Doctor A’s Answer:
Treating the glabella creases (vertical frown lines between eyebrows) may require both a filler (Restylane/Juvederm) and a paralytic (botox/dysport). The paralytic agent stops you from making the expression that caused the lines in the first place. If you don’t have any lines when not making that mean face, then all you will need is Botox or Dysport. Either of these products work great and if you use them regularly you might never get creases at all. This is why I suggest people start with Botox/Dysport in their 20’s. But if you are a little late to the party, then your creases may need to be treated with a filler like Restylane. The Restylane will fill the crease for a partial instant improvement but more importantly it will stimulate collagen growth in the area which (along with relaxing the muscle) may completely correct even deep creases over a few months. The collagen will persist well after the Restylane itself has dissolved. In fact, it may last indefinitely if you continue to use a Botox or Dysport. Even extremely deep glabellar creases may be completely fixable using that combination. In summary, prevent the crease with Botox/Dysport, repair the crease with a filler like Restylane or Juvederm.
Your neck banding may improve with a paralytic. This is an affect that works better on some people than others. It generally requires a higher dose of Botox or Dysport. Certainly it is possible to cause swallowing issues, but that would be very unlikely if the injector knows the proper location for injection. The swallow muscles are quite a bit deeper than the muscles that cause the banding. I truly doubt you will have any correction of jowls using Botox/Dysport in the neck.
