my reuteri probiotic topical is working after only 1 week. i take a reuteri pill and open it and mix with water then put it on my face before bed. I have noticed a dramatic reduction in oiliness of skin, new acne, and redness! the topical also zaps zits by the morning and is working beautifully. i beleive it is due to this study:
"J Microbiol. 2012 Feb;50(1):137-42. Epub 2012 Feb 27.

While it is generally accepted that Propionibacterium acnes is involved in the development of acne, other bacteria including Staphylococcus epidermidis have also been isolated from the acne lesion. The interaction between Lactobacillus reuteri, a probiotic bacterium, and acnegenic bacteria is unclear. This study examined the effects of L. reuteri on the proliferation of P. acnes and S. epidermidis. Human-derived L. reuteri strains (KCTC 3594 and KCTC 3678) and rat-derived L. reuteri KCTC 3679 were used. All strains exhibited significant inhibitory effects on the growth of P. acnes and S. epidermidis. The proliferation of P. acnes was decreased by 2-log scales after incubation with L. reuteri for 24 h. In addition, the proliferation of S. epidermidis was decreased by 3-log scales after incubation with L. reuteri for 24 h, whereas the growth of L. reuteri was unaffected by P. acnes or S. epidermidis. Among the L. reuteri strains examined, L. reuteri KCTC 3679 had the strongest inhibitory effect on the growth of P. acnes and S. epidermidis, followed by L. reuteri KCTC 3594 and L. reuteri KCTC 3678. Interestingly, reuterin, an antimicrobial factor, was produced only by L. reuteri KCTC 3594. The most pronounced the antibacterial activities of L. reuteri were attributed to the production of organic acids. Overall, these results suggest that L. reuteri may be a useful probiotic agent to control the growth of bacteria involved in acne inflammation and prevent acne."
