I just heard a report about plastic surgery and what it's realistic to expect from facial procedures, what processes of aging can affect the outcome etc. The presenter and the surgeon they interviewed kept saying things like
"As we can see, Renee Zelwegger used to have a very full and convex eyelid area. Now there's a lot less volume and that's one of the effects expected from an eyelid operation.
Of course we have no idea whether she's had a eyelid operation, this is total speculation and of course we accept everything she says about her natural lifestyle and lower stress levels. But probably if someone did have an eyelid operation it would look exactly like that."
