Mary Tyler Moore had to have a special glowing light on her during Change of Habit (1969) because she was already wrinkled due to diabetes. Standing next to Elvis in his glorious prime didn't help either. She looked bony and wrinkled with a constant glowing light that made her look sallow. She honestly would have looked more natural without her glow-light. She was also severely out-prettied by one of her female co-stars, which didn't help.
And yes, plastic surgery, except for extremely subtle work, is very distracting.
Speaking of Elvis... Priscilla has had some infamous work done that got a lot of negative attention when she was on Dancing with the Stars. She looks like a wax doll who is trying to look exactly how she did in the '60s forever. Her hands show her real age, though. Elvis fans have been making Joker/Priscilla manips and comparisons for years.
