A recent discussion encouraged me to experiment with other frqs for related pathogens and, according to Char, Malassezia species are one of the causes of acne. 

But there's no need to buy DNA frqs immediately. I've tried the CAFL set for Malassezia furfur for a few days and had great results. Note that I've been using electrodes, which for me worked better than a bean. You might not feel any hits from Malassezia furfur but keep repeating for a few days and see.
