Will Juvederm fillers fix my mental crease? If so, how will the fillers affect my chin shape when I smile? (Photo)

Thank you for the question and for including photos. If performed properly, Juvederm should treat the crease without changing the shape of your chin. Make an appointment with a physician who uses multiple products so that there are options when choosing a filler. Good luck.

For a mental
crease such as yours, a combination approach with BOTOX® Cosmetic followed by
Juvéderm® or Restylane® may produce the best results. This helps soften the
line between your lower lip and chin by relaxing the underlying muscles and
adding more tissue volume. Remember that all injectables are temporary
solutions, and you may need to repeat treatments once or twice a year to
maintain optimal results.

Fillers work great in this area, a little botox/dysport to the chin would do well too.  I suggest seeing a cosmetic dermatologist who specializes in lasers and fillers.  Best, Dr. Emer.
