How it works
Mechanism before marketing.
Red and near-infrared photobiomodulation are studied for skin rejuvenation. In controlled trials using defined outputs and schedules, researchers have reported improved wrinkle measures and increases in collagen density or collagen and elastic fibers.
Blue light is studied most often for inflammatory acne at wavelengths around 415 nm, sometimes combined with 660 nm red light. A blue-looking LED is not automatically an acne treatment.
What controls the exposure
The variables that change the biology.
What the evidence supports
There is human evidence for specific red/near-infrared and blue-light protocols. The strongest conclusions require a device’s measured output and a treatment schedule that matches the research.
What we cannot assume
Research has boundaries.
The suppliers provided wavelengths for KONKA and LAYOR, but not complete irradiance and dose data. That lets us identify the light programs, not promise the outcomes of a different clinical device.
Practical use
Use the technology thoughtfully.
- Follow the supplied session timing and eye-safety directions.
- More time is not necessarily better; photobiomodulation is dose-dependent.
- Do not use a cosmetic light device as a replacement for professional acne or pigmentation care.
