Multiple references from the Daily Mail describe the issue of loose, stretchy or saggy skin that can appear after people lose large amounts of weight, particularly when weight loss is rapid. The articles say such skin can remain as folds or looseness even after weight has been reduced, and they frame the discussion around non-surgical remedies. According to the provided summaries, the expert featured in the piece discusses which approaches are considered effective and which are viewed as less likely to help, with the emphasis on cost and practical outcomes. The coverage does not cite specific medical procedures in the excerpted text, focusing instead on non-surgical measures and how readers can set expectations about results. Overall, the reports present saggy skin as a common post-weight-loss concern and position the expert guidance as a way to distinguish potentially helpful interventions from those described as ineffective or a waste of money.
