A New Light Therapy Device For Oil / Acne Improvement
Posted 05 January 2013 - 10:47 PM
It's jsmithson, back with yet another interesting topic! I came across a new science study about a Korean light therapy device in the British Journal of Dermatology:
"The clinical and histological effect of home-use, combination blue-red LED phototherapy for mild to moderate acne vulgaris in Korean patients: a double blind, randomized controlled trial"
You gotta pay to read it so I'll summarise it for you here. They tested a device from Ceragem Medisys called the MP 200. It's a combination blue (420nm) and red (660nm) light device that you use at home. You irradiate yourself for 5 minutes twice a day. After 12 weeks they found some very interesting results:
- Acne lesion counts down by average 77% and 54% (inflammatory and non-inflammatory respectively) in the treatment group. No change in the control group.
- Average 25% reduction in the area of the sebaceous gland (I assume this is a cross sectional area) in the treatment group. No change in the control group.
- Molecular markers for inflammation and sebum production (SREBP-1, IGF-1R, TLR-2, IL-1a, IL-8) were down in the treatment group. No change in the control group.
- Virtually no side effects (10% of treatment group reported 24 hours of mild dryness at one point in the study!)
- The study compares the treatment in effectiveness to topical retinoids and antibiotics but with less side effects.
- The blue light kills p.acnes via a PDT reaction. Since p.acnes stimulates oil production and inflammation, a reduction in oil production and inflammation is seen after treament.
- The red light has an anti inflammatory effect and accelerates wound healing.
This study is good for acne but also for us oily folk. I haven't found anywhere that sells the device so I don't know how much it costs. If it's not really expensive (it's just a bunch of LED's after all) I'll give it a shot!

I purchased the Tanda acne and regenerating light therapy device back in 2008 before it was FDA approved in the US (it is now though),
Interesting that you are a new user since a few days ago, and that you seem to overwhelmingly refer in glowing terms to a single product.
I am way behind the times on this one. Doing a search on Amazon shows that there are many devices on the market that are based on this technology: Verilux Clearwave, Clear Rayz, Tria blue light system, BrightTherapy trident, acne 415 blue light therapy, Tanda Zap, etc. There are so many! They all seem to be based on the same science.
Doing a pubmed search shows that there's scientific evidence going back a decade that this technology is effective. Lots of papers - many use a specific brand and model of device.
Some issues I have with some of the devices above:
1. LED's are super cheap because they're mass produced in huge quantities. So why are all these devices so incredibly expensive?
2. Some of these devices try to force the user to upgrade the LED's while they're still useful. LED's last a very long time. The cynic in me is reminded of the shaving business model - where you make much more money if you can keep selling consumables.
I'm trying to get hold of a standard screw in globe containing high powered LED's direct from a lighting manufacturer. It's much cheaper than the stuff listed above and has a much stronger output.

I understand where you're coming from, i thought of how easy it would be to make this device at home for about 20$. But i have searched for the 414nm leds (for the light to work and penetrate the skin it needs to be between 400-420nm to kill the p acnes, from what i understand) but they are either not in stock or expensive and shipped from China or Japan. It would be very easy to make this device at home if you can get the leds. The tanda paper work says it is good for some 1000 uses i think, but i used it every day twice a day for the first 2 years and a lot of non regular use over the last 3 years, it is still working ok. They are expensive devices, but i didn't have health insurance at the time i bought it & for 500$ it was cheaper than a derm visit& rxs for a month. Also some people will pay anything to have a possible cure for their acne. They have gotten a lot cheaper since & I'm sure once they become more main steam (if they do) they will be avail in Walmart or something for cheap. & just to make sure i said this correctly, this didn't cure my acne, it helped a lot, but i still broke out. And as soon as i stopped using it my acne came back a few weeks later in full force. But it still helped my acne more than most other things i have tried.
