These two pictures of Courteney Cox are only five years apart, with the image on the right being from 2015, which was right around the time when Cox began regularity using fillers.
However in 2017, Cox announced she was over it— "I’ve had all my fillers dissolved," she told New Beauty in June 2017.
"I’m as natural as I can be. I feel better because I look like myself... Things are going to change. Everything’s going to drop. I was trying to make it not drop, but that made me look fake. You need movement in your face, especially if you have thin skin like I do."
