Is Depp really looking that bloated?
He's still way above average for his age, but his jaw has become less defined, his hair has thinned and receded, he's probably had hair transplant work done too and/or uses cosmetics, and of course he has lines and wrinkles, though far less than the average 52 year old. He's doing well for his age and has always been well above the curve in looks and hair, but even he isn't immune to aging.
