Jason Momoa - He was gorgeous in his teens/early 20s during Baywatch/Baywatch Hawaii but now has these freakish facial features from excessive weightlifting, steroid use and over-tweaked eyebrows. More cro-magnon man then hot.
Matthew McConaughey - has taken Botox and fillers too far that his face looks permanently frozen even plastic in the Lincoln automobile ads.
Sean Patrick Flannery - was a stunning twenty something in the Young Indiana Jones Chronicles, but has aged like a hard living roady. Looks like a completely different person, nothing like his younger self.
Jared Leto - The ageless Jared Leto. He must have the best plastic surgeon in the US, but despite his perpetually youthful appearance, it just feels wrong and somehow unattractive. People should age somewhat and not look exactly like their teen selves in mid-life. I find his line-less face off-putting along with his associations with the pedo-photographer & the rape allegations.
Danny Dyer - A cute teen but now middle-aged, bloated and overweight. Too many pints in the pub.
Henry Cavill - Godlike in the Tudors and the Immortals. Post comic book films he has kept the bulk to his detriment and all that muscle is quickly turning into blubber. He is sliding into fit/fat territory quickly.
The Harries twins - They achieved peak beauty/cuteness in their teens and now look gaunt and malnourished in their 20s.
