The lips can swell up considerably after augmentation using injectables like Restylane. There seems to be a tendency for stars to go out in public with either their lips significantly swollen or just plain overdone. Brittany Murphy appears to be a prime example of this. The photo on the left is recent, the photo on the right is from 2006. Why do her lips look so overdone?
Because the top lip is huge. Many patients (and possibly surgeons) believe that the top lip should be larger than the lower lip. Unfortunately, this lip ratio only works naturally for ducks.
Lip augmentation can be very tastefully done, and can really enhance a person's appearance. It's very possible that she is just really swollen, and things will settle down nicely. Most injections are temporary anyway.
