Hello everyone. I am a former acne sufferer and have been interested in blue light therapy for about a decade.

Over the years, I have researched the literature regarding blue light and acne. I have purchased many products to compare to the output studied in literature. The bad news is that many blue light products suffer from incorrect wavelength and/or insufficent power. There are a few that do a good job (for example Tanda and other small units). However, they are relatively small and to treat the entire face is usually impractical. I am unaware of a commerical full face product that has the correct wavelength and power for a practical treatment. What I mean by practical is that low output power can be compensated by time. The full face units that I am aware require a prohibitiviely long treatment time to get optimal benefit.

So here is my question. What is the interest level in a product that:

(a) has the correct wavelength as determined via light spectrometer (about 415nm)

(b) delievers sufficient power as determined via comparison to literature

proven to destroy a given % of acne bacteria as a function of time. This is done in a research environment in petri dishes.

(d) treats the full face or a large percetange of the face in 5 minutes or less

Thanks everyone. My colleague and myself (both PhD educated and have access to the proper equipment) are interested in providing an improved solution for blue light therapy. If there is sufficient interest, we can do this. Even if a product is not produced, we plan on reporting output data from common units to better inform the community.

Also, if you are using a blue light product that you would like evaluated, let me know. We do not want to compete with something that already exists. Perhaps there is something that we are missing. Thank you for your time.
