The 14 day of antibiotics my SD appeared on nose sides and hairline after about half year of 99% easy control. Definetley provoked by the antibiotics which is probbly related to the death of "good" bacteria in the body. So now I'm 100% sure this is fungal desease coused by a fungi that all humans has on the skin (the reason why someone with SD cant infect other people) and the problem is due to the bacteria that controls those fungi is dead and Melassezia takes spread. I hope a long course of probiotics might be back some control of it.
Bottom line is and my advise to all is to take antibiotics for a lifesaving treatments only.
P.S. And when you need to take ABs don't forget to take vitamins of group B, because they are mainly produced by bacteria in the gut and you'll have deficiency if you don't supply them during AB intake.
