Question 1

How does this product work, and who is it suitable for?

Accepted Answer

The product works by applying specific wavelengths of light to the body, and is suitable for adults with everyday relief needs. It features 210 dual-wavelength LEDs at 660nm and 850nm; once absorbed by cell mitochondria, the light supports the body's natural cellular energy production. Many users report it relieves post-workout muscle soreness and lower-back tightness from prolonged sitting, helping improve localized conditions.

Question 2

What is the recommended usage frequency and session length?

Accepted Answer

We recommend starting with 3-5 sessions per week, 10-20 minutes per body area each time. Afterwards you can adjust flexibly based on your own comfort, taking care not to exceed the maximum session time stated in the manual. Regular, moderate use feels better than occasional long sessions with long gaps in between. Stop immediately if you feel any discomfort.

Question 3

Do I need eye protection when using this product?

Accepted Answer

Avoid looking directly at the light source during use; wear light-blocking goggles when necessary. When the product is running, the 660nm wavelength emits a soft red light visible to the naked eye, while the 850nm near-infrared light is invisible. Although the light intensity is within a safe range, deliberately staring at the LED beads may cause eye strain, so avoid direct exposure.

Question 4

Will it cause discomfort for sensitive skin, and what does normal use feel like?

Accepted Answer

Most people with healthy skin feel no obvious discomfort; those with sensitive skin can start with short sessions to check tolerance. The contact surface is skin-friendly soft fabric. In normal use you'll feel only a gentle warmth — no stinging or burning. If redness, itching or similar occurs during use, remove the wrap and stop immediately.

Question 5

How should I clean and maintain this product?

Accepted Answer

Always disconnect the power before cleaning, and simply wipe the surface with a well-wrung soft cloth. Never immerse the whole unit in water or wash it. Since it contains a built-in LED array and circuit components, do not use corrosive cleaners. Store it in a dry, well-ventilated place, avoiding heavy pressure and sharp objects on the contact surface to protect the LED beads.

Question 6

What are the warranty and after-sales policies?

Accepted Answer

The product comes with official after-sales support; for specific warranty terms, contact the store's online customer service. If you receive a defective product (non-user-caused), contact customer service within the specified period for handling. For operation questions or troubleshooting during use, official customer service can also help. Do not disassemble the unit yourself.

Question 7

How is this product different from red light panels, therapy mats and narrow waist belts?

Accepted Answer

This wrap-style therapy belt differs clearly in use cases from the other three types. Standing panels suit non-contact irradiation of large areas; flat mats suit covering the whole back while lying down; narrow waist belts only cover a small waist and abdomen area. Weighing 660g, this wrap flexibly fits the back, knees, shoulders and more, balancing coverage with portability.

Question 8

What should I keep in mind for long-term use?

Accepted Answer

For long-term use, keep it regular and moderate — don't blindly increase session length or frequency. Follow the manual strictly, and never use it on broken skin or open wounds. If discomfort persists during use, stop and consult a professional. Storing it away from moisture and pressure will extend its lifespan.

Question 9

Does it come with instructions?

Accepted Answer

Yes — the package includes clear instructions; the operation logic is simply setting a duration. If anything is unclear, contact customer service — after-sales support is part of the product.
