or too much brushing and using flouride toothpaste? who knows, so many variables!

I do not think so, acne around mouth usually occurs in hormonal acne or as fluoride toothpaste reaction.

Could be due to a lot... you might put your hand around your mouth sometimes, it could be due to fluoride, perhaps it's just hormones, or maybe you just shove food in your face so fast it inflames the skin (lol... I'm guilty of that).

I'd suggest changing toothpaste first. That is what I did... used to get all kinds of spots around my mouth, which imo were the worst kind of acne because you use your mouth every day! After switching toothpaste and doing a lot of other things differently with diet & medicines, I can't remember the last time I had a spot within a few centimeters of my mouth.
