A New Light Therapy Device For Oil / Acne Improvement

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!

Oily Skin Clinical Trial - Here's Your Chance If You Live In Usa!

I've been keeping an eye on this product for some time now. It's a topical oil reducer. If you live in USA you have a chance to get into the clinical trial which have recently started:


Of course I live in Melbourne, Australia so it's off limits for me!

Oily Skin - Try Reducing The Ambient Temperature

08 September 2012 - 09:03 AM

This is something that has taken me a long time for me to realise: the ambient temperature affects my skin's oil production.

I've noticed that when I'm in a warm / hot environment for a long period (1 hour or longer), my skin produces more oil than normal. Conversely when I'm in a cold environment my skin produces less oil than normal.

This is obvious in 2 respects: the first is that I can actually see the change in oil on the skin surface after a period of time; the second is that my skin is in much better condition acne wise when I am in a cold environment for a prolonged period of time.

So of course I've recently been turning my house's heater down / off...
