As I became older, I worked very hard fighting wrinkles and fine lines. Volume loss never occurred to me, but when my once full cheeks started to resemble the mouth folds of a bulldog, I knew it was time to do something. I Googled "smile lines," and my search eventually led me to Bellafill (previously known as Artefill). I chose this filler, as it is supposed to last at least 5 years or more....
