"Phototherapy with blue (415 nm) and red (660 nm) light in the
treatment of acne vulgaris", British Journal of Dermatology 2000; 142: 973-978, P.PAPAGEORGIOU, A.KATSAMBAS AND A.CHU
The parameters in the above effective study were
415nm
4.23 mW/cm^2
15mins / day
I'm pretty sure deep blue light diode bulb can achieve such parameters. |

the omnilux will be around 400-500 dollars and the minimarvel is
225.
i dont why the big difference in price is if the blue
omnluix
415nm
40 mW/cm2
mini-marvel
415nm
143.5 w/cm2
is mW/cm2 differnent than w/cm2? |

143.5 W/cm^2 doesn't make any sense, it's HUGE power density that's going to burn your skin if correct
probably it's 143.5 mW/cm^2
The prices of LED devices for skin therapy are overblown out of proportions and are based on marketing strategies not on how effective the device is or how much it costs to build it. Simply buy a deep blue LED light bulb and you will have the same device for 10 times lower cost. |

hi orange thank
do you know what the conversion is mW/cm2 to W/cm2
like the one that is 143.5 w/cm2 is that really 14.35 mW/cm2?

The prefix 'milli' means 'one thousandth' so the conversions are
mW = 0.001 W and W = 1000 mW
143.5 W/cm^2 = 143 500 mW/cm^2 (it can't be that high, it's a typo) |
