Are you buying "Light Therapy" or just a "Lamp"?
Many ask: "I can get a red mask for $20 on Taobao. Why pay $400 for yours?"
Good question.
If you just want "red light," wrap Christmas lights around your face.
But if you want "anti-aging," you need the invisible power of NIR (Near Infrared).
Depth Match: 630nm vs 850nm
-
Red Light - 630nm:
- Red Light: Reaches surface only. Good for brightness, but weak on wrinkles.
-
NIR - 850nm:
- NIR: Reaches the dermis where collagen lives. It penetrates deep.
NASA's Discovery: The Mitochondrial Engine
Why is 850nm so powerful? NASA research gives the answer.
Inside your cells, there are engines called Mitochondria.
When 850nm hits them, they absorb the energy (like photosynthesis) and mass-produce ATP (Cell Energy).
-
More ATP = Energized Cells = Faster Collagen Production.
- Without 850nm, your cells are like hungry workers—too tired to fix wrinkles.
Buying Tip: It's Invisible!
Here's the trick: 850nm light is invisible to the human eye.
Customers often complain: "Hey! Half the lights are broken!"
Actually, those "broken" lights are the expensive NIR chips working hard.
- Tip: Check the specs. If it only says "Red Light" and not "NIR" or "850nm," it's just a red lamp. Don't expect it to erase wrinkles.
