge the product from zero. A full charge provides 150 minutes of use, or 10 sessions. There are indicator lights for low battery and full charge. Please refer to the user manual for details.

The product is suitable for both elderly and children. However, it is not recommended for children under 12, who are unlikely to experience brain fatigue, or for seniors over 80, who may experience natural cognitive decline. It is also not recommended for elderly individuals with a history of brain diseases such as stroke or cerebrovascular injury.

Our product complies strictly with international safety standards for laser and electronic devices. No side effects or adverse reactions were reported during pre-market user testing. Furthermore, research papers by scientists worldwide on similar principles have not reported any side effects or adverse reactions.

Our product does not collect any user data and does not require an internet connection for use.
