Something interesting I wanted to share. My doctor (not my dermatologist) suggested I take probiotics after antibiotic use. Over this past summer I took Accuflora and broke out on my face pretty badly. I didn't attribute the breakout to the probiotic at first, but I stopped taking it after about a month, and the acne subsided. I assumed I had broken out because the product contained traces of dairy. So this past month, I tried another probiotic (this time vegan) that had very high ratings on Amazon. However, not long after I began taking it, I got another breakout. I stuck with it for almost a month, but became annoyed and stopped. A few days after stopping, I'm breakout free.
Now, I think probiotics are beneficial and I'm disappointed that I can't easily take them. I don't want to dissuade anyone from using them, but I wanted to share my experience with them.
