Can anyone explain the difference between wrinkle fillers and primers?  The LAST THING I need is another product to add to my vanity top but every once in awhile when I am not in flattering lighting I notice...yikes...I have both fine and deep wrinkles.
I assume fillers are like spackling holes in the wall before painting?
Also, I know that powder is verboten as it "settles" in wrinkles.  However when my skin gets oily in the summer (I have combination skin)  I use one of those blotting powders.  Should I be using blotting sheets instead so as not to deposit anything on my skin?  Ah...so many questions.
 
Please enlighten me, fellow forum members and thanks for your input.
