ProActive
I used Proactiv for 2 years. Initially it made my skin very red for
a few days (due to sensitivity to benzoyl peroxide), but after that
it settled. However, my skin has since become really dry (though
pimple free now). I think only when you have very bad acne, you
should only spot treat your zits instead of putting acne treatment
all over your face. Overall Proactiv did work for me, but way too
drying.
