INSIGHT

Consistency Determines Results

  • Consistency determines accumulated benefits and discontinuing loses effects.
  • Red light results are often subtle and appear over months, like diet or meditation.
ADVICE

Pick Devices By Your Specific Goal

  • First define your goal: local tissue, facial anti-aging, hair, or systemic longevity.
  • Choose device type and settings based on that specific goal.
ADVICE

Use Low Intensity For Facial Skin

  • For facial anti-aging use lower irradiance (≈10–50 mW/cm²) rather than high-power panels.
  • Avoid powerful panels on the face because higher intensity can harm results.
