25 year old with sagging laugh lines! What is the best long lasting filler? (Photo)

I have very oily, acne prone skin so most of my teen & early adult years I avoided moisturizer in fear of it clogging my pores and causing more breakouts. I've since learned the error in my ways, but it seems the damage is done and my confidence is gone. I also lost 35 pounds last year making the sagging more noticeable. I fear for how my skin will look when I really start to age since it already looks like this. Do I need a filler or would a mini face lift be more beneficial? Thanks in advance!
