It's a trap in the same way drugs can be. When a lot of your friends have had a bit of work done here and there and it looks great on them so you try, and the first few bits look good. But from there it's really easy to go right off the deep end if you're the wrong type of unwell. Just like how in a friend group where everyone smokes a bit of pot from time to time and some people enjoy a line or two at a party, one person who joins the group may find themselves absolutely hooked.

Actors and media personalities are at high risk for body image issues, and cosmetic surgery is a really dangerous thing for people with such issues. I've known people who got a few cosmetic surgeries and were happy, some are much safer than others for it, but it's so easy for some people to fall into the trap of thinking that every perceived flaw should and can be fixed. Once you're there it's just body dysmorphia, no different from a stereotypical anorexic person, including inability to have a realistic view of one's body.
