A newly filed patent contains a proposed rosacea treatment using small bands of infrared radiation between 790nm and 900nm with a power between 1 and 100 mW/cm^2. The unit proposed could be a LED device, used from twice a day to every 10 days. An energy density between 3 and 180 Joules/cm^2 is proposed.
Infrared Light is in the invisible spectrum below red, with wavelengths from 700nm to 2,000nm. We know that infrared light penetrates skin tissue more effectively than visible light.
An example device described is the OMNILUX Plus, which is promoted as “(Infra-red) works as a combination therapy with the Revive (red) head for even better skin rejuvenation, ideal for deeper lines and wrinkles”. OMNILUX Plus is based on a matrix of Infra Red LEDs, which provide narrowband 830nm light. This device is not currently promoted as a treatment for rosacea, so it seems that this patent covers using an existing treatment method for a new condition – rosacea.
The example treatment regime used an OMNILUX Plus unit at 830nm (+/- 0.5nm), using 55 mW/cm^2 at a distance of 1-10cm from the skin for 20 minutes with a power of 66 Joules/cm^2, twice a week for four weeks. Goggles were used and the unit was further placed 3-5cm from the patient’s nose.
The patent says that the patient enjoyed substantially reduced telangiectasia and reduced inflammatory papules.
United States Patent Application 20090270847, Lee; Seung Yoon, October 29, 2009
A method of treating erythematotelangiectatic rosacea or papulopustular rosacea in a subject comprises exposing the subject’s skin in need thereof to narrow-band infrared radiation at a wavelength(s) in a range of between 790 nm and 900 nm and having a band width of between 0 nm and 20 nm, in an effective dose to treat erythematotelangiectatic rosacea or papulopustular rosacea and essentially not to cause photothermolysis of the skin. Alternatively, a method of treating erythematotelangiectatic rosacea or papulopustular rosacea in a subject comprises exposing the subject’s skin in need thereof to narrow-band infrared radiation at a wavelength(s) in a range of between 790 nm and 900 nm and having a band width of between 0.1 nm and 20 nm, in an effective dose to treat erythematotelangiectatic rosacea or papulopustular rosacea. A kit for such methods comprises a radiation source generating narrow-band infrared radiation at a wavelength(s) in a range of between 790 nm and 900 nm, the narrow-band infrared radiation having a band width of between 0 nm and 20 nm and having a power density of between 1 mW/cm^2 and 100 mW/cm^2, and a manual instructing a user how to use the narrow-band infrared radiation for treating erythematotelangiectatic rosacea or papulopustular rosacea.

I bought a hand held LED light with both blue and red lights (not an Omnilux). It appears to be working very well. Many would be papules have started to come up but after 1 or 2 treatments (3 minutes) have disappeared. The blue lights are 420nm and red are 670nm.
The red light seems to work just as well as the blue on these blemishes.
Is it possible that the LED light could kill demodex mites? I always seem to get outbreaks in the same places. Touch wood all is clear after 3 weeks using the device.
The secondary benefit is pores appear to be smaller. It’s a bit inconvenient moving the light around the face and having a cord but the benefits are worth it.
