아니요, red light therapy does ~ 아니다 use ultraviolet (UV) 빛. Red light therapy uses visible red light (typically around 630–660 nanometers) and sometimes 근적외선 (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) 빛 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 ~ 아니다 include UV rays, red light therapy:
- Does ~ 아니다 tan the skin
- Does ~ 아니다 damage DNA
- Is considered non-ionizing and safe for repeated use
사실은, red light therapy is used to repair sun damage and support healthy skin, the opposite of what UV light can do.
결론
빨간불 치료 is not ultraviolet light. 대신에, it uses safe red and near-infrared wavelengths to promote healing, 염증을 감소, and support skin and tissue health — without the risks associated with UV exposure.
