I have two vertical creases on my forehead that begin at my nose. Are these what are called frown lines? I am not much of a frowner so I don’t know why I have them. What injectable filler would you use to decrease these creases? Are there some fillers that are longer lasting than others?

Yes. The vertical lines are usually due to repetitive frowning action. Two muscles are primarily responsible for the lines and therefore, it would be better to use Botox rather than filler. I advise my patients to try the botox first and after a week or two, if lines persist then fill it with one of the fillers (Juvederm or Restylane).
