Inga, red light therapy does inte use ultraviolet (UV) ljus. Rött ljusterapi använder synligt rött ljus (typiskt runt 630–660 nanometer) and sometimes nära-infrarött ljus (cirka 800–850 nanometer), som båda är på motsatt sida av ljusspektrumet från ultraviolett.
Vad är skillnaden mellan rött ljus och UV-ljus?
- Ultraviolett (UV) ljus has much shorter wavelengths (100–400 nanometers) and is known for causing sunburn, skin aging, and increasing skin cancer risk with excessive exposure.
- Rött och nära-infrarött ljus have longer wavelengths, which penetrate the skin more gently and stimulate cell energy production without causing DNA damage.
Why Is Red Light Therapy Safe?
Because it does inte include UV rays, rött ljusterapi:
- gör det inte garva huden
- gör det inte damage DNA
- Is considered non-ionizing and safe for repeated use
I själva verket, red light therapy is used to reparera sun damage and support healthy skin, the opposite of what UV light can do.
Slutsats
Rödljusterapi is not ultraviolet light. I stället, it uses safe red and near-infrared wavelengths to promote healing, minska inflammation, and support skin and tissue health — without the risks associated with UV exposure.
