Flash lamps for hair removal were cleared by FDA to market in
the U.S. in 1997, although flash lamps had been used since the
early 1970's in photoepilators. Below are clinical studies discussing
modern flash lamp hair removal, as well as selected articles about
flash lamps on related topics. Flash lamp technology is also called
IPL (intense pulsed light), ILS (intense light source), full spectrum,
non-coherent, and broadband light.
Gold (1997): 
37 subjects getting one treatment had

treatments respectively over one year had "satisfactory"
results 6 months after last treatment. With photos.
Schroeter (1997): 40 women had facial hair treated, with 77% reduction

reduction was 33% 6 months after treatment. (Full version of
