Most buyers run ~20–30 min per area; if you want to repeat the same area, wait a bit before the next session. Many devices have a 30-min auto-off for safety

Your Questions About Our Organizer Answered
Clarity and confidence for your purchase decision.
How long should I use it per area? Can I do 30 mins on multiple spots?
What’s the difference between 660nm and 850nm? Do I need both?
660nm red supports surface/skin (collagen, circulation) while 850nm NIR reaches deeper muscle/joint tissue—that’s why dual-wavelength belts are popular.
Will it fit my waist / can I use it on different areas?
Belt include elastic/Velcro straps. They’re designed to wrap back/waist/knee/shoulder with adjustable fit.
Will it work if I’ve already got months of soreness?
Absolutely — many users report relief even after chronic discomfort by using consistent sessions of the 660 nm + 850 nm light combo.
