How to use

How to Use


  1. Position the Panel

    Place approximately 6–12 inches from the area you wish to treat. For full-body sessions, position the panel vertically or mount it securely for hands-free use.

  2. Set Duration & Timer

    Turn on the panel and select your desired session time — typically 10–20 minutes per area, 3–5 times per week. Shorter, consistent sessions are more effective than longer, infrequent use.

  3. Select Light Mode


    Red (660 nm): Surface skin renewal, collagen boost, fine-line reduction


    Near-Infrared (850 nm): Deep tissue recovery, circulation support, inflammation relief

    You can use both wavelengths together for maximum results.



  4. Relax & Recharge

    Sit or stand comfortably while the LEDs deliver therapeutic light energy. Keep your eyes closed or use protective goggles if facing the panel directly.

  5. Post-Session Care

    No downtime is needed — continue your normal routine. Regular use supports cumulative benefits for skin health, energy, and recovery.
