I got terrible infections in both my scars, the second time around though I put a little tea tree oil in the bath and soaked in there for a while, and VOILA! No more scar infection. (I went on to have a vba2c ... and that proved to be great for avoiding infections )

Definitely take the probiotics, also look into some good quality fish oil, vit c, and vit e. My surgery stuffed up my skin good and proper, the vbac fixed it, which leads me to believe that surgery messed with my hormones, so perhaps you need something for maintaining hormone levels?
