The benefit to going out, enjoying your life and being around other people IS that you are doing those things. You're hopefully then being happier, you're not worrying about your skin as much, you're doing the things you want to do regardless of acne. And maybe having a positive outlook and trying to enjoy life means you're not stressing so much and that's helping your skin - because we know stress and acne are linked (at least for some people).
Don't know what you're friend is going on about with the bacteria etc unless they're referring to how immunity is normally built up (immune response to recognised antigens etc) but that wouldn't have anything to do with acne - that's more for illnesses
