No, red light therapy does нет use ultraviolet (УФ) свет. Red light therapy uses visible red light (typically around 630–660 nanometers) and sometimes почти инфракрасный свет (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 (УФ) свет 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 нет include UV rays, терапия красным светом:
- Does нет tan the skin
- Does нет damage DNA
- Is considered non-ionizing and safe for repeated use
Фактически, red light therapy is used to repair sun damage and support healthy skin, the opposite of what UV light can do.
Заключение
Терапия красным светом is not ultraviolet light. Instead, it uses safe red and near-infrared wavelengths to promote healing, уменьшить воспаление, and support skin and tissue health — without the risks associated with UV exposure.
