No, red light therapy does not use ultraviolet (UV) light. Red light therapy uses visible red light (typically around 630–660 nanometers) and sometimes near-infrared light (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?
- Ultraviolet (UV) light has much shorter wavelengths (100–400 nanometers) and is known for causing sunburn, skin aging, and increasing skin cancer risk with excessive exposure.
- Red and near-infrared light 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 not include UV rays, red light therapy:
- Does not tan the skin
- Does not damage DNA
- Is considered non-ionizing and safe for repeated use
In fact, red light therapy is used to repair sun damage and support healthy skin, the opposite of what UV light can do.
Závěr
Terapie červeným světlem is not ultraviolet light. Instead, it uses safe red and near-infrared wavelengths to promote healing, reduce inflammation, and support skin and tissue health — without the risks associated with UV exposure.
