Yeeeahsuggests that Madonna has had "bad" plastic surgery. She has likely had more than her fair share of surgery. In the images they post, she could either be freshly post-op or showing the signs of multiple procedures over time.
Too much facial surgery can contribute to a skeletal appearance that is not exactly attractive. As we have said before, there is a point of diminishing returns when adding more surgery. Then again, if she is freshly post-op things will likely improve.
