My family have skin problems and after using a proprietary LED unit to treat cold sores, not only did it clear them up quickly than medicinal creams, I have not had another since. I decided after this sucess that I might be able to help by making a full face mask with a number of LEDs

It uses what is called Red Light Therapy which is the application of a narrow spectral width in the red or near infra-red spectrum to promote cell regeneration and reduce inflammation. It is believed that the displacement of NOMT (Mitochondrial Nitric Oxide) in cells leads to an improved healing performance
Use for 1 minute at least 3 times a day but not more that once in one hour (this could reduce effectiveness of the treatment). Do not use in conjunction with any creams including anti-viral applications for Herpes Simplex outbreaks (cold sores)

WARNING do not look directly at the light emitted from the leds, they are NOT lasers but are very bright

Step 1: Attaching and Wiring Up

Using a proprietary LED constant current driver designed for domestic led lighting was the actually the cheapest and simplest way to provide power. I obtained 5 x 1watt LEDs at 660nm which is the defined efficacious wavelength. These were in total with the the PSU USD20. I glued the leds into a face mask bought out of the childrens craft section at the local supermarket and connected the leds in series, + to - and so on. I connected the supply to the 2 outer leds making sure to keep correct polarity

Step 2: Firing Up

I connected the leds to the psu (I took the precaution to add a 1K linear potentiometer in the circuit at first). These are rated at 300mA, 1 watt

Step 3: Finishing Touches

Add a pair of wrap round sunglasses to the mask to avoid the unit shining directly in the eyes. Also take the precaution of only switching on once in place. Hope it works for you

Future development
Increase array of leds at a lower rating
Find a better mask or stiffen this one with papier mache
Fit a timer circuit to automate the 60 sec treatment interval
