blue light therapy and bacterial proliferation

I've been using the Tanda light with both the blue head (414nm) and the red head (630nm) for acne & anti-aging. The blue light hasn't been working great for me, so of course I got a bit lost in internet research land today, and came across this sentence:

"At low fluencies, both 415 and 455 nm enhanced proliferation of S. aureus..."

http://www.ncbi.nlm.nih.gov/pubmed/20662022

I am slightly worried by the idea that low-level blue light therapy at around 415nm could cause the proliferation of s.aureus (Staphylococcus aureus). S.aureus is nasty for lots of reasons, but can cause its own kind of pimples along side p.acnes bacteria.

Curious if anyone has any thoughts about LLLT blue LEDs and s.aureus proliferation!

Thanks!

Don't know about s.aureus proliferation, but I do have some experience with LED blue light.

I sometimes have acne, usually seasonally or after hair removal. I found blue light to be quite effective and helpful, even on quite big ones... For the big ones, it usually takes 3-4 day for them to completely disappear and for the smaller ones 1-2 days. I have also found that I can use it as prevention, so for example, after hair removal, I use it for 2 days and I don't have any skin issues Smile

I have Sirius Aurora, and blue light gives me obvious effects, and for that I am quite happy with that gadget. I use it once per day on the area of interest for 3 minutes on full (I am not a very patient person).

I tried using red and green light, sometimes regularly for up to a month, but didn't notice any benefits so gave up. Perhaps there are some benefits with longer use, I don't know...
