I don't think many dermatologists hang around here, maybe mtdoc is the most qualified in this forum for medical things.
I didn't look at the specifics or if it uses UV light, but UV light can kill bacteria, and I don't know if acne is bacteria in the skin, but if you can get that UV light with the necessary safety precautions then it could be true.
But I'm just guessing since I'm not a physician.
Well I'm just a lowly family doc - I don't make the big bucks like the dermatologists. But I do treat a lot of acne and skin diseases (I live in a semi rural area that only has 2 dermatologists within 50 miles - both with long waitlists and restricrtive insurance acceptance). Acne is more an inflammatory issue than infection and the antibiotics that are effective work in part by reducing inflammation.
UV light has been tried for decades to treat acne. I remember getting UV light treatments as a teenager at the dermatology office!
I don't think it is very effective (and has risks) and the drugs they have now to treat acne work really well most of the time. I'm sure if this device really works it will be widely adopted.
And before the traditional medical drug haters chime in let me say I agree that big Pharma has way too much influence which is why I almost never prescribe non generic (still under patent, expensive) drugs unless there is no alternative. I don't talk to drug reps and we don't allow them to set foot in our office! I also encourage non-drug treatments whenever possible. Acne happens to be one of those diseases that drugs do work on and better than any non-drug treatment I am aware of. I'd be happy if I could prescribe an inexpensive electronic device to effectively treat acne!
I don't classify Accutane as *safe*, though it is no doubt very effective!
I had horrible acne as a teen and into my early 20's. If you looked pizza face up in the dictionary my high school graduation photo would be there.
When I turned 20 I realized I wasn't growing out of it. My first dermatologist put me on an oral minocyclin and an antibiotic/peroxide cream regiment. It cleared the acne up, but after being on both for a year I suddenly began experiencing intense joint pain and swelling. Three separate doctors couldn't figure out what was going on until I stumbled on an article at LUPUS.org about Drug Induced Lupus. Guess what antibiotic was one of the 50 or so drugs on their list known to cause DIL? Yup! XD (One doctor did have me stop taking the antibiotic for two weeks to see if it was the cause, but it's a fat soluble drug so the symptoms didn't go away straight off. Once I finally figured it out, it took almost 5 weeks before things started getting better.)
Sadly it left me with permanent joint damage. I ended up going through a course of Accutane; despite all the danger associated with it, that shit is a miracle drug. Not one acne breakout since!
I've since wondered why antibiotics are prescribed so much for acne treatment. I know my particular case was one in a million, but antibiotics are already way over prescribed in general (I'm looking at you, GPs). We're just engineering deadlier viruses, right?
