Ingen, red light therapy does ikke use ultraviolet (UV) lys. Rødt lys terapi bruker synlig rødt lys (typically around 630–660 nanometers) and sometimes nær-infrarødt lys (around 800–850 nanometers), which are both on the opposite side of the light spectrum from ultraviolet.
What’s the Difference Between Red Light and UV Light?
- Ultrafiolett (UV) lys has much shorter wavelengths (100–400 nanometers) and is known for causing sunburn, skin aging, and increasing skin cancer risk with excessive exposure.
- Rødt og nær-infrarødt lys 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 ikke include UV rays, rødt lys terapi:
- gjør det ikke brun huden
- gjør det ikke skade DNA
- Is considered non-ionizing and safe for repeated use
Faktisk, red light therapy is used to reparere sun damage and support healthy skin, the opposite of what UV light can do.
Konklusjon
Rødt lys terapi is not ultraviolet light. I stedet, it uses safe red and near-infrared wavelengths to promote healing, redusere betennelse, and support skin and tissue health — without the risks associated with UV exposure.
