Undecided Question

So i used this Aveeno daily scrub for like a week, and now my face is flaky…?

i thought i needed to add an exfoliator to my daily face care, (though i didnt use it daily), so i bought this aveeno stuff. i noticed it made my face really tight, so i discontinued my use of it. this was maybe a month ago? and now my skin around my cheeks is flaky, and dry, and my moisturizer isnt working. (i use proactiv) i know i might have made a mistake, but how can i fix it?
