my 3 month report on red diode light - ZERO result

[orangehrzn]

I did a 3-month split-face test with a red diode lamp (parameters below). I irradiated my right cheek/below the eye. The effect of the light on my enlarged pores, faint patchy redness from capillaries, faint lines below the eye was exactly ZERO - no difference, whatsoever from the untreated side. The effect of the light on inflammation and pimples was not tested because I don't have those frequently enough.

I did not observe any negative effect from the light in long term. Right after irradiation, the red vessels seem slightly more flushed but that goes away quickly. The lamp emits a little heat so I just keep it 1/4 inch away from the skin to prevent the heat from building up - skin just gets a little warmer if you don't.


Lamp:
My red light diode bulb is L-80S:
goldengadgets.com/product_info.php?cPath=12&products_id=329
It uses 4 Watts of electric power, the light is spread in a circle of diameter d = 11 cm - I put the lamp almost touching skin so that is the actual diameter over which the light is spread out.

POWER:
Assuming 1/4 of the electric power is converted to red light with the appropriate color the power is P = 1 Watt spread over area of a circle A = pi d^2 / 4 = 95 cm^2. The power density is

P/A = 10 mW/cm^2

Such power density is comparable to the studies of red/blue light for acne. On the other hand, the 'rejuvenation' studies of Omnilux use 8 times higher power 80mW/cm^2. From articles I talked about before, I am absolutely sure that even at such a high power, the effect of Omnilux on enlarged pores is close to zero since in one article I was able to see the pores unaffected on the before and after pics.


WAVELENGTH(COLOR):
I estimate my red light diode to be around 660nm since it's more red than orange (as 633nm would be). One of the tables in the Omnilux presentations has shown that red light 630-670nm can stimulate fibroblasts so I am in the required range. Moreover, there are devices on the market for photorejuvenation at 660nm.

DURATION:
During the first month and half I was doing 10 mins irradiation/day but after I've read the Omnilux presentations, I did 20mins/day for the last month and a half. Supposedly, the longer irradiation turns on the fibroblasts more.

PULSING:
I did continuous irradiation without pulsing.

I was wondering how your experiment was going.
Sounds like it was a dud.
There is quite the discussion on EDS Forum,Essential Dayspa about the various Lights and Gadgets.
It would be so awesome if you would share this info with the ladies and gentlemen.
And, thank you so much for sharing your results.
