Can Red Light Therapy cause skin cancer?

No, there exists no such reports or findings about Red Light Therapy. It is the sun’s UV rays that cause an increased skin cancer risk. Those wavelengths don’t exist in Red Light Therapy, but they do exist in some other light treatments, such as tanning beds. That’s why The Radiation Protection Agency [FDA regulates the use of tanning beds and tanning lamps in the US] has specific rules about how tanning beds can be used. The red lamps used in Red Light Therapy are household lamps and are not usually classified as medical equipment, either.
