26 and Drooping Face PLEASE Help Me!!

I am a 26 year old mom of 3.. Up until my last pregnancy all was good with my skin except for slight bags i've had all of my life. Well, in the last 9 months i have lost all of my baby weight but.... now my face looks terrible, My upper and lower eyelids are sagging and my lower ones you can see veins through. I have like fat pockets on my lower cheeks by my mouth which have created new lines when i smile.. :( Also i have been doing facial exercises and using the Dermawand.. Do you believe these work? Or am I causing myself more damage?
