There are several way to approach this, depending on how blunt, polite or technical you’d like to be. You could say, “She has fake ___,” or “her ____ are fake”. However, this would be rather blunt or rude. One common euphemism is “She’s had some work done.” (1) Have you seen Monica? She looks so young. I think she’s had some work done. (2). Jennifer you look amazing. Tell me the truth — have had some work done? Another way to say it is the same as you expressed in your question: “plastic surgery”. Laura has had plastic surgery on her lips. Recently, people have started saying “cosmetic surgery” to avoid the word “plastic”. Betty doesn’t like her nose and says she’s saving up for cosmetic surgery. Similarly, you will hear terms like “cosmetically enhanced”. Example: In class, we discussed how models with cosmetically enhanced figures set unrealistic and unhealthy beauty standards for the girls who look up to them.
