Inspired by a European study, a team of Stony Brook University researchers looked into the potential impact of healthy human skin tissue (in vitro) being exposed to ultraviolet rays emitted from compact fluorescent light (CFL) bulbs…

“Our study revealed that the response of healthy skin cells to UV emitted from CFL bulbs is consistent with damage from ultraviolet radiation,” said Professor Rafailovich. “Skin cell damage was further enhanced when low dosages of TiO2 nanoparticles were introduced to the skin cells prior to exposure.” Rafailovich added that incandescent light of the same intensity had no effect on healthy skin cells, with or without the presence of TiO2.

“Despite their large energy savings, consumers should be careful when using compact fluorescent light bulbs,” said Professor Rafailovich. “Our research shows that it is best to avoid using them at close distances and that they are safest when placed behind an additional glass cover.”
