What happens if an acne spot treatment isn't used in one spot?

The title pretty much asks it all. Things like duac or clean and clear spot treatments, what happens if you were to put it over a broader region and not just one spot? Could it cause some kind of bad reaction?What happens if an acne spot treatment isn't used in one spot?
you know, i have always wondered the same thing... i use mine to cover my whole face or at least to cover the entire area that i tend to break out instead of just on my visible acne.


i find that it works the same if used on occasion. once i started doing it everyday i seemed to get more breakouts than usual... but that's just me.
