In Hollywood, aging is something most stars will do just about anything to avoid. Some have spent anywhere from $75,000 to $250,000 - and in some cases much more - for the chance to look decades younger. Cosmetic procedures have always had a place in the industry, and as stars get older, it's no surprise they want to look like they did in their 20s, 30s or even 40s. While some celebrities are thrilled with their results, others have been open about wishing they'd done things differently.
